Abstract:

This report describes the system configuration trade studies analyses, defines critical system parameters, documents the results and selects a high altitude navigation system concept. During this Task 1 effort two basic system configurations were analyzed and their sensitivity to landmark parameters and tracking schedule established. The first of these configurations is based on the Interferometric Landmark Tracker ILT studied and tested under the Autonomous Navigation Technology ANT Contracts the second configuration adds a passive ranging capability to the ILT. These systems are described in Section 2.0. The results obtained using a covariance analysis program are presented in Section 3.0 and indicate the feasibility of the Passive Ranging Interferometer Sensor PRAIS concept. Critical parameters are identified in Section 4.0. Section 5.0 describes the system selection.
