Open House at the German Aerospace Center (DLR) near Munich, Germany.GNSS Signals 2009 will take place at the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany on Thursday and Friday, December 10-11 2009.
The free workshop will cover recent advances in GNSS signal design,
evolution of Galileo and other GNSSes and a number of GNSS signal processing and observation techniques. The presentations and papers will be in English.
Program committee cochair Jean-Luc Issler of CNES, the French space agency, said the first call for papers has gone out and abstracts are due before October 2, 2009.

Thalwil, Switzerland–based embedded GNSS receiver provider u-blox has announced the upgrade of its core CMOS technology to u-blox 6, with substantially reduced power requirements as the result of new "intelligent," user-selectable power management features. According to the company, these innovations enable significantly extended battery life for power-critical GPS applications.

Comments submitted to the Office of the U.S. Trade Representative (USTR) suggest that the Galileo program is finally nearing a decision on commercial use of specifications for its Open Service (OS), but U.S. officials remain concerned that this nation’s equipment manufacturers not be placed at a competitive disadvantage. Meanwhile, Galileo simulators appear to finally be reaching receiver manufacturers, despite the absence of official approval.

GPS Networking, of Pueblo, Colorado, has launched the VGLCDLA30RPDC, a variable gain GPS in-line amplifier with LCD display and push button control.
Featuring a range of 0–30 dB, the VGLCDLA30RPDC’s push button control can increase or decrease gain in increments of 1 dB, enabling operators to make precise adjustments quickly and view the output power at any given time for more efficient testing.
The unit operates on 110VAC or 220 VAC transformer (wall mount) and 240 VAC (United Kingdom). Connector options include types N, SMA, TNC, and BNC.

Paul Verhoef, programme manager of EU Satellite Navigation Programs at the European Commission. ESA photo — S. Corvaja, 2009On June 15, the European Space Agency (ESA) signed contracts for launch services on the Galileo in-orbit validation (IOV) satellites as well as two additional contracts for “long lead items” needed to build the full operational capability (FOC) Galileo constellation of satellites.
The first contract, with Arianespace, will provide launch services for the four IOV Galileo satellites that will be placed in orbit by the end of 2010. Two Soyuz rockets, each carrying two Galileo spacecraft, will launch from Europe’s Spaceport in French Guiana.
