Trimble SPS851

Trimble's SPS851 Modular GPS Receivers are ideal for semi-permanent or permanent base station setups. 

The SPS851 Modular GPS Receiver is designed to receive current and future satellite signals. This receiver supports GPS modernization through support of L2C code and can be upgraded to receive GLONASS or L5 GPS signals, protecting your investment well into the future.  

The SPS851 contains a builtin powerful web server component that enables increased operational efficiency and flexibility. Using this Internet-enabled base station allows for remote configuration and monitoring, eliminating the need for time-consuming and costly visits to the base station to set up each day or diagnose issues that may arise. Internet base stations can provide corrections to multiple rovers in the same vicinity or provide corrections to cell phone enabled rovers in areas of radio blackout.
