Telecommand
Telecommand is a system that allows remote control of a spacecraft or satellite from the ground. It involves the transmission of commands from a ground station to the spacecraft, which then executes the commands. Telecommand is used for a variety of purposes, including spacecraft attitude control, instrument activation, and data acquisition. The telecommand system typically consists of a ground station, a communication link, and an onboard receiver and decoder. The ground station sends commands to the spacecraft via the communication link, and the onboard receiver and decoder process the commands and execute them. Telecommand is an essential component of spacecraft operations, as it allows ground operators to control the spacecraft and perform scientific experiments and observations.
