Problems solved by technology

When the satellite locates the target through the attitude of the satellite, due to the interference of thermal deformation and other interference in the space environment during the orbital movement of the satellite, the original satellite attitude determination method cannot meet the accuracy requirements
In addition, because the satellite attitude determination system may have deviations and failures, it will also lead to a decrease in the accuracy of attitude determination, which in turn affects the accuracy of satellite positioning

Embodiment Construction

[0053] The attitude of the satellite refers to the attitude of the satellite body relative to the reference object on which the satellite operates. The positioning of the target point by the satellite needs to be obtained from the attitude of the satellite and the relative position between the satellite and the target point. Therefore, accurately obtaining the attitude information of the satellite is the key to the accurate positioning of the satellite.

[0054] In the embodiment of the present invention, the position information of the reference point is acquired through the imaging payload carried by the satellite, and relatively accurate attitude information can be obtained, which can be used to determine the attitude deviation of the satellite. Then, the satellite attitude information obtained through the satellite attitude system is compensated by the obtained attitude deviation, and the target point can be accurately located by using the compensated satellite attitude inf...

Abstract

The invention discloses a fast target positioning method based on ground object coordinate information, which determines the attitude deviation of the satellite according to the position information of the reference point and the orbit information of the satellite; and determines the attitude information of the satellite based on the attitude deviation Perform deviation compensation; determine the position information of the target point according to the compensated attitude information. The invention also discloses a device for quickly locating a target based on ground object coordinate information, a satellite carrying device and a storage medium.

Description

technical field [0001] The invention relates to satellite imaging positioning technology in the field of satellite positioning, in particular to a method, device, satellite carrying equipment and storage medium for fast target positioning based on ground object coordinate information. Background technique [0002] With the development of aerospace technology, the positioning of ground targets can be realized through satellites. Followed by the requirements for satellite positioning accuracy. When a satellite locates a target through the attitude of the satellite, due to the interference of thermal deformation and other interferences in the space environment during the orbital movement of the satellite, the original satellite attitude determination method cannot meet the accuracy requirements. In addition, because the satellite attitude determination system may have deviations and failures, it will also lead to a decrease in the accuracy of attitude determination, which in t...
