Global Navigation Satellite Systems Engineering, Policy, and Design
Dee Ann DivisInside GNSS coverage of the GPS intellectual property dispute between the United Kingdom and the United States has won the magazine’s Washington correspondent, Dee Ann Divis, another journalism award — this one from the Military Reporters & Editors Association.

As engineers painstakingly work their way through tests of the first full operational capability (FOC) Galileo satellite at the European Space Agency’s European Space Research and Technology Center (ESA/ESTEC) in Noordwijk, The Netherlands, European space sources have acknowledged that the new-generation spacecraft’s maiden voyage will not occur until December 28, and even that date looks highly unlikely.

Locata’s VRay Orb-80 antennaThe Air Force Institute of Technology (AFIT) and Locata Corporation, based in Canberra, Australia, have announced the signing of a co-operative research & development agreement (CRADA) to build and demonstrate new Locata multipath mitigation technology for use in GPS receivers. This cooperation is expected to leverage many years of proprietary Locata ground-based technology development to bring completely new capabilities to satellite-based GPS receivers.

√ Not only has century-old American motorcycle manufacturer Harley Davidson used consumer focus groups for the first time to develop its newest “hogs,” it has responded to customers with a voice-activated touch-screen GPS unit, the first on a production model. Now the Easy Riders don’t have to wend their way to trouble, they can ask their chopper where to go.
Air Force officials should get more cost and user information and determine how many GPS satellites they will support before making decisions about revamping the navigation system, the Government Accountability Office (GAO) has told Congress.
Although an Air Force report about program options was “a good starting point, more information on key cost drivers and cost estimates, and broader input from stakeholders would help guide future investment decisions,” the GAO wrote in an assessment of the defense agency’s analysis.

BeiDou-2 Is Born
The year before the main release, China surprised the global community when it published just a test version of the promised ICD for the BeiDou-2 B1 open signal. In this document, the modulation scheme for the signal was confirmed and the pseudorandom code generator for the ranging signal was described.
After skipping a year, the Munich Satellite Navigation Summit will reconvene on March 25, 26 and 27 in Der Residenz, München in Bavaria. The 2014 event will include a parallel track on Copernicus, the European Commision’s Earth Observation Program. Registration is now open at the web address below.
The opening plenary panel at 5 p.m. on Tuesday will discuss "GNSS-New Challenges."
The technical program will cover:
