DUAL FREQUENCY GNSS
AccuTrace uses differential GPS L1/L2 and GLONASS to provide sub-centimeter accuracy on quasi-static platforms, and sub-decimeter accuracy on dynamic platforms.
AccuTrace fuses multi-frequency multi-constellation measurements using seamless filtering algorithms to improve reliability and accuracy.
AccuTrace is a new Differential Global Navigation Satellite System (DGNSS) capable of providing sub-centimeter positioning accuracy for quasi- static scientific, mapping, and survey applications. It autonomously finds the surrounding Continuously Operating Reference Stations (CORS) stations.
AccuTrace is originally developed for National Oceanic and Atmospheric Administration, NOAA, under a Phase-II Small Business Innovative Research (SBIR) contract.
AccuTrace will be used by NOAA in its National Water Level Observation Network (NWLON) service, that monitors the levels in all water surfaces in the US. It can also be used for many other high-precision surveying, mapping and structural monitoring applications.
