The European Satellite Navigation Competition (Galileo Masters), now in its fifth year, is seeking the best ideas for satellite navigation applications from companies, entrepreneurs, research institutes, universities, and individuals.
This year’s contest will culminate with an awards ceremony in the Munich Residenz, Munich, Germany on Tuesday, October 21, 2008.
NovAtel Inc. has launched its new GL1DE technology, the latest enhancement to the Calgary, Alberta, Canada–based company’s high-precision OEMV GNSS product line.
GL1DE is a relative pseudorange/delta-phase filter enhancement available in the coompany’s OEMV 3.400 firmware. The new technology is targeted for agricultural guidance applications in which pass-to-pass repeatability and elimination of position “jumps” is critical.

Hemisphere GPS has released an OEM development kit for its Eclipse dual-frequency GPS receiver technology.
Development kits allow product designers and system integrators to more easily access and test all of the available features on an Eclipse board, simplifying the effort needed to reach a proof of concept and shortening the time required to bring a product to market.

The European Space Agency (ESA) has awarded a contract to IfEN GmbH to develop a “New Generation” receiver breadboard for use at the European Geostationary Navigation Overlay Service (EGNOS) Ranging and Integrity Monitoring Stations (RIMS).
The RIMS New Generation breadboard will be capable of receiving the new L2C and L5 signals, the Galileo E1, E5ab, and E6 signals and the GLONASS L1 signal in addition to GPS L1 and L2P signals.

The Nationwide Differential Global Positioning System (NDGPS) program has been salvaged from the political limbo in which it has resided for more than a year.
Following completion of an assessment by the U.S. Department of Transportation (DoT), the agency has decided to continue full NDGPS operations. Currently, 86 stations are operating with support from three federal agencies: the U.S. Coast Guard (USCG, 39 sites), the Army Corps of Engineers (9 site), and the DoT (38 sites operated and maintained by the USCG under contract).

u-blox LEA-5TSwiss GNSS chip manufacturer u-blox has introduced a new precise timing GPS module, the LEA-5T, precise timing at the CTIA Wireless 2008 conference taking place this week in Las Vegas.
Based on the company’s 50-channel, fifth-generation chipset technology, the LEA-5T is intended for such applications as telecom network synchronization, use in WiMAX base stations for home-based broadband networks, and data communication among geographically dispersed systems and devices such as NTP servers.
