| This system is used to transmit telemetry and telecommand and to pilot the gondola over the Earth surface except over the two Poles. |
| Some experiments also have a video downlink and a telecommand uplink which allows the scientists to control vital experiment parameters in real time from the ground. |
| In the past few years, we have executed a major programme of upgradation of different components of balloon production, telemetry and telecommand hardware and various support facilities. |
| A general set of functional requirements as well as a protocol for communication is defined in the SA ECSS-E-70-41A sTelemetryTelemetry and telecommand packet utilization. |
| Eastern stratospheric seasonal winds transport them over the Mediterranean and the flight termination by telecommand and recovery is accomplished in Spain. |
| The second application is for the provision of telecommand links to a constellation of low earth orbit satellites. |
