SECTION 1 - REGISTRATION AND PROGRAMMING YOUR 406 MHZ BEACONS

1.1 Programming

This SSAS beacon is programmed with a serialized Unique Identifier Number (UIN). In order for a security
alert to be routed properly, this beacon must be reprogrammed by an authorized ACR distributor before
installation or use can occur.

This beacon must be reprogrammed as follows:

• With protocol code for SSAS

• With the country code of the vessel’s flag state

• With the vessel’s unique MMSI

1.2 Registration importance

It is imperative that the owner of this 406 MHz beacon registers it with the National Authorities*. All 406
MHz beacons transmit a Unique Identifier Number (UIN) when activated. For SSAS the UIN programmed
in the beacon must be the vessel’s MMSI. Registration provides the security forces with up to date
emergency contact information, which will speed up the launch of a rescue operation. The national
authorities use the information to verify if an actual emergency exists. Valuable resources are wasted
every year responding to false alarms. For beacons that are not registered, the national authorities will not
know who you are, what type of vessel you have, your homeport, or who has a copy of your float plan. This
will delay the launch of the mission.

* National Authority is the governmental body that is responsible for SSAS registration database
administration for the country the SSAS is programmed for.

1.3 Where to register

The owner of a 406 MHz beacon (SSAS) should register it with the national authority of the vessels flagged
state, regardless of where they operate. Each beacon must be programmed with the country code of the
vessels flag state, and will only be accepted for registration in that country. To verify the country for which
a beacon is programmed, see the label with the UIN on the back of the unit. Beacons purchased outside
the flagged state of the vessel MUST

1.4 Registration in the United States

It is the owner’s responsibility to register 406 MHz beacons that are programmed for and purchased in the
United States. The national authority that accepts registrations in the United States is the National Oceanic
and Atmospheric Administration (NOAA). The owner should complete the enclosed registration form (Do
not confuse this with the ACR Electronics warranty card) and mail with the pre-addressed; postage paid
envelope to:

be reprogrammed by a properly equipped distributor for registration.

SARSAT beacon Registration,

E/SP3, RM 3320, FB-4

NOAA/NESDIS

5200 Auth Rd.

Suitland, MD 20746-4304

Online registration is now available. Please visit - www.beaconregistration.noaa.gov

The information provided on the registration form is used only for rescue purposes. The registration form
should be filled out and mailed immediately. Registration can be expedited by registering online or by
faxing the registration form to Fax # [phone]. Registrations should be faxed in the event the beacon
is to be placed in immediate service and followed up with the mailing of the hard copy form.

All registration forms will be entered in the 406 MHz beacon registration database within 48 hours of
receipt. A confirmation letter, a copy of the actual registration and a proof-of-registration decal will be
mailed to you within two weeks. When you receive these documents, please check the information
carefully and place in the SSAS annex of your vessel security plan. Do not affix the registration label to the
beacon. This may compromise the covert nature of the beacon. (See page 1). If you do not receive
confirmation back from NOAA, please call toll free 1-888-212-7283 for assistance.

Y1-03-0180 Rev. D 1

1.4.1 Commercial vessels in the United States

In the United States, commercial vessels that are required to have a radio station license are required to
modify that license when an SSAS is added to the vessel. Please update FCC FORM 605 to modify your
radio station license. For information on whether you need a radio station license, call toll free 1-888­CALLFCC (225-5322)

1.5 Registration outside of the United States

For use on vessels flagged in countries other than the United States, the sales agent should assist in filling
out the forms and sending to that country’s national authority at the time of purchase. To verify that the unit
is properly programmed for that country, view the UIN label on the back of the unit. In the event that the
beacon is not programmed for the country in which the vessel is flagged, the sales agent (if properly
equipped) MUST

1.6 Change of ownership or contact information

It is the owner’s responsibility to advise the National Authority of any change in the information on the
registration form. If the current owner of the beacon is transferring the beacon to a new owner, the current
owner is required to inform the national authority by letter, fax or telephone of the name and address of the
new owner. The new owner of the beacon is required to provide the national authority with all of the
information requested on the registration form. This obligation transfers to all subsequent owners. In the
United States registration forms are available from NOAA. Call 1 [phone] or visit

www.beaconregistration.noaa.gov

1.7 Commercial vessels worldwide

406 MHz SSAS beacons that are carried on commercial vessels world wide, should be registered with the
country where the vessel is flagged regardless of where the vessel operates. When a commercial vessel
acquires a 406 MHz SSAS beacon from outside of its flagged country; the beacon MUST
reprogrammed and register the beacon according to its flag state and its MMSI.

