Description
Ultra services are based on Precise Point Positioning (PPP), a technique where all GPS system errors are removed or minimised by direct calculation, precise modelling or estimation. PPP isn’t dependent on the location of reference stations, so it’s able to provide position accuracy, regardless of location. To carry out PPP, real-time corrections are derived from the JPL Orbit and Clock Determination System (OCDS) which uses data from JPL reference stations.
Ultra can be purchased as a stand-alone service, but most often is purchased as a complementary service to Apex to ensure operation redundancy.
