The vulnerability of GNSS to radio frequency interference and spoofing becomes more and more of concern for navigation applications which require a high level of accuracy and reliability…

On November 18, 2015, the Quasi-Zenith Satellite System Service Co., Ltd. (QSS) conducted an experiment in Kyoto, Japan using a quasi-zenith satellite system…

When you think about it, GNSS is miraculous. Actually, like most magic, it is best for most people not to think too much about it. They just accept that today’s cars know…

This paper introduces a summary of the GEMNet system, and presents two sets of results. Firstly, characteristics of interferers observed operationally along with…

The GNSS downstream market continues to be one of the most promising markets in terms of European growth, with anannual growth rate of the global…

The territory of Bulgaria is one within the Balkan Peninsula region with active tectonics and seismotectonics. A number of geodynamical investigations try to give an…

This document presents some results of the scientific research conducted by Training on EGNOS-GNSS in Africa (TREGA) laboratory members concerning the…

With fully operational GLONASS, scope for use of Multi-GNSS has increased as GLONASS may be used along with GPS. This paper describes a study from India on the use of GLONASS with GPS for position solution. Increasing number of GLONASS satellite signals were used sequentially…

Operational and emerging Global Navigation Satellite Systems (GNSS) GPS, GLONASS, Galileo and others provide high-accuracy determination of position, velocity and time for land, marine, airborne and other kinds of users.

Because receiver autonomous integrity monitoring (RAIM) techniques are based on measurement redundancy, multi-constellation signals will have a positive impact in principle on the integrity monitoring performance of RAIM algorithms. Increasing reliability and resilience of next generation…