SECTION 2 - FALSE ALARMS

2.1 Prevention of false alarms.

There are a few precautions that should be taken to prevent false alarms:

Do not transport beacon within 1 meter (3.3ft) of a magnetic source.
Do not mount beacon within 1 meter (3.3ft) of a magnetic source.
Do not mount remote switches where they can be confused with another switch
Do not mount beacon where it can get wet.
Do not clean beacon with any liquid.

2.2 Reporting of false alarms

Should there be, for any reason, an inadvertent activation or false alarm, it must be reported to the national
authority of your vessels flagged state. The information that should be reported includes the SSAS Unique
Identifier Number (UIN), date, time, duration and cause of activation, as well as location of beacon at the
time of activation.

3.2 Beacon installation

3.2.1 The ThunderBird SSAS is shipped attached to its mounting bracket. Typically, the beacon must be

removed from the mounting bracket during installation. The beacon can be removed from the mounting
bracket as follows:

• First disconnect the 2-Pin waterproof connector on the left side of the beacon.

• Unbuckle the strap holding the beacon to the bracket.

The ThunderBird SSAS is intended to transmit covertly a security alert, notifying competent authorities
that the security of the vessel is under threat or has been compromised. A key component of the system is
its covert nature, which should be maintained as much as possible to protect the beacon from malicious
tampering. The ThunderBird SSAS is shipped in the “OFF” position. During the installation procedure,
leave the beacon in the “OFF” position to prevent false alarms.

Y1-03-0180 Rev. D 3

3.2.2 Mounting location

The location selected must be sufficiently rigid to support the weight of the total installation (approx. 2 lbs)
and at the same time consider vibration, exposure to surrounding hazards, such as equipment movement,
doors openings, personnel traffic, etc. The bracket should only be mounted to a flat surface at least
as big as the bracket. Mounting to a rail or post is not recommended.

Also to be considered in selecting a location for installation is the harmful effect that certain corrosive
vapors might have on the beacon. Under no circumstances should a location be selected for installation
where the beacon would be jeopardized by any foreign articles being temporarily or permanently
positioned during “at sea” or “in port” activities.

Do not mount or store the beacon within 1 meter (3.3 ft) of strong magnetic (such as loud speakers) or
electrical (such as radar or high power radio transmitter) fields. The beacon should not be mounted closer
than 1 meter (3.3 ft) to a navigation compass.

In order to maintain the required covert operation, the ThunderBird SSAS mounting location should be
hidden from the view of most personnel and all passengers and guests. Suitable locations include inside
an equipment closet or cabinet, under the navigation bridge and inside a closed equipment rack.

The bracket can be mounted in any orientation; however, the beacon controls and system connections are
designed for vertical installation. When selecting a mounting location the following should be carefully
considered:

• Routing of switch wires/cables. (Connects to top of mounting bracket.)

• Routing of RG-8U coaxial antenna cable. (Connects to top of beacon.)

• Routing of GPS interface cable. (Connects to top left part of beacon.)

• Accessibility to beacon control switch. (Top right part of beacon.)

• Visibility of test and Xmit LED’s. (Top left part of beacon.)

3.2.3 Hardware

Use three stainless steel pan head fasteners to secure beacon mount to surface. Size 3/16” or #10 bolts
can be used. (Not Supplied)

3.2.4 Installing the beacon in the bracket

The mounting bracket is keyed to prevent the beacon from being installed backwards. Install the
ThunderBird SSAS with the front label facing out. The strap should be tightened to secure the beacon
snugly in the bracket. Connect the 2-Pin waterproof connector on the left side of the beacon (see Figure

11).

3.2.5 Connecting the beacon to a GPS receiver via the optical interface (IR transmitter)
Your beacon comes with a NMEA GPS optical interface cable (transmitter plug with lead wires) that should

be connected to the ship’s GPS system. The IR transmitter plug attaches to your beacon, via the keyed
blue bezel on the top left of the beacon. The cable can be routed through the hole in the upper left corner
of bracket. The lead wires attach to the ship’s GPS system via the NMEA 0183 connector from your GPS
receiver. The black lead wire with white stripes should be connected to the positive transmitter pin (Data
Out). The black wire should be connected to the negative pin (Ground).

NOTE: The baud rate output for your GPS receiver NMEA 0183 should be 4800. Consult your GPS
manufacturer for correct installation.

3.3 Activation switch installation

• Per IMO’s SOLAS Chapter XI-2, Regulation 6: Ship Security Alert System:
Paragraph 3.1: “The ship security alert system shall be capable of being activated from the navigation

bridge and in at least one other location;”

Y1-03-0180 Rev. D 4

3.3.1 General information
SSAS beacons are required to have at least two remote activation points, one of which is on the navigation

bridge. Two switches are supplied with the ThunderBird SSAS. Contact the factory if additional switches
are required.

The switches are required to be protected from inadvertent activation and activate only with two
independent mechanical actions. These requirements are satisfied by the spring-loaded switch guard
attached to the switch when shipped. The switches must be installed with the guard in place.

3.3.2 Switch location
The switches are designed to be installed through a hole in a panel and require approximately 1” (25.4

mm) by 1” (25.4 mm) clearance on both the front and the back. The recommended panel thickness is

0.039” (1mm) to 0.106” (3.2mm).
There are some additional factors that should be considered when selecting the switch locations. A

primary consideration is installing the switches per IMO requirements: one on the navigation bridge and the
other in a secondary covert location. Each switch should also be installed in a location that will not draw
unnecessary attention, yet be easy to access. The switches should not be installed in a location where
they might be confused with other switches. Lastly, the wiring routing may also be considered.

3.3.3 Recommended wire
ACR recommends using stranded, tinned wire between 16 to 22 AWG to connect between the remote

activation switches and the beacon mounting bracket. Stranded wire is recommended to better withstand
the effects of vibration. Tinned wire is resistant to corrosion. The recommended wire gauge is a
compromise between weight and strength. ACR provides crimp-on terminal lugs for 16 to 22 AWG wire for
the connection to the mounting bracket. Other marine grade lugs (Not Supplied) can be used for different
gauge wire.

Because two wires are required to connect the switch to the mounting bracket, a two conductor cable is
ideal. This makes routing the wire easier and provides additional strength.

3.3.4 Switch installation
Cut a 0.638” x 0.638” (16.2 mm x 16.2 mm) square hole in the selected panel. The recommended panel

thickness is 0.039” to 0.106” (1.0 mm to 3.2 mm).
The switch should be pushed back into the hole from the front. It is recommended to make the wire

connections before installing the switch into the panel. Connect the wires to the back of the switch; one
wire to “COM” terminal and the other to “N.O.” terminal. There should be no connection to the “N.C.”
terminal. The wires should be soldered to the switch terminals (see Figure 1). Once the connections are
made, make sure the spring-loaded switch guard is securely attached to the switch and press the switch
assembly into the panel hole. The switch will snap into place.

Repeat the above procedure for the other switch.

3.3.5 Connection to mounting bracket
Route the switch wire from the switch locations to the ThunderBird SSAS beacon mounting bracket. Care

should be taken to route and secure the wire properly. The wires should then be trimmed to the
appropriate length.

If using the recommended 16 to 22 AWG wire, crimp the terminal lugs (provided) onto the wires. If other
wire is used, appropriate lugs (Not provided) can be used. Alternatively, the wire can be connected directly
to the terminal block on the mounting bracket (see Figure 2). Connect one wire from each switch to one of
the two terminals on the top of the mounting bracket by placing the lug under the screw and tightening the
screw. Repeat with the other wire from each switch in the other terminal.

3.3.6 Switch installation verification
To verify proper installation of the switches, the following procedure should be followed (requires two

persons, preferably with 2-way radio communications):

• Perform this procedure with all connections made between the switches and the beacon.

• The beacon must

a live transmission to the satellite system.

• With a multi-meter, measure the resistance between the two screws on the left side of the beacon.

This should be an open circuit (> 100 kΩ.) If not, check the switch wire connections to make sure the
two wires from each switch are connected to different screws on the mounting bracket terminal block.

• Depress each switch (one at a time) while measuring the resistance between the two pins on the

mounting bracket connector. The resistance should momentarily (as long as the switch is depressed)
read a short (< 10Ω.) If the resistance never reads a short, verify all connections are per 3.2.4 and

3.2.5 above.

be in OFF mode. Performing this test with the beacon in READY mode may result in

3.4 Cross dipole antenna installation

3.4.1 General information
The cross dipole antenna is intended for operation far away from a ground plane. With this in mind, the

location of installation should be carefully selected to keep the antenna as far from horizontal conductive
(metallic) planes as possible (see Figure 12).

