Abstract

The invention relates to a method and a device for judging satellite visibility under carrier rotating condition. The method mainly includes: building a carrier coordinate system, calculating carrier rotating angles, and calculating satellite positions in the carrier coordinate system according to the carrier rotating angles; and calculating satellite elevation angles according to the satellite positions in the carrier coordinate system, comparing the satellite elevation angles and satellite screening angles, and judging satellite visibility according to comparison results. In an embodiment of the method and the device, the carrier coordinate system is built, positions of satellites in a horizontal coordinate system are shifted into the carrier coordinate system and the satellite elevation angles are calculated, and accordingly the satellite visibility can be effectively judged according to the satellite elevation angles under carrier rotating condition.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method and device for judging satellite visibility under the condition of carrier rotation. Background technique

[0002] Following the GPS (Global Positioning System, Global Positioning System), countries are committed to developing their own satellite navigation systems. On the basis of the Beidou first-generation satellite navigation system, my country has created a new situation for the Beidou-2 satellite navigation system and achieved a stage. sexual outcomes. However, the development of Beidou satellite navigation system is facing many challenges. In order to carry out the research on Beidou guidance technology, the equipment of the rotating system also performs high-speed rotating motion while flying at high speed, resulting in rapid changes in the number of visible stars, the amplitude of the received satellite navigation signal, Doppler, and carrier phase of the...
