Method for limiting interference between satellite communications systems
First Claim
1. A method to reduce interference between a GSO satellite and its GSO ground station when operating an NGSO satellite or constellation of satellites orbiting at medium earth orbit (MEO), comprising the step of:
- terminating all transmission signals generated on a particular NGSO satellite or emanating from an NGSO ground station in communication with the NGSO satellite when the NGSO satellite is in an exclusion zone defined for a GSO ground station antenna.

Abstract
Boeing achieves satellite diversity by having a large discrimination angle for a MEO constellation of communications satellites to limit interference in the Ku-band with GSO communications systems. Each satellite entering an exclusion zone over a GSO ground station terminates all transmissions to provide EPFD within acceptable limits. The Boeing MEO constellation preferably comprises 20 satellites, 5 in each orbit. The four orbits are inclined at about 57° with respect to the equator. Services include an Integrated Digital Service (IDS) and Backhaul Data Service (BDS) to accommodate the needs of different users.
