GPS-721-MRTU/GPS-721U-MRTU
|
The GPS-721-MRTU/GPS-721U-MRTU, a new GPS solution for Remote GPS Receiver module in ICP DAS, featuring high sensitivity, low power consumption and ultra small form factor with DCON, Modbus RTU and GPS protocols. This powerful item provides you with superior sensitivity and outstanding performance even in the harshest environment.The GPS-721-MRTU/GPS-721U-MRTU provides extra 1 channel DO and 1 channel PPS for users PPS signals can be used for precise timekeeping and time measurement. One can combine the PPS functionality with another as time synchronization source.
Therefore, the GPS-721-MRTU/GPS-721U-MRTU 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…
