Satellite navigation systems

Garmin released software updates yesterday for GLO, a remote GPS/Glonass sensor for iOS and Android smartphones and tablets, that adds new capabilities. Originally, GLO could provide accurate GPS data to one device via Bluetooth. With the latest software update, GLO can connect via Bluetooth with up to four devices simultaneously. A few changes have also been made to the functionality of the power button, which will now reduce the likelihood of GLO inadvertently turning on when stored in a flight bag.

Flight-testing at Toulouse, France, and Frankfurt, Germany, has proved that a reliable alternative to an ILS signal can be produced with a GNSS constellation and single-frequency input signal. Eurocontrol’s Sesar air traffic management research team worked with equipment manufacturers Thales, Indra-Navia, Honeywell and Thales Avionics using a ground-based augmentation system (GBAS). Further testing at both airports is expected to resume in the middle of next year.

When representatives from every world nation and every civil aviation organization gather at the triennial ICAO Assembly, topics on the agenda include current progress and issues as well as future challenges and potential solutions.

Any of the 6,000 helicopters that annually use the helipad at Eurocopter’s facility in Donauwörth, Germany, will now find arrivals easier in poor weather with the recent certification of a GPS localizer performance with vertical guidance (LPV) approach to the pad, one of the few in Europe certified for all-weather operations.

In 2008 Donauwörth became the first European helipad to introduce satellite-based Rnav (area navigation) specifically for use by rotorcraft.

Eurocopter obtained the first license in Europe permitting localizer-performance with vertical guidance (LPV) approaches on a helipad, at its development and production facility in Donauwörth, Germany. The helicopter manufacturer emphasized that such a procedure improves safety in poor visibility, since aircraft can overfly obstacles more safely.

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.

Harbinger Capital Partners and other entities associated with the LightSquared high-speed wireless Internet access system have filed a lawsuit against Deere & Company, Garmin International, Trimble Navigation, The U.S. GPS Industry Council and The Coalition to Save Our GPS.

After only four years in Brazil, Blue Sky Network, which offers satellite tracking of and communication with vehicles operating in the air, on land and at sea, has built up a sizable client base, including the Líder fleet that serves Petrobras, the Helisul air taxi operator and energy exploration company HRT. Here at LABACE show-goers can see how Blue Sky’s New SkyRouter and other systems work at the company’s display in the exhibition hangar (Stand 5020).

Harbinger Capital Partners and other entities associated with the failed LightSquared 4G broadband network filed a lawsuit against Deere & Co., Garmin, Trimble Navigation, The U.S. GPS Industry Council and The Coalition to Save Our GPS. The lawsuit claims that the defendants failed to disclose information about GPS interference problems caused by an adjacent frequency spectrum that LightSquared was allocated to use and seeks $1.9 billion in damages.

South Korea plans to provide radio navigation coverage with five stations–two legacy loran-C stations (in Pohang and Kwangju) and three yet-to-be built eLoran stations.

South Korea has been subject to annual GPS jamming attacks by its North Korean neighbor since 2010. Over that period, jamming has extended over longer periods, with the longest being a continuous 16-day attack, employing various frequencies, techniques and signal strengths. As the jamming periods increased each year, they affected more and more GPS users. Last year, South Korean officials estimated that 1,016 aircraft lost GPS signals, as did 254 ships and a large number of cellphone towers.
