Mobile Satellite Ventures was awarded its fifth hybrid satellite/terrestrial system patent, which covers 34 claims. The award of this patent brings the total number of award claims for MSV-originated ancillary terrestrial component (ATC) patents to about 650.

The most recent patent, Systems and Methods for Handover Between Space-based and Terrestrial Radiotermial Communications, and for Monitoring Terrestrially Reused Satellite Frequencies at a Radioterminal to Reduce Potential Interference, describes ways of minimizing uplink interference from ATC terminals to a satellite. The patent also describes how satellite signals received at ATC terminals may be monitored to determine potential interference.
