GAPS provides users with accurate satellite positioning using a single GNSS receiver both in static and kinematic mode. Through the use of precise orbit and clock products provided by sources such as the International GNSS Service (IGS) and Natural Resources Canada (NRCan), it is possible to achieve centimetre-level positioning in static mode and decimetre-level positioning in kinematic mode given a sufficient convergence period.
