High sensitivity GPS receivers have extended the use of GNSS navigation to environments which were previously deemed unsuitable for satellite signal reception. Under adverse conditions the signals become attenuated and reflected. High sensitivity receivers achieve signal reception by using a large number of correlators and an extended integration time. Processing the observation data in dynamic...
Improved operational autonomy is required for the operation of any single satellite within a LEO satellite network. One onboard function, which is an interesting candidate to be implemented with an increased level of onboard autonomy is apparently the navigation function, which is in charge of the determination of the instantaneous satellite orbital position and attitude. This paper aims to dem...

Auto-navigating of unmanned aerial vehicles (UAV) in the outdoor environment is performed by using the Global positioning system (GPS) receiver. The power of the GPS signal on the earth surface is very low. This can affect the performance of GPS receivers in the environments contaminated with the other source of radio frequency interference (RFI). GPS jamming and spoofing are the most serious a...
Recording the movement of objects or persons with GPS-technology has been widely adopted. So called GPS traces are used for enriching travel diaries (Wolf et al. 2001), for learning significant places (Ashbrook and Starner 2003), for monitoring animal movement (Steiner et al. 2000) or for building road maps (Cao and Krumm 2009). While all of the mentioned applications rely on GPS traces, the me...
