Open Architecture In a DOD Receiver: Results and Prospect

R.G. Bartholomew

Abstract:	This paper describes the sofhvare architecture of the DOD Standard Miniaturized Airborne GPS Receiver (MAGR), designed and produced by Collins Avionics 8~ Communications Division, Rockwell International, in terms of the Open Systems Environment defined by the Application Portability Profile of the National Institute of Standards and Technology. OSE concepts are presented; so also is the MAGR’s software architecture. Details of the chamrel management function’s architecture are presented, along with changes that allowed for expansion from a five chattel receiver, to a 10 channel, 18 channel, and fmally a 24 channel receiver. Problems remaining, that complicated the upgrade, are described along with potential solutions. Data approximating the effort involved in each of these expansions is presented supporting the contention that an OSE software architecture expedites the inclusion of advanced capabilities into DOD standard GPS user equipment. A potential propagation of this concept, that could expedite the inclusion of advanced avionics capabilities onto DOD avionics platforms, is described.
