Global Navigation Satellite Systems Engineering, Policy, and Design
Dr. Andrey Soloviev, QunavGNSS and inertial technologies have a complicated mutual history.
Once competitors for navigation and positioning applications, they now appear ever more frequently in complementary roles — often within the same solution or system design.

John Porcari, US DoT Deputy SecretaryU.S. Deputy Secretary of Transportation John Porcari told a congressional committee today (February 8, 2012) that the expenditure of “substantial federal resources” in assisting LightSquared to gain approval for its terrestrial wireless broadband system was “unusual” yet “merited,” but that “further investment cannot be justified at this time.”

The European Space Agency (ESA) today (February 2, 2012) signed a contract to build a further eight Galileo satellites, alongside other agreements to modify Europe’s Ariane 5 launcher to carry four navigation satellites at a time.
The signing took place at the European Commission’s center in London, England, in the presence of European Commission Vice-President Antonio Tajani and UK Universities and Science Minister David Willetts.

Russia’s GNSS program plans to launch three more satellites in the first half of 2012 as part of a 20.55 billion ruble (US$655 million) federal target program budget for the coming year, the Roscosmos space agency announced on January 17.

A Senate investigation into how the Federal Communications Commission (FCC) handled a request to rezone spectrum adjacent to GPS frequencies for LightSquared’s powerful wireless network will continue whether the FCC nixes the plan or not.
Sen. Chuck Grassley, R-Iowa, has been looking into whether the FCC fast-tracked its review of the Virginia firm’s proposal to build a 4G broadband network with signals that would be, tests now show, powerful enough to interfere dramatically with GPS receivers.

In an effort to improve constellation sustainment, on or about Feb. 1, 2012, SVN-49 will resume transmitting an L-band signal using PRN24 as a test asset, according to the U.S. Air Force Space Command. Upon completion of the test event, SVN-49 will once again be decommissioned from active service. PRN24 will then once again be available for future satellite service.

GPS and other space systems fare well in the Department of Defense (DoD) strategic budget initiative outlined today (January 26, 2012) by U.S. civil and military officials.
The comments reflected policy decisions laid out in “Defense Budget Priorities and Choices,” an introduction to a strategic guidance intended to plot the course of the Pentagon over the next five years. Modernization of the Global Positioning System will be “protected” financially, according to the document.

istock photoA U.S. Supreme Court opinion released this week (January 23, 2012) ruled that warrantless GPS-aided monitoring of a suspect violated the Constitution’s Fourth Amendment protection against “unreasonable searches and seizures."
But it will probably not be the court’s last word on the subject and may, in fact, provide Congress and state legislatures with enough incentive to address the subject more fully than they have to date.

Why Washington continues to talk about deficits while the country is talking about jobs and foreclosures is kind of a mystery, but let’s play along.
Following the failure of Congress’s would-be budget-cutting committee that wasn’t so super, the Department of Defense is facing about $500 billion in mandatory cuts over the next 10 years.
