WARNINGS
GOOD JUDGEMENT
This product is an excellent navigation aid and communications
tool, but does not replace the need for careful orienteering and
good judgement. Never rely solely on one device for
navigating.
USE CARE
The Global Positioning System (GPS) is operated by the U.S.
Government, which is solely responsible for the accuracy and
maintenance of GPS.
The accuracy of position fixes can be affected by the periodic
adjustments to GPS satellites made by the U.S. Government
and is subject to change in accordance with the Department of
Defense civil GPS user policy and the Federal Radionavigation
Plan.
USE CAUTION
Accuracy can also be affected by poor satellite geometry.
When the accuracy warnings appear on the screen, use the
data with extreme caution.
USE PROPER ACCESSORIES
Use only Magellan cables and antennas; the use of nonMagellan cables and antennas may degrade performance or
damage the receiver, and will void the warranty.

RADIATION WARNING
Although no single value of “safe
radiation level” has been agreed upon
by all countries, the American National
Standards Institute (ANSI/LEEE C95.1
- 1992) recommends that people
should not be exposed to radiation
stronger than 1 milliwatt per square
centimeter at the frequencies used in
the Magellan GSC 100. Due to the
GSC 100 transmission times being
very brief, the amounts are well within
acceptable limits as set forth by the
American National Standards Institute.
LIGHTNING WARNING
Due to the extension capability of the ORBCOMM telescopic
antenna located on the GSC 100, it is strongly advised that
operations of the GSC 100 cease when thunderstorm or
electrical storm conditions are present.

INTRODUCTION
Welcome to the GSC 100
Congratulations on your purchase of the Magellan GSC 100
Satellite Communicator, the world’s first hand-held global
satellite communicator. You now have the ability to send and
receive GlobalGrams, e-mail messages, to and from anywhere on
Earth. Because the GSC 100 uses standard e-mail protocols,
sending and receiving GlobalGrams is easy. Communicate to any
e-mail (Internet, X.400) address or another GSC 100. And, with
its integrated GPS capability, the GSC 100 not only lets you know
where you are, it guides you anywhere you want to go. You can
identify your position, plot and track your course or store
waypoints. Your GSC 100 will get you anywhere and back again
at the push of a button. You can also relay your position to
anyone, anywhere - no matter how remote you may be - with a
GSC 100 GlobalGram. And with its rugged, splashproof
construction, the GSC 100 is ready for action, no matter where
your adventures may take you.
To help you get started using your new GSC 100, turn to the
section titled “Getting Started.” This quick-start session will
have you sending and receiving GlobalGrams as well as
recording landmark locations and navigating in no time at all. It
is important to note that, prior to use, you must activate the unit
within the ORBCOMM network, as they are the service provider.
Activation Instructions have been provided to assist you in
activating your GSC 100. A Quick Reference Guide has been
provided to assist in operating the unit while making your way
outdoors. After you’ve learned the basics, the rest of this manual
will give you detailed information about all the features and
functions of your GSC 100 Satellite Communicator. A Reference
Section, Troubleshooting, and Appendix, with Glossary, are
included as well.

Magellan GSC 100 Global Satellite Communicator 3
Messaging Activation
Prior to use, your GSC 100 unit must be activated within the
ORBCOMM network by your local service provider. A set of
Activation Instructions have been included with your GSC 100 to
guide you through the activation process. Included in the
Activation Instructions are the instructions, forms, payment
information and a list of contacts. Activation allows your service
provider to open an active account so that you can begin to send
and receive GlobalGrams using your GSC 100. During the
activation process you will receive a unique e-mail address for
your GSC 100. Future system enhancements, or issues, will be
communicated to you to keep you up and running. Activation
procedures differ from country to country and should be verified
by your local service provider.
During the activation process you will need the serial number for
your unit. The serial number can be found on the outside of your
GSC 100 box; on a sticker on the inside of the battery door; on
the COPYRIGHT screen displayed during start-up; or on the
ABOUT screen accessed from the GENERAL SETUP menu.
Also, prior to using the messaging capabilities, you must initialize
your GSC 100’s GPS receiver. This will allow the unit to acquire
a position and find the ORBCOMM satellites needed to transmit/
receive GlobalGrams as well as display the ORBCOMM satellite
schedule.
To legally operate a GSC 100, it is the responsibility of the user
to obtain permission from the local telecommunications
regulatory authorities of the country you are operating within.
Using your GSC 100 in any country without permission causes
you to run the risk of confiscation of your unit or legal action
from local authorities. Normal practice for taking
telecommunication equipment into another country is to apply
for a license prior to travel. If a license has not been obtained
before travel, the equipment may be put into storage by local
authorities until such time as a license is obtained.

