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.”

Interoperability in a world of multiple global navigation satellite systems—everybody talks about it, but not much has been done about it in practice. The Japanese Aerospace Exploration Agency (JAXA) hopes to change that with a five-year campaign demonstrating the benefits and opportunities of maximizing the use of the more than 100 GNSS space vehicles that will be operating over the Asia-Oceania region in the next decade. (See accompanying satellite-visibility graphic).

Stanford GNSS Monitor Station AntennaInitial 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.

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.”

Illustration of GLONASS-K satelliteA provisional specification for the planned GLONASS CDMA signal has been defined and is available to receiver manufacturers interested in experimenting with the demonstration signal that will be broadcast from the GLONASS-K satellite to be flight-tested later this year.
Mark Shmulevich, head of business development for Russian Space Systems (RSS), extended the offer at the Asia Pacific Economic Cooperation GNSS Implementation Team (APEC-GIT) meeting in Seattle, Washington, this week. RSS is an amalgamation of 10 former Russian federal state unitary enterprises — that is, government corporations — and other Russian institutes and agencies established last year, with the former Russian Institute of Space Device Engineering (RISDE) serving as the lead.

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.

The decades of successful exploitation of satellite navigation systems GPS and GLONASS have confirmed their unique status as a basic resource for reliable worldwide, all-weather, all-season, round-the-clock positioning and timing. Nevertheless, the permanently widening sphere of their practical applications — as well as challenging requirements emerging from potential new users — give these systems a momentum for further evolution and progress.

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.
