Trimble SPS Series Site Positioning toolsTrimble says new firmware for its Global Positioning System (GPS) receivers will speed initialization and improve receiver performance in areas with limited satellite reception to benefit contractors using GPS receivers in the Trimble Site Positioning Systems (SPS) series. When real-time-kinematic correction signals are intermittent or marginal, the new RTK engine improves estimate precision. It allows a Trimble GPS receiver to continue working at reduced accuracy even after an RTK signal is interrupted. Trimble GPS receiver firmware 4.0 utilizes a new proprietary protocol, CMRx, for corrections transmitted by a GPS base station. The ability to track more satellite signals maximizes the use of all available satellite signals and constellations at both the base station and the rover for increased uptime.
