Abstract
A hybrid satellite communication system in which a hub station transmits signals to remote stations through a satellite at a relatively low frequency which is unaffected by weather effects and in which the remote stations transmit signals to the hub station at a relatively higher frequency which enables the use of more economical equipment at the remote stations. The hub station senses the signal quality or strength received from each remote station and transmits power control signals to remote stations with poor signal strengths to cause such remote stations to increase their output power to overcome weather effects. The power control signals are transmitted on the lower frequency to prevent the power control signals from being masked by the weather effects.
