Abstract

The invention discloses a method for controlling a rapid autonomous transfer orbit, which includes: judging whether the start time of pulse control has been reached when onboard; performing pulse control, wherein the pulse control works according to a preset pulse mode, and each pulse starts T 1 Duration, off T 2 duration; fine-tuning controls; and end controls. During the entire control process, the transfer time is greatly reduced, and the ground station only needs to receive on-board data for monitoring after entry, reducing the dependence on the ground station and the workload of ground personnel, and greatly improving work efficiency.

Description

technical field [0001] The invention relates to the field of spaceflight technology, in particular to a control method for rapid and autonomous orbital transfer on a star. Background technique [0002] At present, there are two ways to launch satellites. One is exclusive launch, the so-called "chartered car" method, that is, buying a rocket to complete the launch; the other is piggyback launch, which is similar to "ride a car" and only occupies part of the rocket's carrying capacity. With the development of space technology, carrying many small satellites has become a cheap and high-quality "travel" method: for example, in October 2018, when the Sino-French Ocean Satellite was launched, it carried 7 small satellites. Although the carrying method can greatly reduce the launch cost, sometimes it also brings that the carrying orbit is not necessarily the expected target orbital height. For example, in August 2016, the scientific thin atmosphere test satellite carried quantum sa...
