Global Positioning System Control/User Segments. System/Design Trade Study Report

Abstract

This Trade Study Report documents the decision rationale used to resolve configuration design approaches. The trade studies presented are the major decision efforts required during this concept Definition Phase. The design of the Global Positioning System (GPS) for Phase I required evaluation of alternatives for a variety of design problems. The trade studies contained in this report are: (1) Satellite Memory Loading, -- (2) Satellite Orbits, -- (3) Monitor Station Sites, -- (4) Control Segment Computers, -- (5) User Segment Computer, -- (6) User Cost/Performance, -- (7) User Ionospheric Model, -- (8) User Ephemeris Model, -- (9) Ephemeris Determination.
