Europe Weighs Mandate of Galileo Chips in Mobile Phones

June 30, 2014By

The European Commission is considering a requirement for mobile phones, and perhaps other portable devices such as tablets, to be equipped with Galileo receivers that would automatically send location data as part of any emergency call to 112. E112 is a location-enhanced version of the 112 universal European emergency services number via telephone, equivalent to 911 in the United States, in which the... read more

Occupy Media Space Now EGNOS and Galileo Mission

June 29, 2014By

By Peter de Selding The message to the recent European Space Solutions conference in Prague was simple enough: EGNOS is here, so let’s use it; Galileo is almost here, so let’s promote it. Neither task is straightforward. Take the European Geostationary Navigation Overlay Service (EGNOS), the European piece of a near-global network of terminals on geostationary satellites linked to networks... read more

eDLoran: The Next-Gen Loran

Potential GNSS Back-up Improves to GPS-Level Accuracy
A new enhanced differential Loran system demonstrates 5-meter accuracy not achievable by the current DLoran system, and requires less expensive reference stations. A prototype tested in Rotterdam’s Europort area uses standard mobile telecom networks and the Internet to reduce correction data latency — a key source of error — by one to two orders of magnitude. read more

LightSquared-spectrum-W

The U.S. Federal Communications Commission convened a June 20 workshop on “GPS Protection and Receiver Performance” whose bite turned out to be far less than its bark had led some in the GPS industry to fear. The hastily assembled workshop — three weeks notice was given — appeared at first notice to derive from the call for “GPS receiver performance standards”... read more

By Gerhard Beutler, Rolf Dach, Urs Hugentobler, Oliver Montenbruck, Georg Weber, and Elmar Brockmann What Happened: On April 1, 2014, at 21:15 UTC, all GLONASS satellites started to transmit wrong Broadcast Messages (BM) as previously reported by GPS World. The satellite positions derived from these BM were wrong by up to ± 200 kilometers in each of the three coordinates... read more

ESA Recognizes First Galileo Navigation Fixes

Billions of satnav position fixes are performed daily, but determining your place in the world using Europe’s Galileo system is quite new. Because of this, in March the European Space Agency (ESA) offered to issue certificates for the first 50 Galileo fixes. Responses to the offer came from around the world. While half the applications came from Galileo’s home continent,... read more

StellaNGC_Simulator-O

M3 Systems is now offering the StellaNGC multi-constellation GNSS simulator based on the National Instruments (NI) vector signal transceiver. The simulator is designed for the testing of satellite navigation receivers for GPS, GLONASS, Galileo, and EGNOS/WAAS. It is designed to improve performance, scalability, and versatility, and reduce cost over existing navigation test solutions. GNSS is the predominant technology today for... read more

EuroGeographics to Create Expert Group in GNSS Positioning

June 20, 2014By

Members of EuroGeographics are creating a European platform for networking, sharing best practices, and exchanging expertise on GNSS positioning. Plans for the new Positioning Knowledge Exchange Network (KEN) were revealed at the association’s recent Extraordinary General Assembly following a proposal by the Head Office for Geodesy and Cartography, Poland. Its focus will include: maintaining a network of experts in satellite... read more
