(U) The civil
requirements shown in this appendix were collected during the Position,
Velocity, and Time (PVT) Determination Capstone Requirements Document (CRD) and
Global Positioning System (GPS) Operational Requirements Document (ORD)
development effort. The CRD requirements were developed for a PNT systems
approach. These requirements were not
identified to be satisfied by any particular system such as the Global
Positioning System (GPS), Wide Area Augmentation Systems (WAAS), Local AAS
(LAAS), National Differential GPS (NDGPS), Joint Precision Approach and Landing
System (JPALS), etc.) The requirements listed in this appendix were validated
by the IGEB on 13 January 1998. Reference numbers in this appendix match the
references listed in Appendix B.
