Embodiment

[0024] Taking the moon interference protection operation during a normal operation as an example, the implementation method of using the present invention to realize the protection of one infrared earth sensor probe at a specified time is described.

[0025] According to the estimated results of moon interference protection, relative to T 0 From time 202965180 seconds to 202965840 seconds, the moon will interfere with infrared earth sensor probe 1 (there are 4 infrared earth sensor probes). Therefore, the infrared earth sensor probe 1 needs to be prohibited during this period, and the operation of restoring all infrared earth sensor probes is performed before the prohibition, and all infrared earth sensor probes are restored after the interference is over.

[0026] (1) This task is to restore and prohibit the infrared earth sensor probe 1. According to the task, the format of the instruction content is determined as the control instruction of the infrared earth sensor in the o...

Abstract

The invention relates to a delay execution method of proportional type remote control instructions of a high orbit satellite. When remote control instructions of a high orbit satellite cannot be injected due to the reasons like a satellite is not in a measurement and control area and is abnormal in gesture and a measurement and control channel is abnormal and the like, and the risk that ground cannot control the orbital satellite control subsystem exists. According to the situation and based on the mechanism of proportional type remote control instructions, absolute star timing is imported into the proportional type remote control instructions, instruction formats are designed, and the purpose of executing proportional type remote control instructions at a specified time is achieved. Ground remote control operations under the situation that a satellite cannot be measured and controlled are achieved through the delay execution method of the proportional type remote control instructions of the high orbit satellite, and reliability and safety of the satellite are achieved. The delay execution method of the proportional type remote control instructions of the high orbit satellite has no extra requirements of a remote control mechanism and hardware, and is convenient to achieve, very feasible, and capable of being popularized to any satellites adopting the proportional type remote control instructions.

Description

technical field [0001] The invention relates to a delayed execution method of a proportional remote control command for medium and high-orbit satellites, which is suitable for satellites using a software processing proportional remote control command mechanism. Background technique [0002] On navigation satellites, the control computer application software is responsible for receiving proportional remote commands. Each proportional remote control command is composed of 20-bit binary code, among which the upper 4 bits are the address, and the 4-bit address can be decoded to distinguish 16 different proportional remote control command channels. The lower 16 bits are the content of the command. One remote control injection operation can send more than one remote control command, and each remote control command consists of more than one command content. Channel 15 (that is, the address is 0x1111) is used as the proportional remote control command channel for immediate executio...
