Abstract
The invention relates to the command link of a satellite, also referred to as the telemetry, tracking and control link. Depending on the bit rate needed for the link, the invention proposes using either direct modulation of a carrier to transmit at high bit rates or subcarrier modulation of the carrier to transmit at low bit rates. The invention also proposes a receiver and a transmitter for receiving and transmitting on the command link.
