NovAtel Inc., has announced an agreement with the Indian Space Research Organisation (ISRO) to supply reference receiver products for use in the Indian Regional Navigation Satellite System (IRNSS) ground segment.
India-based Elcome Technologies Pvt. Limited, a sister company to NovAtel in the Hexagon Group of Companies, will provide local integration, training and technical support services for the NovAtel receivers.

Applanix Corporation announced that today (November 12, 2013) that the Trimble CenterPoint RTX correction service will be available across its entire airborne mapping portfolio.
Trimble CenterPoint RTX correction service is a GPS-, GLONASS-, and QZSS-enabled correction service built on Trimble RTX technology that provides high-accuracy GNSS positioning without the use of traditional reference station-based differential RTK infrastructure.

U.S. aviation officials on Monday (December 30, 2013) named the winners of a high-stakes contest to operate one of six new research and test sites for unmanned aircraft. The Federal Aviation Administration (FAA) will now work to help the sites set up safe operations and create the structures needed within the agency to help it use the sites’ research results.

The U.S. Department of Transportation (DoT) is asking the Air Force to cancel its plan to add navigation data to two key civil GPS signals this year, saying they are concerned that the approach and “nonstandard engineering tools” military officials plan to use could put GPS users at risk.

At a news media conference in Beijing on the first anniversary of the BeiDou Navigation Satellite System (BDS) declaration of full operational capability (FOC) for its regional service, officials reported on the current performance of China’s GNSS system.
The BDS program also released two new technical documents, including an updated interface control document (ICD) that describes the second civil signal, B2I, and a “BDS Open Service Performance Standard (version 1.0).”

How many times, as some once-promising politician stumbles up against his pull date, have we heard that irreverent anthem of The Who invoked?
Thousands? Millions?
Yes, back in the wreckage of the second George Bush’s second term, Barack Obama looked pretty good by comparison. Even then, though, raising the banner of “Hope” before the eyes of a desperate nation was a risky thing to do.

A common refrain in the world of GNSS is the desire for “interoperability,” the use of signals from multiple systems without a decline — and potentially even an improvement — in the quality of results.
Achieving this depends on large part in establishing comparable parameters — particularly the geodetic references and timing systems — among the GNSSs along with a dense network of ground reference stations that can provide continuous, precise monitoring of satellites’ orbital positions.

Ionospheric scintillations are rapid temporal fluctuations in both amplitude and phase of trans-ionospheric GNSS signals caused by the scattering of irregularities in the distribution of electrons encountered along the radio propagation path. The occurrence of scintillation has large day-to-day variability. The most severe scintillations are observed near the poles (at auroral latitudes) and near the equator (within ± 20 degrees of geomagnetic equator).

Trying to revive a years-dead federal program is usually the kind of hopeless task that even Sisyphus wouldn’t touch.
But determined supporters of eLoran are gaining ground in their effort to resurrect the cancelled radio-navigation network and, propelled by new worries over GPS jamming, they appear poised push the issue through.
