GNSS to reach the Moon

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

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 satellite. The navigation ...

Calibration of the GNSS Signal Amplitudes in the Interference Pattern Technique for Altimetry

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

Global Navigation Satellite Systems signals can be used in bi-static radar systems in order to get altimetric measurements. With a single classic GNSS ground-based receiver processing the combination of the signals coming directly and after one reflection ...

An Efficient Time-frequency Algorithm for the Weak Signal Acquisition of Modernized GNSS Signals

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

The new GPS/Galileo/Compass signals use much longer code lengths and higher code frequencies than the GPS L1 C/A signal. As a result, they can provide improved ranging and anti-jamming performances. Unfortunately, their acquisition complexity is significan ...

Normalized GNSS Interference Pattern Technique for Altimetry

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

It is well known that reflected signals from Global Navigation Satellite Systems (GNSS) can be used for altimetry applications, such as monitoring of water levels and determining snow height. Due to the interference of these reflected signals and the motio ...

GNSS BASED ATTITUDE DETERMINATION SYSTEMS FOR NANOSATELLITES

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Attitude determination systems based on global navigation satellite systems (GNSSs) present several advantages, most of all, for very small satellites. GNSS receivers have low power consumption, limited mass, small volume, and are rel-atively inexpensive. ...

GNSS/INS/Star Tracker Integrated Navigation System for Earth-Moon Transfer Orbit

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

Over the last few years, new Global Navigation Satellite System (GNSS) applications have emerged that go far beyond the original objectives of GNSS which was providing position, velocity and timing (PVT) services for land, maritime, and air applications. I ...

Mapping with MAV: Experimental Study on the Contribution of Absolute and Relative Aerial Position Control

Jan Skaloud, Martin Rehak

This study highlights the benefit of precise aerial position control in the context of mapping using frame-based imagery taken by small UAVs. We execute several flights with a custom Micro Aerial Vehicle (MAV) octocopter over a small calibration field equi ...

Generalized Method of Wavelet Moments for Inertial Navigation Filter Design

Jan Skaloud, Stéphane Guerrier, Yannick Stebler

The integration of observations issued from a satellite-based system (GNSS) with an inertial navigation system (INS) is usually performed through a Bayesian filter such as the extended Kalman filter (EKF). The task of designing the navigation EKF is strong ...
