Description
The GPS-721-MRTU, is a Remote GPS Receiver module, featuring high sensitivity, low power consumption and ultra small form factor with DCON, Modbus RTU and GPS protocols. This powerful unit provides superior sensitivity and outstanding performance even in the harshest environment. The GPS-721 provides an extra 1 channel DO and 1 channel PulsePerSecond output (the PPS signals can be used for precise timekeeping and time measurement). The PPS functionality can be combined with another as a time synchronization source.
Therefore, the GPS-721 can be a powerful GPS remote module as well as a general purpose GPS module with RS232 interface. It can also be applied in Automotive navigation, Personal positioning and navigation, Marine navigation, Satellite time correction and etc…
