We describe a ectiveness of using formal methods in Space Shuttle software requirements analysis. Several Change Requests (CRs) were selected as promising targets to demonstrate the utility of formal methods in this demanding application domain. A CR to add new navigation capabilities to the Shuttle, based on Global Positioning System (GPS) technology, is the focus of this industrial usage report. Portions of the GPS CR were modeled using the language of SRI's Prototype Verication System (PVS). During a limited analysis conducted on the formal specications, numerous requirements issues were discovered. We present a summary of these encouraging results and conclusions we have drawn from the pilot project.
