摘要
A satellite command system and method that provides satellite commanding using remotely-controlled modulation of telemetry parameters on-board a satellite. Software is provided on each of the redundant processor units that creates separate DMA command input pathways to the redundant processor units. A command translator is used at a ground station to translate a command that is to be implemented on the satellite into a form ready for modulation. The command information is uplinked to the satellite by remotely manipulating (modulating) a quantity that can be measured by the on-board computer using its telemetry collection functions. The software implemented in processor units recognizes the modulation and processes it to reconstruct the command. The reconstructed command is passed to the processor unit, which then executes the command.
