[Updated December 15, 2014] The eighth GPS Block IIF navigation satellite launched on October 29 has completed its operational checkout and was set to healthy and usable on Friday (December 12, 2014). This brings the number of satellites transmitting the L2C signal to 15 and those transmitting the L5 signal to 8. The next GPS-IIF satellite, IIF-9/SVN-70 is tentatively scheduled for launch in March of 2015.

Heidi Shyu, assistant secretary of defense for acquisition, logistics and technologyPushed by Congress to upgrade to M-code, the U.S. Army is earmarking money for the new capability even as sequestration is forcing programs cuts, according to the service’s top acquisition official.
“We are heading towards the M-code capability,” said Heidi Shyu, assistant secretary for acquisition, logistics and technology. The Army has worked “our S&T (science and technology) pieces,” she said, noting that the Air Force was developing the necessary circuit cards through is Military GPS User Equipment (MGUE) program.

A confluence of technology, policy, and applications is turning indoor venues into the next big frontier for positioning and navigation.
Recent market studies have heralded the prospects for positioning, navigation, and tracking inside buildings where GNSS signals are often attenuated or blocked entirely. Many products and conceptual designs combine the indoor technologies with GNSS to provide “ubiquitous” positioning.

GPS pseudolite used in experiment at University of New South Wales Satellite Navigation and Positioning LabInternational aviation officials have asked U.S. experts to consider updating standards for GNSS aviation receivers to improve their ability to withstand interference from repeaters, pseudolites, and jammers.
Repeaters — generally used to extend navigation signals inside buildings where they would otherwise be blocked — rebroadcast GNSS satellite signals and therefore operate in the same frequency band. Although useful within a building, care must be taken to confined the repeater’s signal lest it confuse other receivers operating nearby.

Raytheon UK launched a new enhanced version of its battlefield GPS L1/L2 anti-jam (GPS-AJ) capability, Landshield, this week (October 13–15) at the annual conference of the Association of the U.S. Army (AUSA 2014) in Washington, D.C.
A multi-element antenna with the anti-jam processing in a single small “one-box” form factor that interfaces at the RF level, Landshield is designed to enable GPS equipment to function unimpaired against a full range of hostile jammer types including narrow band, broadband, continuous wave, pulse, swept, and spectrally matched.

My favorite bumper sticker this month: “Oh, no! Not another learning experience!”
After 20 years of putting together a European GNSS program, disappointment over the skewed launch of the first fully operational Galileo satellites is palpable and widely felt. For end users, it is uniformly bad news, and no system provider that sincerely wants to achieve interoperability and robustness in a system of GNSS systems can relish the European program’s current difficulties.
