Problems solved by technology

[0019] Obviously, although the derivation process of the existing star-seeking control parameters is simple, there are (incorrect or imprecise) problems in the theoretical basis. The star-seeking method at the ground point does not match the actual situation. not big

Abstract

The invention relates to the technical field of a geostationary satellite of a stationary orbit, and particularly discloses a digital finder method employing a geostationary satellite of a stationary orbit. The digital finder method comprises the following steps: directly collecting position information of a ground point through a global position system (GPS) or Beidou terminal equipment; inputting parameters of position information of the ground point through a call instruction based on a http protocol; calculating through a position processing module of the appointed ground point, an ellipsoid secondary variable calculation module, a sighting distance processing module from the appointed ground point to the appointed satellite, an elevation processing module from the appointed ground point to the appointed satellite, and a true north azimuth processing module from the appointed ground point to the appointed satellite; solving the results of a sighting distance L from any ground point to the satellite, the elevation beta from any ground point to the satellite and an azimuth angle alpha from any ground point to the satellite; carrying out conversion through a data conversion module, displaying the finder result in a human-computer interaction interface, and determining the relative positions of the ground point and the satellite through the finder result. The digital finder method is rigorous in theory, efficient, and high in calculating result accuracy.

Description

technical field [0001] The invention relates to the technical field of geostationary geostationary satellites, in particular to a method for realizing digital star-seeking through geostationary geostationary satellites in field geological surveys. Background technique [0002] The space segment of the "Beidou" satellite navigation system consists of 5 geostationary orbits and 30 non-stationary orbit satellites, among which 5 geostationary satellites ( figure 1 Beidou-G4, G1, G3, G6, G5) have three major functions of short message communication, general positioning and timing service, and its short message communication can transmit up to 77 effective bytes per frequency, and the horizontal positioning accuracy Usually about 100m, the satellite is about 35766922m above the ground. The positioning and communication technology of Beidou satellite is in the stage of popularization and application in the Asia-Pacific region. Its short message communication function can provide s...
