- Abstract
- Provided are an apparatus and method for executing a telecommand on a geostationary satellite, and an apparatus and method for verifying a telecommand execution status on a geostationary satellite ground control system. When a telecommand on a satellite is executed, the satellite generates command execution verification words for the executed telecommand and adds the generated command execution verification words to a telemetry transfer frame, and thus a satellite ground control system can easily verify the telecommand execution. In addition, when telecommand execution result is verified by a satellite ground control system, since an execution result of a time-tag telecommand can be verified without a time delay through command execution verification words provided by a satellite, and a telecommand image DB, a telecommand verifier DB, and a telecommand verifier provided by the satellite ground control system, a series of processes from transmission to verification of a telecommand, in particular a time-tag telecommand, can be automatically processed in real-time without intervention of an operator.
