Wide-Area Differential Global Positioning System (WDGPS)/Wide-Area Integrity Broadcast (WIB) Alternatives Analysis

Abstract

A study was conducted by MITRE to determine alternative concepts for Wide-area Differential Global Positioning System (WDGPS) for the national airspace system (NAS). The study was undertaken in support of the concept exploration phase analyses required by the Transportation System Acquisition Review Council (TSARC). The results of the study are documented in this paper. The paper provides a description of alternatives to WDGPS, various alternative implementations of WDGPS, advantages and disadvantages of each alternative, and risk areas which were identified. Two WDGPS architecture end-states are recommended. The preferred end-state will depend on the results of required trade-off studies which are identified in this paper. A plan for the transition from the Wide-area Integrity Broadcast (WIB) to the selected WDGPS end-state architecture is also presented. GPS, Global positioning system, DGPS, TSARC, Integrity.
