Humboldt-Tolyabe National Forest, Nevada USA
√ In the Pacific Northwest, in-car navigators often indicate “short cuts” through wilderness mountains—with tragic results. One victim survived 49 days before rescue in May. (Reports blamed GPS - not digital maps or wireless communication.) GPS.GOV straightens out misperceptions, for those who need a guardian angel, but just get a signal.

GPS data from the North-South Mandeyapecua thrust fault in Bolivia shows that it is under extreme pressure and the area could face an 8.9 quake, 125 times stronger than the expected magnitude, said a new study published in May’s Nature Geoscience. The 2010 Chile and 2011 Japan earthquakes inspired many experts to reassess risk.

√ After several delays, India’s GAGAN satellite (GPS-Aided-Geo-Augmented Navigation) will take off from Europe’s Spaceport on May 21 aboard an Ariane 5 rocket. India’s space organization ISRO and the Airport Authority of India need a successful launch to advance their safety-of-life qualified aircraft navigation system. GAGAN is Sanskrit for “sky.”

Space, the final frontier
DARPA’s Tactical Technology Office has $8 million in 2012 to work on an advanced space system project that sounds like a Big Brother to GPS. XTIM will use X-ray pulsars to calculate position and absolute time from celestial sources, broadcast the data to earth and space . . . and help GPS. (Update the constellation ephemeris! Detect jamming and spoofing attacks!)

√ The 8th Compass/Beidou-2 satellite, an IGSO, launched on April 10. It marked “a new stage of development,” according to the Beidou website. China intends to complete its regional system within two years, described as “independent, autonomous and compatible with the world’s GNSS interoperability” with short messaging and other China-specific services.

√ The giant Airbus "Beluga" cargo plane is the first to be EGNOS equipped, with certification flights beginning soon, says ESA. Pau Pyrénées Airport in southern France is the first to use EGNOS safety-of-life vertical guidance signal. The plan is to  to equip smaller airports with shorter runways next, with 100 complete by 2020.
