Real time orbit determination using GPS navigation solution

Abstract: This work analyses a real time orbit estimator using the raw navigation solution provided by GPS receivers. The estimation algorithm considers a Kalman filter with a rather simple orbit dynamic model and random walk modeling of the receiver clock bias and drift. Using the Topex/Poseidon satellite as test bed, characteristics of model truncation, sampling rates and degradation of the GPS receiver (Selective Availability) were analysed.

“…Then, it goes to orbital maneuvers based in low thrust (Casalino and Colasurdo 2002;Casalino et al 1999;Brophy and Noca 1998;Zee 1963;Lion and Handelsman 1968;Prado 2007, 2008;Macau 2000;Macau and Grebogi 2006), swing-by techniques (Flandro 1966;Marsh 1988;Farquhard and Dunham 1981;Prado and Broucke 1995;Prado 2007;Gomes et al 2013;DeMelo et al 2009), and even gravitational capture (Belbruno and Miller 1993;Pierson and Kluever 1994;Neto and Prado 1998). It covers also some more applied concepts, like searches for specific orbits (Chiaradia et al 2003;Carvalho et al 2010;Araujo et al 2012;Domingos et al 2008;D'Amario et al 1982;Farquhar et al 1985;Gomes and Domingos 2015;Salazar et al 2015aSalazar et al , b, 2014Salazar et al , 2012Gomes et al 2007).…”
