Satellite orbit determination using Automatic Identification System (AIS) data

点击翻译按钮获取中文摘要

Satellite orbit determination (OD) is the method of determining the position and velocity of an orbiting object using various observations and measurements. Orbit determination is important for modern space operations and satellite applications, such as geodesy, navigation, communications, and many other areas. Autonomous orbit determination using only on-board measurements is desired for some spacecraft to guarantee independence from the ground facilities. The Automatic Identification System (AIS) is a communications system designed primarily for the purposes of maritime safety. AIS data provides a source of information which can be used to spatially represent vessel movements within the receiving range of transmissions. The objective of this research project is to develop effective techniques for precise orbit determination using AIS data from ships. The methods developed through this project can be applied to satellites with no on-board orbit determination solution.
