The invention provides a method and device for detecting the horizontal deviation of the antenna phase center, which relates to the field of navigation technology. The method includes: obtaining D groups of observation data between the reference antenna and the antenna to be tested, and each group of observation data is the rotation X angle of the antenna to be tested Obtained by observation after placement; X=360 / D, D is greater than or equal to 3; for each set of observation data, determine the baseline data of the reference antenna corresponding to the observation data and the antenna to be tested; determine the baseline data and the phase center of the reference antenna 1. The geometric relationship constructed by the geometric center of the antenna to be tested and the phase center of the antenna to be tested; according to the geometric relationship corresponding to the observation data of group D, determine the deviation value between the phase center of the antenna to be tested and the geometric center of the antenna to be tested. Compared with the prior art, no specific measuring equipment is required, and the initial orientation of the antenna under test and the reference antenna is not required, and the deviation value between the phase center and the geometric center of the antenna under test can be determined more simply and accurately.
Description
Technical field[0001]The present invention relates to the field of navigation technology, and more particularly to detecting methods and apparatus for detecting an antenna phase center level deviation.Background technique[0002]GNSS's full name is Global Navigation Satellite System, which is a global, regional and enhanced, regional Glonass, Glonass, Glonass, Russia, China's Glonass, China Beidou satellite navigation system, as well as related enhancements, such as WaaS (wide-area enhancement systems), European EGNOS (European static navigation overlap system) and Japan's MSAS (multi-functional transport satellite enhancement system), etc. Other satellite navigation systems to be built after the construction will be built.[0003]The antenna phase center refers to the electrical center of the antenna, and the observations obtained by satellite navigation high-precision measurements are based on the antenna phase center. In positioning measurements, due to a variety of reasons, there is...
