[0005] The existing double-star formation method is designed for traditional satellites. Since the structure and size of micro-nano satellites and traditional satellites are different, when the micro-nano-satellite double-star short-distance formation adopts the existing double-star formation method, it will consume a lot of fuel energy and ground satellite monitoring. resources, and due to limited satellite monitoring resources, micro-nano-satellite formation missions cannot be fully guaranteed

Abstract
The invention discloses a double-satellite close range formation method for a micro-nano satellite, and is used for realizing the close range formation of two micro-nano satellites. The method comprises the following steps that: establishing a double-satellite formation coordinate system, establishing a relative motion equation, carrying out double-satellite formation configuration initialization,carrying out double-satellite inter-satellite communication, and maintaining the double-satellite formation configuration. By use of the double-satellite close range formation method for the micro-nano satellite, the same carrier rocket is used for simultaneously carrying two micro-nano satellites, the launching separation way of the micro-nano satellites and the carrier rocket, the maintaining way of a double-satellite trajectory and an inter-double-satellite communication way are designed, so that micro-nano satellite formation speed can be improved, frequencies for the micro-nano satelliteto carry out active trajectory maneuvering can be effectively reduced, fuel is saved, and in addition, the maneuvering safety of the micro-nano satellite trajectory can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of spacecraft control, in particular to a double-star short-distance formation method for micro-nano satellites. Background technique [0002] According to the current satellite classification method, micro-nano satellites are represented as satellites with a mass of less than 100kg. Compared with traditional satellites, micro-nano satellites have the characteristics of small size, light weight, low cost and short development cycle. However, due to size and energy constraints, compared with traditional satellites, a single micro-nano-satellite has a single function. Currently, a single micro-nano-satellite cannot completely replace traditional satellites. Therefore, two micro-nano-satellites are usually used in a close-range formation, and two micro-nano-satellites are used for double-star coordination to expand the functions of micro-nano-satellites and replace traditional satellites with micro-nano-satelli...
