Abstract

The invention discloses an orbit planning method of a sun-synchronous circular orbit. A satellite launching orbit model, orbit regression characteristic constraints, target area illumination condition constraints and an accurate earth motion model (earth complex motion models such as age difference, nutation, rotation and polar movement are considered in the design) can be combined to design a sun-synchronous circular orbit scheme so as to realize rapid and effective detection of a target area. The problem to be solved by the satellite orbit planning design is to complete the planning design of a sun-synchronous circular orbit for different types of target area detection according to selected target area information, constraint conditions of orbit regression characteristics, constraint conditions of reconnaissance loads, launch deployment parameters, an accurate earth motion model and other data.

Description

technical field

[0001] The invention relates to the technical field of orbit planning, in particular to an orbit planning method for a sun-synchronous circular orbit. Background technique

[0002] The difference between conventional earth observation satellite orbit planning and emergency satellite launch orbit planning lies in the different mission design concepts. The conventional earth observation mission first launches the earth observation satellite, and after the specific observation target is given, the satellite is sent into the observation orbit through orbital maneuvering to observe the target. Satellite orbit planning for emergency satellite launch missions is driven by the needs of space missions. Satellite orbit planning is usually carried out according to the requirements of reconnaissance target missions, and the parameters of satellite launch orbits and operating orbits are weighed so that they can be quickly launched under the premise of meeting emergency la...
