Abstract: An embodiment disclosed a system for collaborative positioning calibration, comprising at least one reference station and at least one client. The reference station uses a known position and a satellite signal transmitted by at least one satellite to compute a pseudo-range difference of the reference station position and the satellite position, and then broadcasts an area calibration data including at least one pseudo-range difference to at least one client. Based on the area calibration data, the client computes at least one pseudo-range calibration data and outputs a calibrated position of global positioning system.
