Abstract
The report look at techniques to perform the localization of SARSAT 406 MHz distress beacons using geostationary satellites. After reviewing the characteristics of the distress beacon transmitters, the main specifications of the GOES satellites are described as they can be assumed as typical geostationary satellites for this application. A brief review of the geolocation techniques is presented and an in-depth analysis is conducted on the time difference of arrival technique. The analysis covers the impact of the Earth's flatness, channel impairments and satellite geometry. The delay estimator performance is expressed as a function of signal-to-noise ratio and circular error probability. The overall system performance is directly related to the performance of the delay estimator. TRUNCATED
