GPS System Specification for Shipboard TACAN Replacement.
Abstract
This final report is the submission of Contract Data Requirements list (CDRL) A003 for GPS System Specification for Shipboard TACAN Replacement. This final report includes the GPS System Specification for Shipboard TACAN Replacement. This final report covers Tasks 1 through 12 of the contract. which are as follows: 1) Review Shipboard TACAN requirements, 2) Investigate existing data links, 3) Derive Differential (DGPS) technique and associated data link content, 4) Derive Pseudolite Signal Structure, 5) Review Existing UE Requirements Specifications. 6) Review of Shipboard Equipment Specifications, 7) Derivation of Flight Safety Concepts, 8) Derivation of CDU Entry and Display Requirements, 9) Derivation of Flight Instrument Interface Requirements, 10) Derive Shipboard Equipment Requirements, 11) derive DGPS UE Requirements, 12) Generation of a System Specification. The results of Tasks 1 through 7 and Task 10 were originally documented in CDRLs A001 and A002.1 Updates were made to the documentation of these tasks in this report based on more recently obtained information. The updated results of those tasks are contained in Sections 2.2 and 2.3 and Appendices II, IV and V of this report. Task 2 (Section 2.2) was updated to include Low Probability of Intercept (LPl) analysis of the JTIDS system and to derive new data link possibilities base on the results of that analysis. Appendix ll contains the derivation of the LPl analysis tools for defining LPl requirements. Appendix V was updated to include the LPI analysis for pseudolites.
