In high-precision relative positioning applications of global navigation satellite systems, multipath and phase centre offset/variation remain as the major coupled error sources, as they cannot be eliminated by the differential operation. A circular rotating low-cost antenna is introduced for the rover station in a constrained environment. The spatial diversity of multipath is explored by circular motion to aid the carrier-phase ambiguity resolution and error elimination. The multipath and phase centre offset are separated and estimated. Field tests demonstrate that the proposed method with low-cost antenna is able to achieve the survey-grade precision.
