Wood star detection leveraging flight orbit optimization design method

Abstract

The invention discloses a wood star detection leveraging flight orbit optimization design method, which comprises the following steps of setting a flight sequence as earth-earth-wood star, and establishing an in-plane elliptical earth and wood star analysis ephemeris model; designing a detector and earth resonance emission algorithm, ensuring that the detector is emitted to leave the earth according to a given resonance ratio, establishing a transfer orbit model from deep space maneuver to earth leveraging by utilizing a Lanbert algorithm, setting an earth leveraging flying height, and establishing a transfer orbit model after earth leveraging; defining the earth borrowing moment and the emission moment as phase angle increments, and aiming at an emission window of a certain year, taking the emission moment, the resonance ratio and the phase angle increments as optimization variables to construct a multi-layer nested optimization strategy. Accurate guessing of the initial value of theoptimization variable can be realized, the robustness and rapidity of wood star detection transfer orbit optimization are effectively improved, and a rapid and effective analysis method is provided for rapid analysis and orbit optimization design of a launch window.

Description

technical field [0001] The invention relates to the technical field of deep-space exploration orbits, in particular to a design method for Jupiter exploration orbits by force. Background technique [0002] Jupiter is the planet with the largest natural satellite system in the solar system. So far, 67 satellites have been discovered, of which the 4 most massive are called Galilean satellites. The exploration of Jupiter will help people study the origin and evolution of the solar system, search for the life forms of extraterrestrial celestial bodies, and uncover the mystery of the birth of life. The exploration of Jupiter and its satellites has become the mid- and long-term strategic goal of space powers such as the United States, Japan, and Europe. Historically, people have conducted many explorations of Jupiter, but most of them were limited to flyby detections, such as Pioneer 10 and 11, Voyager 1 and 2, Cassini-Huygens and New Horizons. The mission, the degree of detecti...
