Overview
The ATLAS PT GPS transponder is a rugged high-speed UHF/VHF data
modem with a built-in 12-channel GPS receiver. It can be set to output
½ to 5 watts of RF power, and can act as a transmitter or receiver (or
both) of GPS location data.
By default the ATLAS PT is configured as a Personal Locator. All
Raveon GPS tracking products are configured using the
GPS x
command. The ATLAS PT
comes configured from the factory as
GPS 8
.
Receiver is always off, serial baud rate is 38400, and battery-saving
features are enabled.
As well as sending position and status data, the ATLAS PT
also has a
radio modem with integrated RS232 interface. For privacy and security,
over-the air encryption is standard on every ATLAS PT
radio. For
network versatility, the ATLAS PT
incorporates a 16-bit identification
code, allowing up to 65,000 objects to be identified in one system. For
wide-area coverage, all ATLAS PT
transponders may be set to store-
and-forward messages from other ATLAS PT
transponders.
