Abstract:

This report, Volume 5 of the High Altitude Navigation System HANS Study, presents the sensitivity analyses carried out on the selected HANS system. Two Passive Range Interferometer Sensor PRAIS sensitivity analyses were conducted, one assuming atomic clock control of radar PRI, and one assuming crystal clock stability typical of MTI radars. Sensitivity data for the five study orbits is presented in terms of percent change in position error from the position error under nominal system error conditions. In these analyses two landmarks were tracked simultaneously, one with both passive ranging and interferometer landmark tracker ILT - the other with only the ILT.
