Range Navigation Using the TIMATION II Satellite

Abstract

The TIMATION (Time Navigation) technique of passive ranging can be employed to provide a worldwide navigation and time-transfer service. Passive ranging is accomplished by measuring the time difference between electronic clocks located within the satellite and the navigator's receiver. Navigation results were obtained with a prototype system consisting of the TIMATION 2 satellite and four ground stations. The results indicate a CEP position-fixing capability of 33 meters (100 feet) using dual-frequency range measurements. The analysis of the data includes ionospheric refraction, instrumentation error, and the effect of satellite trajectory position error in both the observed and predicted regions. (Author)
