A Galileo E1b,c RF Front-End Optimized for Narrowband Interferers Mitigation

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Davide Manetti, Giuseppe Zamuner

The current Search and Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the first 121.5MHz/( ...

A Low-Power RF Front-End Architecture for an L1/L2CS GPS Receiver

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

With the apparition of several new civilian signals in the years to come, there will soon be great demand for multifrequency receivers. As soon as two signals will be available, users will be able to correct the ionospheric error, the main source of error ...

Pedestrian navigation method and apparatus operative in a dead reckoning mode

Quentin Ladetto

A displacement of a pedestrian is determined from his or her accelerations by detecting accelerations which is substantially non vertical, determining a characteristic feature in the detected accelerations correlated with a step frequency, determining the ...

Performance Analysis of Mobile Station Location Using Hybrid GNSS and Cellular Network Measurements

Pierre-André Farine, Cyril Botteron, Elham Firouzi

Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...

GSM-Distributed RTK for Precise Analysis of Speed Skiing

Jan Skaloud, Bertrand Merminod, Hervé Gontran

The applications to dynamic sports for an accurate analysis of trajectories represent a new perspective for carrier phase-based GPS positioning. Introduced in competitive skiing, the GPS technique provide all the qualitative data for a complete analysis of ...

Challenging EGNOS in the Swiss Alps

Pierre-Yves Gilliéron

In view of the operational validation of EGNOS, some early tests are being performed with the EGNOS System Test Bed (ESTB). This prototype has been broadcasting an EGNOS-like signal since early 2000. The performance of ESTB is reduced compared to the full ...

The EGNOS Integrity Concept: Evaluation of the Ionospheric Corrections

Within the validation work of EGNOS for civil aviation, it is interesting to analyze the transmitted corrections individually. In this paper, the ionospheric model of EGNOS is compared to the one determined by an independent organization (CODE). The contin ...
