QZSS satellite separaes from the launcher (photo by Mitsubishi Heavy Industries)(UPDATED September 27) Japan’s first quasi-zenith satellite launched successfully from the Tanegashima space center on September 11, 2010 and reached its quasi-zenith orbit on Monday, September 27.
Michibiki means to guide or lead the way, appropriate for the first entry into Japan’s satellite augmentation program that will vastly improve GNSS accuracy over Japan and the rest of East Asia.

Few would mistake Oregon for the beating heart of GNSS. Still, for a medium-sized U.S. metro area in the Pacific Northwest, Portland and Oregon’s I-5 corridor has enough relevant involvement with the industry to justify hosting the Institute of Navigation’s 2010 GNSS conference and exhibition.
Oregon has FLIR Systems, Cloud Cap Technology, TriQuint, Intel, Garmin and Inside GNSS magazine.

A completely GPS-based navigation solution is generally not feasible in GNSS signal–challenged environments such as urban canyons. However, even in these difficult environments a partial set of GPS signal measurements may still be available. For instance, one or two satellites are generally still visible even in dense urban canyons.
