Design method and system for impact detection track based on loading form

Abstract

The invention belongs to the field of space detection, particularly relates to an impact detection track design method and system based on a carrying form, and aims to solve the problem that in the prior art, an observer track and an impactor track cannot be cooperatively designed according to impact detection task requirements of a detector in a form that an observer carries an impactor. The present invention comprises: a main body; establishing a reference frame, constructing a two-body model, an accurate dynamic model and an engineering constraint model based on the reference system; and calculating an initial orbit set error constraint condition of the impactor through the constructed model, screening out a nominal orbit of the impactor, calculating an orbit transfer moment and an orbit transfer speed of the observer based on the nominal orbit, and calculating an accurate nominal orbit of the observer based on an accurate power model through a targeting method. According to the invention, the cooperative design of the observer and the impactor track is realized, and a reference is provided for a small celestial body impact detection task.

Description

technical field [0001] The invention belongs to the field of space detection, and in particular relates to a design method and system for an impact detection track based on a carrying form. Background technique [0002] In the field of deep space exploration, impact detection is a new form of detection of extraterrestrial celestial bodies. Impact detection uses high-speed moving impact detectors to directly hit the predetermined surface of the target celestial body, penetrate into the surface of the object, and directly contact it. A probe that measures internal structure and composition. Compared with traditional landing, fly-by or fly-around detection, impact detection can obtain higher scientific output at a lower cost, and it is a detection form with great engineering application potential. In addition, for small celestial bodies such as asteroids, the impact can realize their orbital deflection, which is a potential application method to eliminate asteroids that threat...

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, the orbit design method of the prior art only designs the orbit or landing orbit of the detector to the target celestial body, which cannot meet the impact detection task requirements of the detector in the form of an impactor carried by the observer. For the problem of collaborative design of the observer track and the impactor track, the present invention provides a method for designing an impact detection track based on a carrying form, the method comprising:
