Publikováno v: ION International Technical Meeting 2016
ION International Technical Meeting 2016, Institute of Navigation, Jan 2016, Monterey, United States

International audience; This paper proposes threat models (TM) for Galileo E1C, the pilot component of the E1 Open Service signal, (CBOC(6,1,111⁄) modulation) and Galileo E5a (BPSK(10) modulation) signals, as they are the Galileo signals that will

Estimation of GNSS Signals’ Nominal Distortions from Correlation and Chip Domain

Autor: Pagot, Jean-Baptiste, Thevenon, Paul, Julien, Olivier, Gregoire, Yoan, Amarillo-Fernandez, Francisco, Maillard, Denis

ION ITM 2015, Proceedings of the 2015 International Technical Meeting of The Institute of Navigation, ION, Jan 2015, Dana Point, California, United States

International audience; This paper analyses two ways to investigate nominal distortions of GNSS signals. Firstly, these perturbations can be observed from the correlation function point of view and secondly, from the CDO (Chip domain observable) whic

Processing Technique and Performance of the Observation of Evil Waveform in the Chip Domain

Autor: Thevenon, Paul, Pagot, Jean-Baptiste, Julien, Olivier, Tessier, Quentin

Publikováno v: ESA Navitech 2014, 7th ESA Workshop on Satellite Navigation Technologies
ESA Navitech 2014, 7th ESA Workshop on Satellite Navigation Technologies, European Space Agency, Dec 2014, Noordwijk, Netherlands

International audience; This paper focuses on the Chip Domain Observable, a particular observation of the GNSS signal that is done in the time-domain, directly on the digitized samples at the output of the RF front-end of a GNSS receiver. With such o

ION GNSS+ 2014, 27th International Technical Meeting of The Satellite Division of the Institute of Navigation, Institute of navigation, Sep 2014, Tampa, Florida, United States

International audience; Evil Waveform (EWF) are signal distortions that can create persistent errors (bias) on the pseudo-range measurement of several meters. They are of particular interest for differential GPS users and for safety critical users. F
