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.”

GPS IIF Signals: Loud and Clear

Stanford GNSS Monitor Station Antenna

Initial analyses by researchers in the United States and Germany of the transmissions from the first GPS Block IIF satellite indicate generally strong and healthy signals, although the some aspects of the new L5 signal are drawing close attention.

The researchers’ efforts will be reported in two articles in the July/August issue of Inside GNSS magazine.

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.”

Lockheed Martin Team Completes Requirements Review for GPS IIIB Program

Lockheed Martin has announced successful completion of a key requirements review for the GPS IIIB satellite series under the U.S. Air Force’s next-generation GPS III Space Segment program.

Lockheed Martin Space Systems, Newtown, Pennsylvania, is working under a $3 billion development and production contract from the U.S. Air Force to produce up to 12 GPS IIIA satellites, with first launch projected for 2014. The contract includes a Capability Insertion Program (CIP) designed to mature technologies and perform rigorous systems engineering for the future IIIB and IIIC increments planned as follow-on procurements.

On the Air

On the Air

With the launch of the Delta IV rocket on May 27 from Cape Canaveral Air Force Station the first satellite (space vehicle number 62 or SVN62) of the latest GPS generation Block IIF (F, for “follow-on”) was carried into earth orbit — a major step with roots in the past.

Eight years ago in August 2002 the United States decided in coordination with the International Telecommunication Union (ITU-R) to transmit a new civil signal on a third frequency known as L5.

[Updated June 10] The U.S. Air Force announced today (June 10) that it has begun
testing the new operational L5 signal transmitted by the first GPS IIF satellite (space vehicle 1 or SV1 — designated SVN-62 in the overall GPS system), which was launched May 27.

On June 7, 2010, a team of experts from the German Aerospace Center (DLR) and Stanford University in California reported results of their tracking of the first navigation signals from the satellite, the pseudorandom noise code 25 (PRN25) on L1 and L2 — C/A and P(Y).

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.
