In-orbit fuel consumption balancing method of formation satellite system

Abstract

The invention relates to an in-orbit fuel consumption balancing method of a formation satellite system. The method comprises the following steps that 1) after kth formation control, the fuel consumption Ek of the formation control is calculated; 2) after the kth formation control, a formation control parameter [delta]lk of two satellite orbit periods is determined; 3) the sum SEk of cumulative fuel consumption of formation control and a residual error [delta]lk of present formation control are substituted into a formula SEk>=k1&&[delta]lk>=k2 for determination; and 4) if the formula is valid, marks of main and auxiliary satellites are switched autonomous on the satellites, main and auxiliary satellite switching control is carried out via a ground annotation instruction or on satellites autonomously so that a new main satellite operates in a reference orbit, parameters are set as initial values, a new auxiliary satellite executes a formation control task, and the steps 1) to 3) are repeated; or if the formula is invalid, the original auxiliary satellite continues to carry out formation control. The method is high in engineering realization performance, can be used to save fuels, requirements of formation satellite tasks are taken into consideration, and the autonomous level of the satellites can be improved.

Description

technical field [0001] The invention relates to an on-orbit realization method of fuel balance in a formation satellite system. Background technique [0002] With the continuous development of satellite technology, more and more countries and organizations are more and more inclined to use multiple satellites to form a formation satellite system to achieve space mission goals. Therefore, the control task of the formation satellite system is becoming more and more complex, and it is also facing the pressure of high control accuracy, autonomy and long life. [0003] At present, the decisive factors affecting the life of satellites mainly include fuel and electric energy, and fuel consumption is irreversible. Therefore, since the relative relationship between formation satellites needs to be realized through formation control and fuel consumption, the smooth development of formation missions, service life, and control capabilities not only depend on the absolute formation cont...
