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.
