Problems solved by technology

[0004] The traditional emergency satellite launch orbit planning is mainly aimed at the planning and design of the satellite orbit after orbiting, usually without comprehensive consideration of the influence of various factors such as the launch orbit model, orbit return characteristics, illumination conditions constraints of optical loads, and the complex motion model of the earth.

Embodiment Construction

[0154] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0155] The problem to be solved in this satellite orbit planning and design is based on the selected target area information, the constraints of the orbit regression characteristics, the constraints of the reconnaissance load, the launch deployment parameters (including the location of the launch point, the completion time of launch deployment, and the launch orbit data, etc.) parameters) and accurate earth motion models to complete the planning and design of sun-synchronous circular orbits for the detection of different types of target areas.

[0156] According to the satellite launch orbit parameters and operating orbit parameters, a mathematical model is constructed for the problems that need to be solved in the above orbit planning and design.

[0157] Under ideal conditions, the thrust of the satellite during launch and orbit can be approximated as th...

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...
