At 23:53 on June 2, China successfully launched the 4th BeiDou navigational satellite into the pre-designated orbit with the "Long March 3C" carrier rocket at the Xichang Satellite Launch Center, symbolizing that China has made another important step forward in building the BeiDou (COMPASS) Navigation Satellite System. The construction of COMPASS follows the principles of openness, independency, compatibility, and gradualness.

Reading between the Lines: GPS & 2010 National Space Policy

Reading between the Lines: GPS & 2010 National Space Policy

A new National Space Policy announced this week (June 28, 2010) by the White House appears to do more than elevate GPS in the pantheon of U.S. space programs.

The five paragraphs on space-based positioning, navigation, and timing (PNT) systems prominently enshrine the U.S. GNSS system in the 18-page document: GPS is the only program called out by name in the policy’s section on “Foundational Activities and Capabilities.”

Obama’s National Space Policy Authorizes Use of Foreign GNSS Services to Strengthen GPS

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.”

GNSS to Star in FAA’s NextGen Air Traffic System

Next Generation Air Transportation System (NextGen) Concept

The Federal Aviation Administration (FAA) accelerated its move toward a Next Generation Air Transportation System (NextGen) with contracts awarded to Boeing, General Dynamics and ITT on May 26 and performance requirements for aircraft tracking equipment announced May 28.

NextGen, to be completed by 2025, will rely heavily upon GNSS to increase capacity, efficiency, and safety in the National Air Space (NAS) while reducing adverse environmental effects.

Deselecting Unavailability

Deselecting Unavailability

Only a decade ago, but a world away: 2000.

The last year of the old century that everyone thought was the first of the new.

When flying was still a delight, rather than a worrisome bother.

When the expected — a global Y2K bug–bitten IT meltdown — didn’t happen, and the much-anticipated but still-unexpected did: the United States turned off GPS selective availability.
