 The spacecraft telemetry transmitter is most often a VHF transmitter operating at either the 145 or 436 MHz range and providing a low data rate with an omnidirectional or near-omnidirectional on-board antenna. A high data rate is not needed here as the amount of telemetry information from the device is usually much lower than the data rate from the payload for which this satellite was launched into space. Additionally,​ if there are problems on-board and if the device loses its orientation,​ this communication channel will remain available in order to obtain critical information about the state of the on-board service systems and restore the satellite'​s operability. The spacecraft telemetry transmitter is most often a VHF transmitter operating at either the 145 or 436 MHz range and providing a low data rate with an omnidirectional or near-omnidirectional on-board antenna.