out the battery pack and release the snap on the side of the
battery pack clip, shown above. Pull the GSC 100 and the
battery pack clips apart. You will have up to fifteen minutes to
replace the battery before internal memory (messages,
addresses, waypoints and routes) is lost. Take a replacement
NiCad battery pack, available from Magellan, and clip it onto
the GSC 100 battery clip and close the battery door.
Charging the Battery
When the battery is low, depicted by the low battery icon shown
in the status bar, you will need to recharge it for further use. To
charge the 9.6 VDC Rechargeable NiCad Battery Pack, supplied
with your GSC 100, you will need to connect the data power
extension cable to the RS-232/Power port located on the side of
the unit. Then connect the AC power cable into the data power
extension cable and plug into external power. You will be able to
operate the unit while the battery is charging although it will take
longer to charge. It is recommended that you charge the battery
while you are not using your unit to assure that the battery pack
gets fully charged. It will take 6 hours of un-interrupted charging
to fully recharge the battery pack.
It is imperative that, when connecting external power to your
GSC 100, the connectors are properly aligned so as not to
damage the pins.
Magellan GSC 100 Global Satellite Communicator 9
Only the Magellan-supplied 9.6 VDC Rechargeable NiCad
Battery Pack will work with your GSC 100. Do not attempt to
use any other batteries as they may not work with your unit and
any damage caused by their use will void the warranty.
Turning the Receiver “ON” & “OFF”
To turn the GSC 100 “ON”, press the POWER key and wait for
the unit to scroll through the start-up screens.
To turn the unit “OFF” press the same POWER key. This will
start a shutdown sequence that counts down the seconds until the
unit actually turns “OFF.” To immediately turn the receiver
“OFF” press the POWER key again. This bypasses the
countdown and the unit turns “OFF” immediately.
GPS Initialization
When you are using the unit for the first time, move the unit 300
or more miles without the unit taking a position fix or perform a
system reset, you will need to initialize the GSC 100 with the
current location, elevation, local time and date information. This
is because the constellation of 24 GPS satellites circling the globe
are in constant motion and before your receiver can tell you
where you are, it needs to know roughly where the satellites are,
relative to itself. It does this with the use of an almanac where it
has stored in memory a general location, a time and a date. The
almanac tells the receiver which satellites will be in view. Using
the location and time you enter, the receiver can quickly find
satellites and calculate your position sooner. Without
initialization, the unit will take a longer period of time to provide
position information or locate GPS or ORBCOMM satellites.

Daylight Savings time does not affect the time in your unit, as
long as you take a position fix after entering your local time.
This allows the satellite to correct any time differences.

When the time is correct, press
ENTER. Your receiver requires
just one more piece of information,
the date. Use the ARROW KEYS
and the numeric keys to input the
correct date. Press ENTER.
Once you have completed the
Initialization of the GSC 100 you
will be brought back to the MAIN
MENU. Time and date will not
be displayed if the receiver has
already acquired a satellite and
received that information from it.
Proper Handling - Signal Reception
Since the GSC 100 receives information it needs from satellites
orbiting the earth, the antennas need to have a relatively
unobstructed view of the sky.
Blocked or Partially Blocked View of
the Sky. Physical obstructions will
block satellite signals from reaching the
receiver, as may be the case with the
cliffs in the picture. If you are unable to
get a position fix, send or receive
messages, move the receiver so it has a
clearer view of the sky.
Clear View of the Sky. The receiver
now has a clear view of the sky in all
directions, allowing it to choose from all
of the satellites currently available. Do
not attempt to use the unit in metal or
concrete structures as the signals will be
obstructed.