The length of cable from the SSAS beacon to the cross dipole should be kept as short as possible. Secure
antenna cable (3 ft. maximum) away from antenna to reduce stress on antenna connector (see Figure 12).

A stainless steel 4 inch tall antenna mount is included with your SSAS kit. If the supplied bracket is not
ideal for the desired mounting location, the cross dipole has a standard female 1” x 14 thread allowing it to
be mounted to a variety of off-the-shelf brackets and masts.

Y1-03-0180 Rev. D 6

3.4.2 Mounting guidelines

• Minimum height above deck: 10 feet (3 m)

• Allowable obstructions: Obstructions are allowable only below the antenna.

There should be no conductive (metallic) objects in the entire
hemisphere above the antenna.

• Coaxial cable length: Maximum: 100 feet (30.5 m)

* Contact the factory if longer runs or different coaxial cable is
required.

• Coaxial cable type: RG-8/U marine grade

3.4.3 Antenna assembly
The antenna is shipped with the four elements removed from the housing. Before using the antenna,

these elements must be assembled to the antenna housing.
For each element, assemble as follows:

1. Slide the grooved end of the element into a hole in the side of the housing until it stops

2. Install and tighten appropriate set screw through hole in the bottom housing using included wrench

3. Pull lightly on the element to ensure it is tightly secured

3.4.4 Antenna installation
Select mounting location using guidelines and general information above. The top of a mast is an ideal

location for the cross dipole. Mounting to an existing spar or to a bracket attached to a mast is also
acceptable. See Figure 12 for examples. The antenna must be mounted with the connector pointing down
and the elements horizontal. If mounting on a spar or bracket, the antenna elements must be oriented
approximately 45° to the horizontal support when looking from the top or bottom, as shown in Figure 12.

Use one of the following methods to mount the antenna per the guidelines and general information above
with all four elements in the horizontal plane:

• The included mount can be used to attach to any small, flat, horizontal surface; i.e. the top of a mast or

a spar. In this case drill holes in the pattern of the mount and attach with marine grade screws as
needed (not supplied).

• The included mount can be used to attach the antenna to a round spar using U-bolts.

• The antenna can be mounted to any bracket or mast with the standard 1” x 14 thread.

ANTENNA INSTALLATION

FIGURE 6

3.4.6 Antenna installation verification
To verify proper installation of the cross dipole antenna, the following procedure should be followed

(requires two persons, preferably with 2-way radio communications):

• One person should be on the deck with an FPR-100 with line-of-sight view of the cross dipole antenna.

The FPR-100 antenna should be oriented horizontally and ideally be located directly under the cross
dipole antenna.

• With the FPR-100 ready to receive a test burst, the other person should initiate a Self-Test.

• If the FPR-100 successfully receives the test burst, then the cross dipole antenna is installed correctly.

• The FPR-100 can also verify that the ThunderBird SSAS is programmed correctly.

• If the test burst was not received, the FPR-100 may be too far from the antenna. Repeat the test with

the FPR-100 closer to the antenna. (Typically, an FPR-100 can receive a signal from the cross dipole
at a maximum range of 100 ft. (30.5m).

• If the FPR-100 still does not receive the test burst, check all coaxial connections from the beacon to

the antenna.

switches. At the remote activation locations, there is no indication that the beacon is activated. This is
intentional to ensure covert operation. The flashing red XMIT LED on the beacon indicates activation.

These are momentary switches installed on the ship that are used to activate

4.5.3 The ThunderBird SSAS should only be activated when the ships security has been threatened or
compromised. However, applicable personnel must be familiar with its operation so the beacon can be
activated when needed.

...........................................................................Stop if failed

3. Check RF Power/Battery................................ Beep and lights up Red and Green LEDs if passed

...........................................................................Stop if failed

4. Turn on Green LED to indicate successful test.

If all of the above occurs, the test has been successful.

