In his State of the Union address on January 25, President Obama held up the Global Positioning System as a prime example of government providing “cutting-edge scientists and inventors with the support that they need” to create world-leading, job-creating innovation.
The following day, the Federal Communications Commission (FCC) International Bureau approved a conditional waiver allowing LightSquared Subsidiary LLC to build tens of thousands of terrestrial transmitters for wireless communications in frequencies on either side of the GPS L1 band.

(Update June 15, 2011 Inside GNSS) Completion of Satellite Repositioing Optimizes GPS Constellation
By next June, the United States GPS constellation will attain the most optimal geometry in its nearly 33-year history. Over time, that means a more robust signal, more accuracy and more reliability in GPS-challenged environments.
The 50th Space Wing is in the middle of maneuvering six GPS satellites into more favorable positions. The two-phase operation, called "Expandable-24" is halfway to completion.

Forecasters at NOAA’s Space Weather Prediction Center (NOAA photo)The annual Space Weather Workshop will take place on April 26-29 2011 in Boulder, Colorado.
Program organizers call it the "meeting of science, research, applications, operations and users." The program highlights space weather impacts in several areas, including
communications, navigation, spacecraft operations, aviation, and
electric power.
Recent progress in large-scale modeling efforts will
be featured; while new developments in Sun-to-Earth coupled modeling systems
will also be a highlight.

The GPS program continues progress on several fronts — in space and on the ground.
During fall 2010, the U.S. Air Force and the Raytheon Company team developing the GPS Advanced Control Segment (OCX) successfully carried out an integrated baseline review (IBR) for the next-generation system on schedule.
When completed in 2015 under the current schedule, GPS OCX will deliver control segment enhancements designed to provide secure, accurate and reliable navigation and timing information to military, commercial and civil users.

Col. Bernard GruberThe GPS Directorate completed its second Annual GPS Enterprise Review (AGER) on December 17, concluding that the program has achieved major milestones in developing and deploying modernized GPS capabilities.
Col. Bernard Gruber, GPS program director at the Space and Missile Systems Center, Los Angeles Air Force Base, led his team through a Defense Acquisition Board (DAB) review chaired by Frank Kendall, deputy undersecretary of defense for acquisition, technology and logistics, and attended by other senior Department of Defense (DoD) officials.

GMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.
As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.
