摘要：
A system is provided for enhancing coverage for a mobile satellite service, the system comprising a signal threshold comparator module for monitoring a predetermined threshold for a satellite service signal received on a first frequency band, a signal gain block operable to vary amplification of the satellite service signal received on a second frequency band in response to the threshold, and a satellite receiver for decoding the satellite service signal received on the first and second frequency bands.