5. Check GPS circuitry and data ....................... Beep and lights up Red and Green LEDs

Approximately 2 to 3 seconds after the Green LED if

passed (GPS location data has been loaded)

4.7.2 It is strongly recommended to test the ThunderBird SSAS on a monthly basis.

4.8 External GPS interface

4.8.1 External GPS interface requirements:
GPS receiver must provide location information according to the following requirements:

• NMEA 0183, Version 1.5 or higher

• Baud rate: 4800

• Talker device identifier: GP (GPS Receiver)

• Sentence format: GGA (GPS Fix Data)

In order to be compatible with the ThunderBird SSAS an external

Y1-03-0180 Rev. D 11

4.8.2 Using the GPS interface:
beacon will store GPS data for incorporation into the emergency message, which is transmitted to the
satellite. This can provide more accurate positioning data to the national authority and may lead to faster
response. Since the last valid GPS position data is always kept in the memory of the beacon, the user
should take care to make sure that the GPS position data stored is accurate. This can be accomplished by
two methods: First, by always leaving a properly functioning GPS receiver connected to the beacon before
activation. Second, by connecting a properly functioning GPS receiver with a valid position fix to the
beacon and allowing sufficient time for the beacon to acquire valid position data from the GPS. This will
take a nominal 20 minutes if old GPS position data is stored in the beacon’s memory. If GPS data is not
stored, the beacon will acquire current data within a minute of being connected to a GPS with a valid
position fix. You can force the beacon to update its position at any time by initiating the beacon’s self-test,
see 4.8.3 and 4.8.4. If valid GPS position data is not available, it is preferable to reset the beacon with the
beacon’s default message (See Section 4.8.5).

4.8.3 Testing the GPS interface:
for the GPS receiver to acquire valid GPS position data (usually less than 1 minute; but it can take up to 30
minutes). Lift the thumb switch to the vertical (self-test) position and release. Your beacon will confirm that
it has acquired valid GPS data by emitting a beep along with a flash of the red and green LEDs. This will
occur approximately 2.5 seconds after the self-test.

4.8.4 Updating GPS position data:
GPS receiver, GPS position data is automatically updated about every 20 minutes, while valid GPS
position data is present. The operator can force the acquisition of new GPS position data, by executing
self-test of the beacon. This bypasses the normal, programmed, waiting time of 20 minutes for the
automatic update of GPS position data. Once the beacon has completed the self-test sequence by emitting
the beep and flash of red and green LEDs, as described in 4.8.3, the beacon will request and acquire new
position data from the GPS. This can take a nominal 15 seconds or up to one minute.

NOTE: When the beacon is not activated, GPS position data will be received and stored by the beacon

(No GPS position data updates will occur while the beacon is activated. However, subsequent
position information is determined by the COSPAS-SARSAT Satellite System as described in
Section 6.)

4.8.5 Position data set to default:
“default”. This “default” GPS position data indicates, upon activation, to the satellite system that the beacon
has no valid GPS position stored in memory. Once a functioning and compatible GPS receiver is properly
connected to the beacon, this “default” data will be replaced by valid GPS position data, as described in
the previous sections.

Position data will be reset to default by activating the beacon (by placing the thumb switch in the ready
position and then pressing one of the remote activation points) and then turning the beacon off by returning
the thumb switch to the off position. Once the beacon is in ON mode, it must be turned OFF within 45
seconds to prevent transmission of a live burst. Because the activation points must be remote from the
beacon, it is recommended that two people with 2-Way radios perform this procedure to prevent false
alarms.

NOTE: THIS BEACON IS AUTHORIZED FOR USE ONLY DURING SITUATIONS WHERE THE
SECURITY OF YOUR VESSEL IS UNDER THREAT OR HAS BEEN COMPROMISED AND POLICE
ACTION IS REQUIRED.

ALSO NOTE: The action of turning the beacon ON and then OFF clears any stored GPS position data.

SECTION 5 - CARE AND MAINTENANCE

5.1 At least every ninety days, the mounting bracket, antenna and beacon should be inspected for
deterioration and/or buildup that may affect the function of the beacon or it’s mounting.

Also carefully inspect the beacon case for any visible cracks. Cracks may admit moisture, which could

falsely activate the beacon or otherwise cause a malfunction. Any cracking observed should be
immediately referred to ACR for evaluation, (1-800-432-0227 Ext. 112).

Once a compatible operating GPS receiver is connected to the beacon, the

Carefully inspect the antenna for excessive corrosion of metal parts and visible cracks on the plastic

housing. These could result in a malfunction of the antenna. Any of the above should be immediately
referred to ACR for evaluation. Antenna accessories and rebuild kits are available if the antenna should
be damaged. (See page 21 for more details).

