50th Civil GPS Service Interface Committee (CGSIC) Meeting

The 50th Civil GPS Service Interface Committee (CGSIC) Meeting will be held on Monday, September 20 and Tuesday, September 21 at the Oregon Convention Center in Portland just before the 2010 Institute of Navigation GNSS conference at the same location.

For the first time, the CGSIC meeting will be hosted by ION and the CGSIC plenary session will be on the main agenda of the larger conference.

CGSIC subcommittee meetings will be held on Monday and the plenary session on Tuesday, a reversal of the usual order.

Early View on GPS SVN62: As Well As Might Be Expected

GPS IIF satellite on Boeing assembly line

The first GPS IIF satellite (SVN62/PRN25) is on orbit and doing well, despite some well-publicized speculation about higher-the-expected range residuals detected by researchers at the German Aerospace Center (DLR).

Help from Above

During flight testing, Boeing technical personnel have historically used a differential GPS (DGPS) system as the position truth reference for validating various production systems on the airplane. The majority of those tests occur on or near remote runways to capture specific environmental conditions.

[Updated July 22, 2010] Air Force officials at the GPS Wing have confirmed that higher-the-expected range residuals detected by researchers at the German Aerospace Center (DLR) are appearing in signals transmitted by the first GPS IIF satellite, designated SVN/62/PRN25.

But the Air Force and Boeing Space and Intelligence Systems, which built the spacecraft, point out SVN62 is currently performing within specifications, and the signal phenomenon does not appear likely to have any significant effect on GPS positioning when the satellite is declared operational.

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.
