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

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).

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.

Air Force Investigating Residuals in GPS IIF Signals

[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

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.
