Comparison of L1 and L5 Bands GNSS Signals Acquisition

Nowadays, civil Global Navigation Satellite System (GNSS) signals are available in both L1 and L5 bands. A receiver does not need to acquire independently the signals in both bands coming from a same satellite, since their carrier Doppler and code delay ar ...

Feature article: High sensitivity acquisition of GNSS signals with secondary code on FPGAs

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

The modern global navigation satellite systems (GNSS) signals, such as the Global Positioning System (GPS) L5 and L1C, and Galileo E5 and E1, have brought several innovations: the introduction of a pilot channel that does not contain any data to allow very ...

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 ...

FFT Splitting for Improved FPGA-Based Acquisition of GNSS Signals

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

With modern global navigation satellite system (GNSS) signals, the FFT-based parallel code search acquisition must handle the frequent sign transitions due to the data or the secondary code. There is a straightforward solution to this problem, which consis ...

FEASIBILITY STUDY OF GNSS AS NAVIGATION SYSTEM TO REACH THE MOON

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Reaching the Moon poses very strict requirements in terms of performance, flexibility and cost for all the spacecraft subsystems. These requirements become more stringent if the mission is designed to be accomplished using a small spacecraft. The navigatio ...

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 ...
