MSATe Mobile Satellite Radio
The MSATe Mobile Satellite Radio is a powerful communications tool that
works where you do. Designed for use on the Ligado MSAT Network,
the MSATe supports continent wide Push-to-Talk (PTT), Voice and Data
communications. In addition, the MSATe offers GPS capability and flexible
interconnectivity to a variety of third-party Interoperability Devices,
extending the reach of traditional Land Mobile Radio technology.
MSAT Push-To-Talk (PTT) Dispatch Radio Service
MSAT PTT Dispatch Radio is a real-time, voice-based service that
provides point-to-multipoint and point-to-point communication at the
push of a button, simply, quickly and reliably. The service is a cost-
effective alternative to installing, maintaining, and relocating land-based
two-way radio communication systems.
MSAT Telephony Voice
MSAT Telephony Voice service makes sending and receiving voice calls as
easy as using any regular phone. Each MSATe has a local 10-digit number
and can dial normally to reach any phone anywhere in the world. The
MSATe is Government Emergency Telecommunications Service (GETS)
compatible.
MSAT Tracking
MSAT Tracking enables the transmission of MSATe GPS coordinates
whenever a user pushes the radio’s PTT button, and at one-minute
intervals during a telephone or data call. In addition, a dispatcher or fleet
manager can poll a subscribing MSATe radio for location information
anytime the unit is powered on.
Introduction
Powered by the SkyTerra 1 satellite, the Ligado MSAT
services cover North and Central America, Northern South
America, the Caribbean, Hawaii, and coastal waters.

To enable the transfer of data, data calls are initiated from Data Terminal
Equipment (DTE) devices such as a PC connected to the serial port.
The DTE device sends standard AT modem commands to configure
and initiate the data transfer call; the handset will display the following
messages during data calls:
DATA CALL – when a data call is initiated by the radio
INCOMING DATA – when an incoming data call is received
DATA mm:ss – to display the elapsed time of the data call
Incoming data calls produce an audible ring on the handset.

During a data call (transfer of data):
• The user may press the END key to terminate a data call.
Normally, data calls are terminated via the attached DTE device
with AT commands.
• The GPS soft key can be used to turn the GPS position display on
and off.
• Pressing any other keys will produce an error tone.
GPS Position Reports
If GPS position reporting is enabled on the network, the radio will
transmit its position over the network when a data call is initiated and at
one-minute intervals during the call.
Note: GPS reports at one-minute intervals may be suppressed during
times when continuous user data is being transferred.
Error Messages
If the network does not respond to the radio during a call attempt,
“CALL FAILED” will be displayed on the handset and a “NO CARRIER”
message is sent to the DTE device. Check the signal strength and try the
call again.
If a call drops while in progress, for example because the signal is blocked
by a bridge or building, an error tone is generated, “LOST CALL” is
displayed on the handset and a “NO CARRIER” message is sent to the
DTE device. Move away from the obstruction and try the call again.

Lock/Unlock Talkgroup
This is a soft key (Up-Arrow–SK3) option used to initiate the talkgroup
lock feature. The feature enables you to remain locked to a specific
talkgroup tag position in an idle state regardless of activity from other
downloaded talkgroups (subject to Network Monitor Codes).
When the handset is powered up and then goes into Idle State, SK3 is
the LOCK key. This indicates that the talkgroup feature is unlocked and
that pressing SK3 will initiate the lock.
To lock the specific talkgroup, press SK3. The SK3 indicator then changes
to UNLOCK, and appears at the top of the display.
To unlock the specific talkgroup, press SK3. The SK3 indicator then
changes back to LOCK, and the icon disappears.
When you are in a Dispatch Radio or Voice call, SK1 toggles the display of
GPS position.
If GPS information is currently displayed, press the SK1 to suppress the
display. The GPS display is then erased.
If the GPS information is not currently displayed, press SK1 to restore
the display.
PTT Operation
To initiate a Dispatch Radio call, press and hold the PTT key. The
CALLING and IN USE indicators then appear in the display followed by
USER ON, and an audible tone is emitted, indicating that you are the
current speaker.
When you release the PTT key, the VACANT indicator is displayed on
the handset, informing you that the channel is open to other talkgroup
members. If there is no response after a period of time, the talkgroup
will be dropped from the network. Control then reverts back to the idle
Dispatch Radio screen display.
