Abstract:

The Timation II satellite is an experimental model of a range and doppler measurement satellite navigation system sponsored by the Naval Air Systems Command. In this report the satellite is described briefly, along with the ranging concept and the range and doppler measuring equipment. The basic navigation equations for range, doppler, and simultaneous range and doppler measurements are developed, along with several alternate techniques depending upon the user equipment. An analytical expression is developed for experimentally determining the range error due to first-order ionospheric refraction. The system biases are identified with clock difference range bias and frequency difference doppler bias. An error analysis is performed to determine the influence of geometry and system noise upon navigation accuracy. Author
