Orbital Filter Aiding of a High Sensitivity GPS Receiver for Lunar Missions

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

Recent studies have shown that weak Global Navigation Satellite System (GNSS) signals could potentially be used to navigate from the Earth to the Moon. This would increase autonomy, robustness and flexibility of the navigation architectures for future luna ...

ns-level time transfer over a microwave link using the PTP-WR protocol

Pierre-André Farine, Cyril Botteron, Jean-Pierre Aubry, Mathieu Paul Joseph Carlos Rico

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...

Acquisition of modern GNSS signals using a modified parallel code-phase search architecture

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

The acquisition of global navigation satellite system signals can be performed using a fast Fourier transform (FFT). The FFT-based acquisition performs a circular correlation, and is thus sensitive to potential transitions between consecutive periods of th ...
