Problems solved by technology
In the traditional positioning method, only one satellite is often used to measure the azimuth of the target. At this time, the angle measurement error of the satellite has a great influence on the azimuth measurement of the target.
[0008] At present, my country's ground-based and space-based detection systems have developed rapidly, but there is still a problem that the low accuracy of angle measurement restricts the accuracy of orbit determination

Embodiment Construction
[0040] In order to better understand the purpose, structure and function of the present invention, a space-based double star rendezvous angle measuring and ranging device of the present invention and its using method will be described in further detail below with reference to the accompanying drawings.
[0041] like Figure 1-Figure 4 As shown, among the systematic errors of the double-star intersection measurement of the present invention, the independent systematic error of a single star becomes a random error during the intersection measurement process, and it can be approximated that the errors of the two stars are not related. At this time, the systematic error is reduced to 0.7 times of the original. . This patent adopts the angle measurement of double star rendezvous, and proposes a high-precision angular distance information detection device and its use method, which improves the angle measurement accuracy and facilitates high-precision orbit determination. The focus ...

Description
technical field [0001] The invention belongs to the technical field of optical measurement, and in particular relates to a space-based double star rendezvous angle measuring and ranging device and a method for using the same. Background technique [0002] Space target space-based observation system is an important development direction of space situational awareness in the future. It has become a cutting-edge technology in the field of space exploration today, and has strategic significance for space missions and even national security. [0003] In terms of target detection methods, space-based space target monitoring mainly adopts two major technologies, optical and microwave. Among them, microwave radar is an active space target detection method. Due to the limitations of satellite power, antenna technology, scanning technology and on-board signal processing technology, there are still major defects in detection distance. The space-based optical monitoring system occupies...
