Before any telemetry can be sent to the UCS it must be registered.
Each telemetry field supported by the vehicle should be registered via Register_vehicle.register_flight_controller.telemetry_fields message (See Register_field message).
All telemetry values are considered valid until explicitly reported as N/A by the VSM.
VSM will send N/A automatically depending on timeout upon field creation. This timeout value is used only by VSM-SDK and not communicated to UCS.
VSM can register any set of telemetry fields but there are some built in telemetry field names which are treated specially by UCS.
Registering different semantic for these values will lead to undesired results.
