Introduction
The GPS-721U-MRTU(-UTA) is a GPS/GLONASS receiver module, features high sensitivity, low power consumption and ultra small form factor with DCON, Modbus RTU and NMEA protocols. It provides you with superior sensitivity and outstanding performance even in the harshest environment. The GPS-721U-MRTU(-UTA) 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. It can also be applied in Automotive navigation, Personal positioning and navigation, Marine navigation, Satellite time correction and etc. You can use DCON Utility Pro software to select the appropriate GNSS system and then power it on and off to take effect.
