Product description

The QUAKE QLOCATETM is an Iridium Short
Burst Data (SBD) transceiver available in two
standard configurations: one is a simple SBD
transceiver, and the other one is also integrated
with a GPS/GLONASS receiver. It is an
efficient, satellite add-on solution that allows
effortless connection to Iridium’s satellite
network. The QLOCATE can switch smoothly
between satellite and GPS mode.

A unique option of the QLOCATE is its built-in,
state-of-the-art GPS/GLONASS receiver that
allows system integrators to use a single,
dual-mode, L-Band antenna for both
GPS/GLONASS and Iridium SBD. This
eliminates the need for a second antenna and
for external global positioning modules.

The QLOCATE’s simple installation and
integration make it optimal for any developer
who is facing an accelerated time-to-market
requirement.

1 Introduction

Scope

This data sheet contains a description of the operation, specifications and characteristics of the QUAKETM
QLOCATE, which is an Iridium Short Burst Data (SBD) transceiver integrated with GPS/GLONASS.

Iridium

Iridium’s network is a global satellite data solution, with complete coverage of the earth (including
continental, ocean, and Polar Regions). Iridium delivers low latency, essential communications services
to and from remote areas where no other form of communication is available. The Iridium constellation of
66 low-earth orbiting (LEO) satellites operates as a fully meshed network. It is one of the largest
commercial satellite constellations in the world. The Iridium service is ideally suited for industries such as
maritime, aviation, government, emergency/humanitarian services, mining, forestry, oil and gas, heavy
equipment, transportation and utilities.

Short Burst Data (SBD)

Iridium Short Burst Data (SBD) Service is an efficient network protocol designed for shorter-sized data
messages that can be economically sent via Iridium Circuit Switched Data Services. SBD uses a
proprietary network protocol to transfer data messages to and from the remote terminal. Currently, the
QLOCATE supports only Iridium’s SBD service.

It is possible to send Mobile Originated (MO-SBD) and Mobile Terminated (MT-SBD) messages.
Message sizes for:

• MO-SBD are between 0 and 340 bytes;

• MT-SBD are between 1 and 270 bytes.

These specifications reflect QLOCATE’s design for

use with a passive antenna.

• Iridium specifies an antenna with 3dBi Gain,

RHCP polarization, 50 Ω nominal impedance

and 1.5:1 VSWR. Several vendors have patch
antennas that will meet this specification, and
are certified by Iridium to operate on their
network.

• If the user’s design requires use of an active
antenna for the GPS, the design of their
application will require additional circuitry.

2.1 Operating modes

2.1.1 Power OFF

• The QLOCATE with GPS/GLONASS is no longer functional when external power is removed.

• The QLOCATE without GPS/GLONASS can be controlled by the ON/OFF pin (5) when external

power is applied. The modem is no longer functional when external power is removed.

2.1.2 Power ON

• The QLOCATE with GPS/GLONASS is ON when input voltage to the modem is applied.

• For QLOCATEs without GPS/GLONASS, the ON/OFF signal must be asserted when power is

applied in order to turn on the modem.

2.1.2.1 RF Receive/Idle

The QLOCATE alternates between the idle state and receiving receive bursts.
In Receive mode:

The RF and digital signal processor portions of the modem are active, and GPS is not active.
In Idle mode:

The required input power along with the assertion of the ON/OFF signal (pin 5) must not be present; GPS
will be active.

2.1.2.2 Transmit

The QLOCATE is sending an outgoing SBD message. The QLOCATE may also query the Iridium system
in a search for incoming messages (see AT Command Set manual for sequence and commands and
section 8 - AT Command Set Description).

2.1.3 Switch from Iridium to GPS/GLONASS

For QLOCATEs with GPS/GLONASS:
The QLOCATE alternates between Iridium and GPS/GLONASS. To enter GPS/GLONASS mode, the

required input power along with the ON/OFF signal (pin 5) must be low. The NMEA data will
subsequently be sent to the Rx port.

Ensure that all power pins and ground pins are connected externally.

3 Input/Output interfaces

3.1 Interface connector

The QLOCATE has a 20 pin interface connector. The pinout is shown in Table 3-1 and the limits for the
digital signals are listed in Table 3-2. The connector contains several supply grounds; all supply and
supply grounds must be connected to the power supply to ensure that the current on any one pin is
limited. Cross-talk is reduced through the use of multiple signal grounds.

