Non-Precision Approach Availability Sensitivity to GPS Satellite Constellation Configuration

Jya-Syin Wu, Nitin Pandya, Jeff Lewellen, John Angus

Abstract:	The Service Availability of satellite based navigation supporting Non-Precision Approach (NPA) is highly sensitive to the GPS satellite constellation characteristics. This paper explores NPA Service Availability sensitivity for such GPS satellite constellation parameters as quantity of GPS satellites, position of GPS satellites, and policy for reconfiguration following a failure. The basis for this analysis will be the Horizontal Protection Level (HPL) criteria for NPA service in accordance with the Minimum Operational Performance Standards for Global Positioning System/Wide Area Augmentation System Airborne Equipment, RTCA/DO-229A [1].
