High accuracy GNSS based navigation in GEO

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano, Paul David Blunt, Endrit Shehaj

Although significant improvements in efficiency and performance of communication satellites have been achieved in the past decades, it is expected that the demand for new platforms in Geostationary Orbit (GEO) and for the On-Orbit Servicing (OOS) on the ex ...

Prospective head motion correction using FID-guided on-demand image navigators

Rolf Gruetter, Reto Meuli, Tobias Kober, Gunnar Krüger, Tom Hilbert, Bénédicte Marie Maréchal, Guillaume Bonnier, Maryna Volodimirivna Waszak, Pavel Falkovskiy

PURPOSE: We suggest a motion correction concept that employs free-induction-decay (FID) navigator signals to continuously monitor motion and to guide the acquisition of image navigators for prospective motion correction following motion detection. METHODS: ...

Availability and ranging error analysis for a GPS L1/L5 receiver navigating to the Moon

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano, Paul David Blunt, Ban Wang, Endrit Shehaj

Global Navigation Satellite System (GNSS) based navigation is already adopted in Low Earth Orbit (LEO), where the presence of strong GNSS signals and the good relative geometry between the receiver and the transmitters enable precise orbit determination. H ...

Structured transparent low emissivity coatings with high microwave transmission

Andreas Schueler, Luc Burnier, Olivia Valérie Charlotte Bouvard

In order to reduce the energy consumption of buildings, modern windows include metal-containing coatings. These coatings strongly attenuate the microwaves used for mobile communications. Here, we present a novel approach to improve radio signal transmissio ...

GPS Based Navigation Performance Analysis within and beyond the Space Service Volume for Different Transmitters’ Antenna Patterns

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano, Paul David Blunt, Endrit Shehaj

In recent years, global navigation satellite system (GNSS)-based navigation in high earth orbits (HEOs) has become a field of research interest since it can increase the spacecraft’s autonomy, thereby reducing the operating costs. However, the GNSS availab ...

Derivation of the Cramér-Rao Bound in the GNSS-Reflectometry Context for Static, Ground-Based Receivers in Scenarios with Coherent Reflection

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix

The use of the reflected Global Navigation Satellite Systems’ (GNSS) signals in Earth observation applications, referred to as GNSS reflectometry (GNSS-R), has been already studied for more than two decades. However, the estimation precision that can be ac ...
