1. A method for providing performance control of a transmitted signal, comprising:
- measuring a performance parameter of a received non-communication signal;
measuring a performance parameter of a loopback signal; and
adjusting power of the transmitted signal in response to the performance parameter of the received non-communication signal and in response to the performance parameter of the loopback signal.

Abstract
A method for providing power control to a uplink signal, comprising an uplink station transmitting an uplink signal to a satellite. The satellite also transmits a loopback signal representing the received uplink signal back to the uplink station. The satellite also transmits a beacon signal to the uplink station. The uplink station adjusts the power of the uplink signal based on measurements of the beacon signal and the uplink signal.
