Embodiment Construction
[0048]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] The invention provides a method for detecting the horizontal deviation of the antenna phase center, such as figure 1 mentioned, including:
[0050] Step 101, obtaining D sets of observation data between the reference antenna and the antenna under test, each set of observation data is obtained by observing the antenna under test after being rotated and placed at an angle X; X=360 / D, D is greater than or equal to 3;
[0051] Step 102,...

The invention provides a method and device for detecting an antenna phase center horizontal deviation, and relates to the technical field of navigation. The method includes the steps that D groups ofobservation data between a reference antenna and an antenna to be detected are acquired, and each group of the observation data is obtained by observation after the antenna to be detected rotates by Xdegrees and is placed; X=360 / D, and D is greater than or equal to 3; for each group of the observation data, baseline data, corresponding to each group of the observation data, of the reference antenna and the antenna to be detected are determined; the geometrical relationship constructed between the baseline data, a phase center of the reference antenna, a geometric center of the antenna to be detected and a phase center of the antenna to be detected is determined; and a deviation value between the phase center of the antenna to be detected and the geometric center of the antenna to be detected is determined according to the geometrical relationship corresponding to the D groups of observation data. Compared with the prior art, specific measurement equipment is not required, the antennato be detected and the reference antenna do not need to be initially oriented, and the deviation value between the phase center and the geometric center of the antenna to be detected can be determinedmore simply and accurately.
Description
technical field [0001] The invention relates to the technical field of navigation, in particular to a method and a device for detecting horizontal deviation of an antenna phase center. Background technique [0002] The full name of GNSS is Global Navigation Satellite System (Global Navigation Satellite System), which refers to all satellite navigation systems, including global, regional and enhanced, such as GPS in the United States, Glonass in Russia, Galileo in Europe, China's Beidou satellite navigation system, and related augmentation systems, such as WAAS (Wide Area Augmentation System) in the United States, EGNOS (European Geostationary Navigation Overlay System) in Europe, and MSAS (Multifunctional Transport Satellite Augmentation System) in Japan, etc., also cover the and other satellite navigation systems to be built in the future. [0003] The antenna phase center refers to the electrical center of the antenna, and the observations obtained through high-precision ...
