ABSTRACT A single‐frequency GPS receiver was launched with the Extreme Ultraviolet
Explorer (EUVE) mission in the summer of 1992. The low altitude of the EUVE and the …

This dissertation describes the methods and implementation of extended Kalman filtering,
backwards smoothing and carrier phase integer ambiguity resolution for the problem of …

We present four integration methods which exploit efficient numerical techniques for orbit
propagation. The methods have been selected to compare the strategy of using first order …

In this paper we describe a new method useful for autonomous onboard estimation for
satellites in LEO. The method employs symplectic integration which provides very high …

Autonomous On-Board Batch Filter for Near Circular Orbit Determination ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect …

Um algoritmo simplificado e compacto com baixo custo computacional fornecendo precisão
em torno de dezenas de metros para determinação de órbita de satélites artificiais em …

In an effort to estimate precise satellite ephemeris in real-time on board a satellite, the
Goddard Space Flight Center GSFC created the GPS Enhanced Orbit Determination …

This work is concerned with orbit determination using GPS signals. An especial case of
truncated arcs assuming that GPS receiver data, which is available only when the satellite …

This work is concerned with short arcs orbit determination using GPS signals. A special case
of truncated arcs assuming that GPS data is only available when the satellite carrying the …
