GNSS receivers meet the needs of precise positioning at sea, compatible with RTX, PPP and RTK correction networks. 

Compact and reliable, equipped with radio or modem modules, depending on the model, they are multi-constellation and multi-frequency and have a PPS output.

They allow to obtain the position but also the heading. We offer a complete range of receivers and our experts will help you choose the most suitable solution for your applications.


Our Range of GNSS Receivers

Anchor 1


The SPS855 GNSS receiver is the modular TRIMBLE receiver which is used as a base station and is capable of transmitting to all types of antennas.
