GPS Interface
The MultiModem EDGE, GPRS, or CDMA wireless modem with GPS incorporates an internal Trimble
Lassen
iQ GPS module providing 12-channel GPS functionality. It delivers complete position, velocity, and time (PVT)
solutions making it ideal for real-time vehicle tracking, navigation, and fleet management applications.
The GPS functionality supports four of the most popular protocols: NMEA 0183, DGPS (RTCM), TSIP (Trimble
Standard Interface Protocol), and TAIP (Trimble ASCII Interface Protocol) and provides dual sensitivity modes
allowing it to automatically switch to higher sensitivity when satellite signals are weak.
The MultiModem EDGE, GPRS, or CDMA wireless modem with GPS utilizes an RS-232 interface. The GPS
information is received on a secondary serial port and can be used for in-vehicle navigation. In addition, the data
can be sent through the wireless modem to a central, real-time tracking server via SMS or GPRS.
The MultiModem EDGE, GPRS, or CDMA wireless modem provides flexibility to allow third party GPS
applications and Application Service Providers (ASPs) the ability to customize their software to work with the
wireless modem hardware.
