Abstract

The invention relates to a satellite passive orbit measurement method and system, and relates to satellite technology. The satellite passive orbit measurement method of the present invention is to passively receive the radio signal broadcast by the satellite through the ground station, so as to realize the position measurement and orbit measurement of space objects such as satellites. The specific method is to set up 2 to 4 antennas in each measurement station, and use carrier signal waveform correlation to obtain the range difference D between the two antennas when receiving satellite signals. The rendezvous measurement model obtains the position and orbit of the satellite in space. While completing the above-mentioned rough orbit determination, 10-100 satellite position accuracy monitoring reference stations shall be established within the coverage area of ​​satellite signals. The vector correction number of the satellite position is obtained, so as to achieve the second high-precision orbit determination of the satellite.

Description

Satellite passive orbit measurement method and system technical field

[0001] The present invention relates to the technical field of satellites, and is a satellite passive orbit measurement method and system. Background technique Along with the rapid development of space technology, the aircraft of space motion is more and more. Orbital measurement of aircraft Needs have grown dramatically, especially with the establishment of the United States Global Positioning System, which uses navigation satellites as an interstellar position reference and The atomic clock is used as the time reference, so that high-precision positioning can be easily realized all over the world, and the application value is great. In order to protect To ensure the accuracy of navigation and positioning, it is necessary to accurately describe the spatial position of navigation satellites, that is, to achieve high precision of navigation satellites. Orbit determination. The classic method is to ...