The interface connector provides the following connections to the QLOCATE:

• DC power supply input

• Power on/off control

• Serial data interface

• Network available output

• Supply power indicator output

3.1.1 Type

The connector on the QLOCATE is a Samtec low-profile header connector, part number FTSH-110-01-L­DV. This connector makes a stackable board-to-board configuration possible, enabling connection to the
host system motherboard. A suitable motherboard female socket that matches this connector is the
SAMTEC header, part number CLP-110-02-L-D. See the Samtec website at: http://www.samtec.com for
more information on this connector.

3.1.3 Power consumption

Power consumption is dependent on the mode in which the QLOCATE is operating. The amount of time
the QLOCATE spends in any of its modes will determine the overall current draw.

The current draw specifications detailed in Table 3-3 apply to DC power measured at the QLOCATE’s
interface connector input and not at the output of the power supply. If the power supply cables are
excessively long a voltage drop can occur that is sufficient to cause the voltage to be out of specification
at the physical power supply input to the QLOCATE.

In-rush limit refers to the impedance of the modem, which is very low when it is
unpowered. When power is supplied from an unlimited supply, the instantaneous
current can exceed 4 Amps which can cause damage to the modem. This can be
limited in several ways, included using a supply that cannot provide more than 4 Amps
instantaneously; or providing some series inductance/resistance to the supply lead.

The following must be guaranteed by the external power supply:

• The supply voltage droop over for a 8.3ms burst of 1.5A current should not be more than 0.2 V.

• The in-rush current should be limited to a maximum of 4 Amps

• The power source shall provide for over current protection in case of device malfunction.

• The supply noise should be less than the limits in the following profile:

• 100 mVpp from 0 to 50 kHz

• 5 mVpp at 1 MHz measured in 50 kHz bandwidth

• 10 mVpp at 1 MHz measured in 1MHz bandwidth

• 5 mVpp above 5 MHz measured in 1 MHz bandwidth.

The behavior of +CIEV:1 is identical to that of the Network Available output.

3.2 Serial data interface

The serial data interface is an RS-232 9-wire interface at 3.3V digital signal levels (LVTTL) over which the
QLOCATE and the customer solution transfer commands, responses, and SBD message data. In using
this interface, the QLOCATE behaves as a DCE (Data Communication Equipment), and the customer
solution behaves as a DTE (Data Terminal Equipment).

• If RS-232 voltage levels are needed, the customer solution must include an LVTTL/RS-232
level-shifter.

• Autobaud is not supported. The baud rate can be set via the AT+IPR command. The default
rate is 19200 bps.

The QLOCATE’s serial interface supports the control signaling of a 9-wire interface by default for those
host applications that require it. However, the interface can also be configured for 3-wire operation – in
which only transmit, receive and ground signals are used – with no detriment to functionality/performance.

See the ISU AT Command Set for more information.

3.3 Network Available output

Network Available is a digital output that can notify an application that the QLOCATE has visibility to the
Iridium satellite network. This feature is helpful when the movement of the QLOCATE reduces the
amount of time that it has a clear line of sight to the satellite. If the customer solution includes this logic
output in the application decision logic, battery life can be preserved by thereby reducing the number of
attempted transmissions.

Network Available means only that the QLOCATE can successfully receive the Ring Channel (namely, it
has an Iridium satellite in view). It is not a guarantee that a message can be successfully sent. The
Network Available state is evaluated every time the Ring Channel is received, which is typically every 4
seconds if the Ring Channel is visible. If the Ring Channel is not currently visible, the update time can
take as long as 2 minutes, depending on how long the lack of satellite visibility existed. The update time
varies because the QLOCATE attempts to conserve power by increasing the Ring Channel search
interval as long as the satellites are not in view. Every time a ring search fails, the time to wait is
increased and eventually limits at 120 seconds.

If Network Available is currently off, the customer solution may still attempt an SBDI[X] session. This will
force the QLOCATE to look for the Ring Channel immediately and, upon finding it, to attempt to send the
message. In this case, Network Available will not come on immediately. The Network Available does not
turn on while in a +SBDI session. It will, however, turn on 4 seconds later due to the assumption that the
Ring Channel is present. After the SBD session completes, the QLOCATE performs a new Ring Channel
search, at the end of which Network Available is turned on. This can take between 4 and 12 seconds.

