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 distance-measuring device and its usage method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] Such as Figure 1-Figure 4 As shown, among the systematic errors of the double-star rendezvous measurement of the present invention, the independent systematic error of a single star becomes a random error during the rendezvous measurement process, and it can be approximately considered that the two-star rendezvous errors are not related, and at this time the systematic error is reduced to 0.7 times of the original . This patent adopts double star rendezvous to measure the angle, and proposes a high-precision angle distance information detection device and its use method, which improves the angle measurement accuracy and facilitates high-precision orbit det...

Abstract

The invention discloses a space-based double-satellite rendezvous angle and distance measuring device and a use method thereof, and belongs to the technical field of optical measurement. Two space-based double-satellite rendezvous angle and distance measuring devices at different positions and two satellites are included. Each space-based double-satellite rendezvous angle and distance measuring device comprises a large-aperture optical detection system and an information processing and transmission system electrically connected with the large-aperture optical detection system. Each satellite comprises a precise tracking unit, a servo control system, a communication system, a GPS positioning system and a master control system, wherein the GPS positioning system is electrically connected with the communication system, the communication system is electrically connected with the corresponding information processing and transmission system, the servo control system is electrically connected with the precise tracking unit, the precise tracking unit is electrically connected with the corresponding large-aperture optical detection system, the servo control system is electrically connected with the corresponding information processing and transmitting system, and the master control system is electrically connected with the corresponding space-based double-satellite rendezvous angle and distance measuring device and the corresponding satellite. According to the invention, the angle measurement precision can be improved, and more accurate data can be provided for high-precision orbit determination.

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-measurement and distance-measurement device and its application method. Background technique [0002] The space-based observation system for space targets 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 means, space-based space target surveillance currently mainly uses 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 relatively large defects in the detection distance. The spac...
