Embodiment

[0025] Take the uniform transfer of the orbital plane launched by a three-star rocket as an example.

[0026] (1) Orbital inclination i=25°, orbital height H f =700km, the deployment time of the constellation is required to be no more than half a year, and the total fuel consumption shall not exceed 30kg.

[0027] (2) According to the uniform distribution requirements of the given orbital planes, the drift rates of the orbital planes of the two stars are respectively and Marked by numbers 01 and 02, the orbital height of the drift relative to the reference star 03 is H f . According to the formulas (1) and (2), it can be known that the altitudes of the stars 01 and 02 are relative to H f The maximum difference is -212km and 212km respectively, that is, the highest altitude of 01 star is 488km, and the lowest altitude of 02 star is 912km.

[0028] (3) Assuming that the weight of the whole star is 500kg, and the rated vacuum ratio of the engine is 200s, it can be calculat...

Abstract

The invention discloses a method for distributing and transferring multiple satellites launched by one rocket to different orbit planes. Firstly, orbit injection dip angles i, target heights Hf, time T for completing deployment of tasks and orbit plane drifting distances delta omega needed by all the satellites need to be determined, and critical height differences delta a for transferring the satellites to the target obit planes in the assigned time T are calculated according to the input conditions. Satellite drifting starting heights are provided through a piggybacking separation mode or an upper-level orbital transferring mode, or when the quantity of fuel carried by the satellites enables corresponding orbit transferring capability to be achieved, drifting is begun by directly transferring to the drifting starting heights from the orbit injection height. The different drifting starting heights corresponding to all the satellite are set under the premise that the satellites can arrive in the assigned time T, and the satellites are restored to designed heights respectively after arriving at the target orbit planes. Selection of obits and piggybacking is carried out on piggybacking satellites or multiple constellation satellites according to given drifting time in tasks and existing orbit injection conditions, different fuel demands of all the satellites are deployed when piggybacking conditions exist or constellation tasks meet requirements, and different orbit distributing and transferring are completed after obit injection according to designed drifting modes.

Description

technical field [0001] The invention relates to a method for distribution and transfer of multiple satellites in different orbits with one arrow, and belongs to the technical field of satellite development and deployment. Background technique [0002] The launch of multiple satellites with one arrow can save the cost of satellites entering orbit, especially for satellites with small mass and volume. Independent satellites can average the launch cost, and functionally related satellites can form a constellation that cannot be compared with a single satellite. system performance. [0003] For launch missions with the same orbital height, inclination and eccentricity, the launch cost can basically be calculated on a per-time basis. When the carrier type spectrum corresponds to the maximum orbital load weight of a certain rocket has been designed and determined, it will not be due to the reduction in the payload weight. And reduce launch costs. Multiple satellites with one arr...
