Two companies angling to provide the government with cutting-edge, GPS-based weather data may get a boost this fall if a bill aiming to improve forecasting wins U.S. House approval.
The companies, Bethesda, Md.-based Planet IQ and GeoOptics, Inc., of Pasadena, California, hope to use GPS radio occultation or GPS-OR to provide the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense with weather data.

In a part of the world where frustrated drivers will park anywhere, including squarely on a sidewalk, a local newspaper is using location data to shame car owners into shaping up.
The Village, a Russian online publication serving Moscow, St. Petersburg and Kiev; created a free app that notes a badly parked vehicle’s make, color, and license plate information when users snap its picture.

Doctoral-level graduate students and early-career engineers, researchers and instructors from Japan and the rest of the world will meet at a weeklong summer seminar this August in Tokyo, sponsored by the Institute of Positioning, Navigation and Timing of Japan.
The summer school will take place in from August 19 through August 24 at the Tokyo University of Marine Science and Technology (TUMSAT). Classes wil be held in English.
Trimble has introduced its next-generation unmanned aircraft system (UAS) — the UX5 aerial imaging rover with the Trimble Access aerial imaging application.
According to the Sunnyvale, California– based company, the new UAS enhances the image quality and workflows its predecessor, the Trimble Gatewing X100. Combined with the Trimble Business Center photogrammetry office software module, the Trimble UX5 is provides a UAS photogrammetric mapping solution specifically designed for surveyors and geospatial professionals.
Prof. Jingnan Liu, Chinese Academy of EngineeringSince announcing plans in late 2006 to build its own GNSS system — BeiDou-2 (BDS), China proceeded quickly to establish a fully operational regional system late last year with a clear plan to complete a global system by 2020.
Beginning with its first launch in April 2007, BDS has put 16 satellites in orbit, some in dual launches, with 14 BeiDou space vehicles currently transmitting healthy signals: 5 in geostationary orbits (GEO), 5 in inclined geosynchronous orbits (IGSO), and 4 middle Earth orbit (MEO) spacecraft.

Paul Flament, Head, European Commission Satellite Navigation Unit. Photo by Peter GutierrezPaul Flament is head of the European Commission’s Satellite Navigation Unit. His primary job, essentially, is to manage the Galileo program of the European Union (EU). With four operational satellites now in orbit and an ambitious schedule to set in place a constellation of 26 by 2015, Flament sat down with Inside GNSS to talk about a number of pressing issues that could affect the future of Galileo.
Flament first addressed the EU GNSS Regulation, the much-anticipated document that sets out just who will do what in the future Galileo program.