5.2 Clean the beacon and the mounting bracket to remove residue buildups. It is recommended that the
mounting bracket be wiped with a damp cloth.

5.3 Check coaxial connector on cable from the antenna for tightness.

5.4 The battery (P/N 1096) must be replaced by the date indicated on the beacon. At each inspection, check
the time remaining until replacement is required. Battery should be replaced if the beacon has been
activated for any use other than the self test.

NOTE: There are no user serviceable items inside the SSAS. DO NOT OPEN THE SSAS UNLESS TO

DISABLE IN CASE OF FAULTY ACTIVATION.

Self contained long life batteries with a five-year recommended replacement cycle provide power. See

Factory Authorized Service Center for replacement.

Battery replacement includes: replacement of the lithium battery pack and proper disposal, replacing all o-

rings, testing the water seal and performing a full electrical diagnostic check.

Always refer all battery replacement and other SSAS service to a factory authorized service center.

Materials Regulations. They also meet the United Nations classification of lithium batteries for shipment as
“Non – Dangerous Goods”.

SECTION 6 – THE SEARCH AND RESCUE SYSTEM

6.1 General overview

SSAS beacons provide distress alerting via radio transmission on 406 MHz to satellites of the COSPAS-

SARSAT network. The ThunderBird SSAS can also transmit a distress alert to the GEOSAR network that
includes GPS latitude and longitude coordinates that are inputted through an I/R Interface that connects to
the data output of a GPS Receiver.

The message transmitted is unique for each beacon, which provides identification of the transmitter

through computer access of registration files maintained by the National Oceanic and Atmospheric
Administration or other national authority. Remember, if your beacon is not registered
Rescue (SAR) Authorities do not
about your situation (Refer to Section 1).

Once the signal (406 MHz) is relayed through the LEOSAR and/or GEOSAR network, SAR forces

determine who is closest, and then track the signal using the 121.5 MHz homing frequency for intermediate
and short-range location.

, Search and

6.2 Satellite detection

SSAS beacons transmit to the satellite portion of the COSPAS-SARSAT System. COSPAS-SARSAT is an

international system that uses Russian Federation and United States low altitude, near-polar orbiting
satellites (LEOSAR) that assist in detecting and locating activated 121.5/243 MHz beacons and 406 MHz
Satellite beacons.

COSPAS and SARSAT satellites receive distress signals from the SSAS transmitting on the frequency of

406 MHz. The COSPAS-SARSAT 406 MHz beacon signal consists of a transmission of non-modulated

Y1-03-0180 Rev. D 13

carriers followed by a digital message format that provides identification data. The 406 MHz system uses
Satellite-borne equipment to measure and store the Doppler-shifted frequency along with the beacons
digital data message and time of measurement. This information is transmitted in real time to an earth
station called the Local User Terminal (LUT), which may be within the view of the satellite, as well as being
stored for later transmission to other LUTs.

The LUT processes the Doppler-shifted signal from the LEOSAR and determines the location of the

beacon; then the LUT relays the position of the distress to a Mission Control Center (MCC) where the
distress alert and location information is immediately forwarded to an appropriate Rescue Coordination
Center (RCC). The RCC dispatches Search and Rescue (SAR) forces.

The addition of the GEOSAR Satellite system greatly improves the reaction time for a SAR event. This

satellite system has no Doppler capabilities at 406 MHz, but will relay the distress alert to any of the LUT
stations. When there is GPS data included in the distress message, SAR authorities instantly know your
location to within 110 yards. This speeds up the reaction time by not having to wait for one of the LEOSAR
satellite to pass overhead. Because most of the search and rescue forces presently are not equipped to
home in on the 406 MHz Satellite beacons signal, homing must be accomplished at 121.5 MHz.

6.3 Global Positioning System (GPS)

The GPS system is a satellite group that enables a GPS receiver to determine its exact position to within
30m anywhere on Earth. With a minimum of 24 GPS satellites orbiting the Earth at an altitude of
approximately 11,000 miles they provide users with accurate information on position, velocity, and time
anywhere in the world and in all weather conditions. The ThunderBird SSAS stores this data into its
distress transmission allowing search and rescue forces to narrow the search into a very small area and
thus minimize the resources required and dramatically increases the effect iveness of the overall operation.
