GPS position difference principle

  This is the simplest differential method, and any GPS receiver can be modified and composed of this differential system.

  After observing four satellites, the GPS receiver installed on the reference station can conduct three-dimensional positioning and calculate the coordinates of the reference station. Due to the existence of orbit error, clock error, SA effect, atmospheric effect, multipath effect and other errors, the calculated coordinates are not the same as the known coordinates of the reference station, and there are errors. The reference station uses the data link to send out the correction number, which is received by the user station, and the user station coordinates solved by it are corrected.

  Finally, the corrected user coordinates have eliminated the common errors of the reference station and the user station, such as satellite orbit error, SA influence, atmospheric influence, and so on, which improves the positioning accuracy. The above prerequisite is the observation of the same set of satellites by the reference station and the user station. The position difference method is applicable to the case that the distance between the user and the reference station is within 100km.
