By Inside GNSSA number of user conferences for customers of Hexagon AB’s precise measurement brands and products will be combined in the Swedish corporation’s first international conference this summer.
It will take place at Orlando World Center Marriott Resort in Orlando, Florida from June 6 through June 9, 2011.
The theme is "Building a Smarter World," and will include 200 technical and training sessions and an industry exhibition.
By Inside GNSSTrimble announced on March 16 that it has entered into a definitive agreement to acquire certain assets related to the OmniSTAR GNSS signal corrections business from Fugro N.V.
The acquisition is expected to significantly expand Trimble’s worldwide ability to provide correction services for a broad range of land-based applications in addition to OmniSTAR’s current focus in agriculture. Fugro’s offshore marine business is unaffected.
By Inside GNSSOn March 2, ESSP (the European Satellite Services Provider) declared the safety-of-life (SoL) signal from the European Geostationary Navigation Overlay Service (EGNOS) officially available for use by aviation, following European Commission (EC) authorization to provide the service.
Similar to the U.S. Federal Aviation (FAA) Administration’s Wide Area Augmentation System (WAAS), EGNOS transmits real-time corrections to GPS signals over a large expanse of Europe and north Africa.
By Inside GNSSThe International Committee on GNSS (ICG), is a voluntary United Nations–backed association that brings together GNSS and augmentation providers — including the United States, Russia, European Union, China, India, and Japan — and associate members representing key user communities.
By Inside GNSSThe GlobalGEO Fair will take place in the Monjuic Venue, Hall 6 at Fira de Barcelona exhibition center in Barcelona, Spain from March 15 to March 17.
The fair features the latest products for GPS navigation, 3D mapping, geographic information systems, photogrammetry, teledetection, geodesics, topography, satellite navigation, intelligent transport systems and communications.
By Inside GNSSRelease of a British Royal Academy of Engineering (RAE) report today (March 8, 2011) adds another chapter to the growing chronicle of GNSS vulnerability — concluding that the integrity of GNSS is insufficient for safety-of-life applications.
By Inside GNSSSpectracom has announced its new 16-channel GPS constellation simulator, the Pendulum GSG-55.
The latest in the Pendulum line of GPS receiver test instruments, the GSG-55 is able to simulate Satellite-Based Augmentation Systems (SBAS), such as the U.S. Wide Area Augmentation System and the European Geostationary Navigation Overlay Service (EGNOS).
By Inside GNSSSpirent Communications’ Positioning Technology Division, Paignton, UK, has announced that the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent’s GSS8000 Multi-GNSS Constellation Simulator to support further development of the Quazi-Zenith Satellite System (QZSS) program.
Responsible for the development of the initial QZSS user equipment, JAXA is using the GSS8000 to verify QZSS receiver performance.
By Inside GNSSA European Commission (EC) communication sent to the European Parliament and European Council today (January 18, 2011) estimates that completing a fully operational capability (FOC), 30-satellite Galileo system and the European Geostationary Navigation Overlay Service (EGNOS) will cost an additional €1.9 billion above the €3.4 billion already allocated.

In satellite navigation, a GNSS receiver must account for several sources of error such as relativistic effects, atmospheric propagation delay, offset of satellite clocks from system time and satellite ephemeris. In order to accurately compute user position, velocity, and time (PVT), these errors need to be predicted/estimated precisely.
By Inside GNSSGMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.
As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.
