Abstract: A standalone GNSS receiver saves at each epoch a position and observables based on one or more signals. A reference position associated with a reference epoch is saved with reference observables. At a later epoch, the current position is determined by reference to the reference position and the reference epoch by performing a real time kinematic process. When cycle slip and/or signal lock has occurred, an ambiguity resolution is performed in real time kinematic. A standalone GNSS receiver with ambiguity resolution and real time kinematic at a current epoch achieves centimeter-level position accuracy by fixing ambiguities to integer and performing real time kinematic upon signal restoration. The saved reference data and coordinate serve as a reference station until signal restoration.
