Abstract

The invention provides a satellite autonomous power-on system and a control method thereof. The system comprises: a first-stage separation circuit which is configured to provide a first control signaland a first power supply signal according to a satellite-rocket separation state; a second-stage separation circuit which is configured to provide a second power supply signal according to a first remote control instruction; a satellite-borne computer which is configured to provide a discharge instruction according to the first control signal; a first-stage discharge circuit which is configured to switch on a circuit between a bus and a storage battery according to the first power supply signal and the second power supply signal; and a second-stage discharge circuit configured to turn on thecircuit between the bus and the battery according to the discharge instruction.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a satellite autonomous power-on system and a control method thereof. Background technique [0002] Micro-nano satellites have the characteristics of low cost and short development cycle, and have been more and more researched and applied all over the world. Since the capacity of the battery used is generally very small, and the time from launch to orbit of the satellite is fixed, if the design method of the traditional satellite is adopted—the satellite is in the working state during launch, the discharge depth of the battery may decrease after the satellite is separated from the carrier. Reaching more than 70%, there is a risk of satellite power failure or even loss. Therefore, it is necessary to design a circuit so that the satellite is in a power-off state during the launch phase, and is automatically powered on after being separated from the carrier. [0003] Satellites ...
