2010 5th ESA Workshop on Satellite Navigation Technologies and European Workshop on GNSS Signals and Signal Processing (NAVITEC).
This paper presents an implementation of a post-process kinematic positioning technique similar to PPP (Precise Point Positioning) but based on a network of stations. This technique is independent of precise clock information because it estimates sat

In this work, a new GPS carrier phase-based velocity and acceleration determination method is presented that extends the effective range of previous techniques. The method is named ‘EVA’, and may find applications in fields such as airborne gravi

In this paper we present two solutions for isolating integrals of the centroid motion in a non-stationary stellar system under the ellipsoidal hypothesis with point-axial symmetry.

First CHAMP Mission Results for Gravity, Magnetic and Atmospheric Studies ISBN: 9783642535444
The availability of occultation measurements from GPS receivers on-board several Low Earth Orbiters (GPS/MET, CHAMP, SAC-C. . .) is opening new possibilities to the ionospheric sounding. In this context we will briefly describe several approaches dev

In this work we study a non-cylindrical point-axial symmetric stellar system model that verifies the Chandrasekhar postulates [1]. It explains the values for the centered moments of the peculiar velocities and the galactic rotation parameters, non po
