GPS RTK Install with Pulse Trigger Module in the Application Research of Multibeam System

This paper mainly discussed whether the modified synchronous signal of GPS emission could be recognized by R2 SINC 2024, whether multi beam system could use the GPS RTK high precision positioning technique without tidal operations. By modifying the LEICA GPS, joining the PPS second pulse transmitting module, synchronous signal were provided for multi-beam system. By analyzing the results of field experiments, modified LEICA GPS PPS second pulse transmitting module can be identified by R2 SINC 2024, at the same time, because of the high precision positioning information using the GPS RTK output, the quality of multi beam system bathymetric data was significantly improved.
