Problems solved by technology

[0005] However, these methods mainly achieve the improvement of orbit determination accuracy through multi-source data fusion processing or the use of multi-satellite systems for multi-station observations, and do not solve the problem of improving the orbit determination accuracy of single-satellite observation data of a single type of payload.

Abstract

The invention discloses a space debris orbit determination traversal observation method and system. A camera installed in a +Y-axis direction of a satellite arranged on a terminator sun synchronous orbit is controlled to rotate around a +Z axis; large-range scanning from a starting deflection angle to an ending deflection angle is achieved, then space debris orbit determination traversal observation of the synchronous belt is achieved; and in the observation process, through real-time calculation, the rotating angle of a satellite around the +X axis of a satellite body is controlled to ensurethat the visual axis of a camera is always perpendicular to the geosynchronous belt at the specified latitude.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a space debris orbit determination and traversal observation method. Background technique [0002] At present, the number of various space vehicles and debris has increased significantly, and space activities have become increasingly frequent, posing a serious threat to satellite safety, especially the geosynchronous belt is the gathering place for many communication, broadcasting, meteorological, early warning and military reconnaissance satellites. Therefore, space debris in the synchronous belt Observation is becoming more and more important. [0003] Space debris observation includes ground-based and space-based methods. Compared with ground-based observation, space-based space debris observation has higher quota coverage and observation timeliness. However, limited by the limitation of sensor capabilities and the constraints of orbital periodicity, the observation arcs o...
