Attention:
Trimble 1 and Trimble 2 GPS Receivers are operated by ship's command only.
The sensor is essential device providing position data for a large number of scientific devices. Most sensors do not directly receive positions from GPS sensor but from motion sensor Hydrins.
The system TRIMBLE 1 / HYDRINS 1 and TRIMBLE 2 / HYDRINS 2 are alternatively sending positions to the customers. DShip is logging positions from both GPS receivers in parallel.
Summary
The Trimble R750 is a combined radio and GPS receiver. It uses all currently available satellite signals including L1, L2 and the GPS modernized L2C code.
