It’s been three months since Sikorsky announced that its S-92 rig approach system has gone into operation in the Gulf of Mexico with oil and gas transport provider PHI, and here at the show, the airframer is providing demonstrations of the safety enhancement.

NobileSoft, a software company created by a helicopter pilot, has joined forces with independent research company Sintef to bring to market a new GPS-based powerline warning system for low-flying aircraft. Collisions often occur when aircraft fly at low levels on power- or pipeline patrols.

GPS Source, a manufacturer of indoor GPS receivers, released its GLI-Metro-G system, which provides a variety of GPS signal types and control over effective radiated power (ERP) levels. GLI-Metro-G can receive GPS L1/L2 and Glonass L1/L2 signals, and users can select both GPS and Glonass or each type individually. An antenna must be mounted on the outside of the building to pass the signals through to the receiver. GLI-Metro-G will also accept Galileo signals when that system becomes operative, as well as those from other future GPS-type systems.

Several satellites in Europe’s satnav constellation, Galileo, are already in place, with the full complement of 30 set for launch by 2019.

After several years of anticipation, the planned earth-girdling network of five global navigation satellite system (GNSS) constellations is taking tangible form in space. Two of them–America’s GPS and Russia’s Glonass–are already fully operational. Glonass reached that goal in 2009, joining the pioneering GPS, which achieved that status in the 1980s.

The Aeronautical Information Manual’s (AIM) Change Two takes effect on March 7 and includes a number of updates. One describes the requirements for two independent navigation systems. It also clarifies the application of different technical standard orders and updates the guidance for standalone GPS approaches. The update adds guidance for using “T-Routes” and “Q-Routes,” as well as the ground based augmentation system (Gbas).

An Airports Authority of India official, speaking on condition of anonymity, told AIN the schedule for that nation’s new GPS-augmented navigation system (Gagan) might be pushed back to the end of this year. The Gagan system is the only satellite-based augmentation system that has an enhanced algorithm specifically for the equatorial region.

Russia plans to announce this month that its civil aviation fleet will be required to carry Glonass, that nation’s GNSS, or combined Glonass/GPS units, but not GPS on its own. The mandate will be unveiled at this month’s triennial ICAO Air Navigation Conference, and it has significant cost implications for western-built corporate aircraft on the Russian register, all or most of which likely carry just GPS. Foreign-registered aircraft flying in Russian airspace would be exempt from the rule.

So, first, who needs three more worldwide satnav systems, when we already have GPS? Why do these others want to spend billions just to keep up with the U.S.? There are two reasons: one political and the other practical. Politically, GPS has become a (not the) dominant technology in almost every part of human life around the world, in government, national security, industry and private life, with more than a billion receivers being used daily for thousands of applications, from simple to critical.

In its latest surprise move, would-be broadband provider LightSquared has morphed from a Chapter 11 bankruptcy case, with just a few months to find some closure with its creditors, to having an arrangement with them to allow it to continue in business and spend up to $190 million to fund its operations until September next year.
