Problems solved by technology

The problem with the existing autonomous rendezvous methods is that the control method based on pulse thrust mostly adopts the open-loop control method, and the orbit maneuver is performed by presetting on the ground in advance. The orbit data usually comes from absolute navigation, which is easily affected by orbit perturbation. and rarely consider the cost of equipment during the maneuver

Abstract

The invention discloses a micro-nano satellite in-orbit autonomous rendezvous control method and computer equipment. The method comprises the following steps: calculating relative navigation data and absolute navigation data according to a relative kinetic model and an absolute kinetic model, and calculating a relative average orbit element according to the relative navigation data and the absolute navigation data; performing orbit recursion in a preset time period according to the relative navigation data, the absolute navigation data and the relative average orbit number to obtain orbit recursion data, and judging whether a preset rendezvous condition is met or not according to the orbit recursion data; and if so, calculating two control pulses of a tracking spacecraft at an initial moment and an end point moment, and adjusting the relative orbit parameters of the tracking spacecraft and a target spacecraft according to an orbit control instruction set and the two control pulses so as to allow the tracking spacecraft and the target spacecraft to realize autonomous rendezvous. According to invention, the technical problem that spacecraft orbital transfer rendezvous and docking control precision is low in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of spacecraft orbit control simulation, in particular to a method and computer equipment for on-orbit autonomous rendezvous control of micro-nano satellites. Background technique [0002] Spacecraft rendezvous and docking is a space strategic technology developed along with the trend of the first batch of space technology in the 1960s. As the core component technology of space civil and military strategic applications, it is the successful transition from theoretical research to manned spaceflight. An important symbol for practical engineering applications. Spacecraft rendezvous and docking technology not only represents the development level of a country's aerospace technology, but also a comprehensive display of a country's aerospace technology strength. With the continuous progress and development of aerospace science and technology in contemporary society, spacecraft rendezvous and docking tec...
