The 50th Civil GPS Service Interface Committee (CGSIC) Meeting will be held on Monday, September 20 and Tuesday, September 21 at the Oregon Convention Center in Portland just before the 2010 Institute of Navigation GNSS conference at the same location.
For the first time, the CGSIC meeting will be hosted by ION and the CGSIC plenary session will be on the main agenda of the larger conference.
CGSIC subcommittee meetings will be held on Monday and the plenary session on Tuesday, a reversal of the usual order.
Fifth Beidou-2 satellite launched. Xinhua/Du Cai photo[Updated August 1, 2010] China’s state news agency has reported that the fifth Compass (Beidou-2) satellite — the system’s first inclined geostationary orbit (IGSO) spacecraft — was launched successfully at 5:30 a.m. Sunday (August 1 — local time) from Xichang Satellite Launch Center in southwestern Sichuan Province
This was the third Compass satellite put into orbit this year, following launches in June and January 2010.

At 23:53 on June 2, China successfully launched the 4th BeiDou navigational satellite into the pre-designated orbit with the "Long March 3C" carrier rocket at the Xichang Satellite Launch Center, symbolizing that China has made another important step forward in building the BeiDou (COMPASS) Navigation Satellite System. The construction of COMPASS follows the principles of openness, independency, compatibility, and gradualness.

Late in May, China implemented new standards aimed at preventing "state secrets being disclosed and uncertified maps published online." A major component to this push was a requirement that all online mapping services are operated with a license. The first 18 companies, of the ones that applied for a license, have been approved.

Alaska Air graphicAlaska Airlines demonstrated next-generation GPS-aided flight procedures last week (July 23) during a test flight over Puget Sound, Washington, that burned less fuel and reduced emissions by 35 percent compared to a conventional landing.
The flight was part of Alaska Air Group’s “Greener Skies” project at Seattle-Tacoma International Airport (Sea-Tac) focused on using satellite-based guidance technology to fly more efficient landing procedures that will reduce environmental impacts in the region.

GINA On-Board Unit (OBU)For at least the past two decades, managing traffic on Europe’s road networks has been a growing concern for European policy makers and citizens alike. While demand for transport has consistently increased over the years, Europe’s road network capacity has failed to keep pace, leading to increasing levels of congestion and pollution.