The GSC 100 is designed to fit in your hand. The unit can also be
mounted in a stand that can be purchased from your local GSC
100 dealer. Hold the receiver with the antenna extended upwards
toward the sky and the unit comfortably in your hand and slightly
away from your body so that you can see the screen.
Do NOT place metallic decals or labels over the antenna portion
of the receiver. Drastic reductions in signal levels can
significantly decrease the GSC 100’s signal reception.
If you are sending or receiving GlobalGrams, the telescopic
antenna, located on the side of the unit, needs to be fully
extended. If you are using the unit to navigate, you do not
need to extend the telescopic antenna.
Due to the extension capability of the ORBCOMM telescopic
antenna located on the GSC 100, it is strongly advised that
operations of the GSC 100 cease when thunderstorm or
electrical storm conditions are present.
Best reception will occur when the unit is operated away from
noise sources such as high voltage power lines and older
internal combustion engines. If your unit is experiencing
difficulty in establishing contact with satellites, move away
from any such noise sources that may be present. Also, due to
the radiation pattern of the ORBCOMM telescopic antenna, you
may have better transmission quality if the antenna is held at an
angle to the transmitting ORBCOMM satellite.
14 Magellan GSC 100 Global Satellite Communicator
System (SYS) Modes
This section outlines the different modes of operation used in the
GSC 100. There are three system, or operating, modes: AUTO
MODE, GPS MODE and ORBCOMM MODE.
GPS Mode
The GPS mode should be engaged when the NMEA port is in use,
for external marine products or an autopilot, where a constantly
updated position fix is necessary. All other GPS functions can be
utilized while in the AUTO mode. The unit will not transmit or
receive messages while in this mode. In GPS mode, if your
receiver is not communicating with a GPS satellite and your time
and postion coordinates are incorrect, your ORBCOMM satellite
pass schedule will be inaccurate.
ORBCOMM Mode
When in the ORBCOMM mode, your receiver will continuously
listen for ORBCOMM satellites regardless of the satellite
schedule. ORBCOMM mode should be used when it is
imperative that you send or receive GlobalGrams. If there is a
scheduled pass at a certain time and you have a GlobalGram you
need to send, or a GlobalGram you are expecting to receive, you
would engage the ORBCOMM mode to ensure delivery or receipt
of these messages. While in ORBCOMM mode, position
information and satellite schedule are based on the last calculated
satellite fix. GPS or AUTO modes need to be engaged to
continuously update the position of your receiver.
AUTO Mode
The AUTO mode is the default operational mode as well as the
recommended mode of operation. In AUTO mode, if you do not
have any GlobalGrams queued or are not requesting messages,
the unit will operate in GPS mode. If an ORBCOMM satellite
comes into view and you have a GlobalGram queued, or have
Magellan GSC 100 Global Satellite Communicator 15
Before you can use the ORBCOMM messaging functions, you
must first complete the Activation Procedures using the
Activation Instructions that came with your GSC 100. If you
have not received these Activation Instructions, contact
Magellan Customer Service at (800) 707-9971.
activated the request messages function, the GSC 100 will
automatically switch to ORBCOMM mode, perform the
necessary transmit/receive functions, then switch back to the GPS
mode after complete or when the ORBCOMM satellite is no
longer in view. The mode icon will change between current
operational modes as operation dictates. You will be able to use
the ORBCOMM functions and still allow the unit to update
important position information needed to generate ORBCOMM
satellite schedules. Conversely, in AUTO mode, if your receiver
is not communicating with a GPS satellite and your time and
postion coordinates are incorrect, your ORBCOMM satellite pass
schedule will be inaccurate.
Creating a GlobalGram
With your GSC 100 you have the ability to send and receive email-type messages, or GlobalGrams, from anywhere in the
world. In order to transmit a GlobalGram your unit must
have a clear view of the sky and the ORBCOMM antenna
must be fully extended and your unit in either ORBCOMM or
AUTO mode. This section helps you get started sending
GlobalGrams with your GSC 100. The REFERENCE section of
this manual contains greater detail.

A STORE & FWD GlobalGram is sent when your GSC 100 is
transmitting to an ORBCOMM satellite that is not in direct
communication with an ORBCOMM Ground Earth Station.
This will be reflected by the presence of a broken double arrow
icon displayed in the status bar at the top of the screen when
you are outdoors and a satellite is in view. You can only send a
STORE & FWD GlobalGram to one speed dial address. See
the REFERENCE section for message constraints, as well as
instructions on SENDING STORE & FWD
GLOBALGRAMS.
A STANDARD GlobalGram is sent when your GSC 100 is
transmitting to an ORBCOMM satellite that is in direct
communication with an ORBCOMM Ground Earth Station.
This will be reflected by the presence of a double arrow icon
displayed in the status bar at the top of the screen. For a
complete description of all the icons displayed in the status
bar, please refer to the ICONS section of this manual. You
have the ability to send a STANDARD GlobalGram to seven
recipients maximum, both primary and carbon-copy recipients
combined.

Receiving a GlobalGram
In order for you to receive a GlobalGram with your GSC 100, you
must request your unit to check for messages. Your unit must be
in either AUTO or ORBCOMM mode, with a clear view of the
sky and the ORBCOMM antenna fully extended, in order to
receive a transmission from an ORBCOMM satellite.
To receive GlobalGrams from a
satellite you must first request your
unit to CHECK MESSAGES. Do
this by pressing the MNU key from
the MAIN MENU or the MESSAGE
LIST, which will bring up a pop-up
menu with the options of CHECK
MSGS, MAILBOX, CONTRAST
or SYS MODE. Use the UP/
DOWN ARROWs to highlight
CHECK MSGS and press ENTER.
This sends a request to the satellite
for any messages it may have
received. Your GSC 100 will send
all queued messages prior to
checking for any incoming messages. When you are
receiving a transmission from a satellite, a double arrow icon
will be displayed at the top of your screen. Any attachments to
incoming GlobalGrams will be stripped out prior to receipt.
Upon receipt of a GlobalGram, an envelope icon will appear at
the top of the screen. To view this message, return to the
MESSAGE LIST by pressing the MSGS softkey while at the
MAIN MENU. The message you received will be preceded by
the envelope icon. Use the UP/DOWN ARROWs to highlight
the message and press ENTER. This opens up the message for
you to read and changes the icon in front of it to an open
envelope icon, while the envelope icon on the top of the screen
disappears. Use the UP/DOWN ARROWs to scroll through
the message.
