Global Navigation Satellite Systems Engineering, Policy, and Design
The Trimble Dimensions conference covers real-world applications of positioning technology in the survey, construction, mapping and GIS, utility, mobile mapping, mobile resource management, GNSS infrastructure and construction asset management industries.
Of particular interest to Inside GNSS readers will be the Infrastructure Track; it includes high-accuracy positioning information for a wide variety of applications and industries.

Interoperability in a world of multiple global navigation satellite systems—everybody talks about it, but not much has been done about it in practice. The Japanese Aerospace Exploration Agency (JAXA) hopes to change that with a five-year campaign demonstrating the benefits and opportunities of maximizing the use of the more than 100 GNSS space vehicles that will be operating over the Asia-Oceania region in the next decade. (See accompanying satellite-visibility graphic).

A new U.S. National Space Policy announced today (June 28, 2010) by the White House says that foreign GNSS services may be used “to augment and strengthen the resiliency of GPS.”
In a document that underlines the Obama administration’s intention to rely more on international cooperation in space-related activities and “energize competitive domestic industries to participate in global markets,” the new policy reaffirms recent efforts “to engage with foreign GNSS providers to encourage compatibility and interoperability, promote transparency in civil service provision, and enable market access for U.S. industry.”

Solar Dynamics Observatory (SDO) spacecraft. NASA imageThis year’s Space Weather Workshop — held April 27–30 in Boulder, Colorado — reflected a heightened interest in the space environment due to solar effects on GPS and other GNSSes. A solar storm is suspected to have caused the anomaly in Intelsat’s Galaxy 15 communications satellite that carries a transponder for the GPS Wide Area Augmentation System (WAAS),
