Abstract: This paper documents a system description and operational concept for ensuring the integrity of the Global Positioning System (GPS) signals-in-space for use in the National Airspace System. The concept employs a ground monitoring network, L-band transponders placed onboard already planned geostationary communication satellites to broadcast integrity data, and an integrated receiver containing both the GPS and the GPS Integrity Channel (GIG). The three, aforementioned system segments are described. The feasibility of employing a network of only four ground monitors to cover CONUS is analyzed. A discussion concerning implementation of such a system is also presented.