The wait time between search windows is reset to 4 seconds every time a search succeeds. Otherwise, it
continues to increase. Therefore, if the +SBDI attempt fails to find the Ring Channel, the search window
does not reset to 4 seconds.

3.4 DC supply indicator output

A DC supply indicator signal is provided which could be used directly for driving an LED to provide a
visible indication that the QLOCATE’s supply is on. Alternatively, the output signal could be used in
application logic to determine whether the internal transceiver power supply is on.

For safety reasons, the RF connector on the QLOCATE is intended for an inter-board

connection to the host system motherboard and should not be directly connected to an
external antenna cable or cable distribution system. Paragraph 7.3 of EN60950-1:2006
safety standard requires that users are protected against high voltages that might
appear on these cables. This can be achieved either by inserting a high-voltage
isolating capacitor in series with the signal or by grounding the shield of the coaxial
cable. The MMCX connectors have limited voltage capacity; therefore, protection

needs to be provided on the developer’s motherboard. Developers are encouraged to

review the EN60950-1:2006 standard for additional details.

4 RF interface

4.1 Connector types

When mating to the QLOCATE RF connector, use MMCX male connectors from SAMTEC, part number
MMCXP-P-H-ST-TH1. This is a thru hole printed circuit mount connector with the correct mechanical
spacing to allow the QLOCATE to fit flush on the motherboard.

Additional information can be found at: http://www.samtec.com.

4.2 ANT connector

The main RF connector for the QLOCATE is the antenna connector. This provides the RF connection
between the QLOCATE and the host system motherboard.

4.2.1 Antenna characteristics

The QLOCATE should be connected to an Iridium-band antenna with the following antenna connector

7 Operation

7.1 Installation recommendations

• It is best to connect the UBATT (-) to chassis ground rather than to the (-) battery terminal.

• The input voltage range is: 5 ± 0.5 VDC.

• In order to protect wires installed within the engine compartment or along the undercarriage,

ensure that all wires are wrapped with wire loom.

7.1.1 Mounting

Figure 7-1: QLOCATE mounting example

Mounting notes:

1. The example of a host system motherboard footprint in Figure 7-1 is shown for illustrative purposes
only. The host system may require a different PCB layout or mechanical arrangement.

2. The QLOCATE is designed to be incorporated within a host system. It is therefore important that the
antenna or cable distribution system that feeds the host system be terminated in a robust RF
connector that is suitable for the end-application.

3. Safety isolation requirements for external antennas or cable distribution systems should also be taken
into account when designing the motherboard. A suitably safe design for the RF connections should
be incorporated into the host system motherboard, ideally using a chassis-bonded ground connection
to the antenna cable shield.

4. The surface below the modem should be a conductive ground plane to ensure that the modem bonds
to the motherboard ground system, thereby reducing the possibility of radiated emissions. This also
requires that the mounting screws be properly tightened to 7 pound-inches of torque.

Although the modem dissipates very little power, its use in ambient temperatures in
excess of 60 deg C will make the caseworks notably hot.

5. The modem is to be installed in a “service access only” area not accessible by untrained personnel
and must be protected from inadvertent contact.

WARNING
HOT SURFACE
DO NOT TOUCH

7.2 Basic operation

• The QLOCATE with GPS/GLONASS contains both a GPS module and an Iridium satellite module.
Only one module is utilized at a time. Pin 5 is the line that controls which module is being used.

• For QLOCATEs without GPS/GLONASS, power must be applied and pin 5 should be asserted to turn
on the QLOCATE, and de-asserted to turn off the QLOCATE.

7.2.1 Iridium satellite

When there is potential on pin 5 (3.3V), the Iridium module is utilized. The default baud rate for the
Iridium module is 19200. From a terminal window set at 19200, basic AT commands can be used to
control the module. Section 8.1 - Example: Send and receive a message outlines the steps to power on
and send or retrieve a message.

7.2.2 GPS option

When there is no potential on pin 5 (0V), the GPS module will be utilized rather than the Iridium module.
The default baud rate for the GPS module is 9600. Through a terminal window the GPS NMEA strings
can be seen. The module automatically starts a GPS read to acquire a fix when utilized.
