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 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.
With the continuing strains on the U.S. national budget and the possibility that the Administration’s sequestration program could last for several more years, Pentagon planners are said to be worrying that the costs of the future GPS III system could become out of reach, despite its major advances and the need to have modernized replacement satellites ready to be deployed as the orbital lives of current satellites end.
Lockheed Martin has chosen CMC Electronics to provide a new flight management system (FMS) and GPS landing sensor for the avionics upgrade package it is producing for the U.S. Navy’s C-130T fleet.
A change in FAA policy that allows the use of GPS approaches at alternate airports should be welcome news for pilots. “Operators are now permitted to file a flight plan for a GPS approach at either the destination or an alternate, but not both,” according to NBAA. The new policy took effect on April 4. Previously pilots could fly GPS approaches only at the destination airport.
Blue Sky Network unveiled the new HawkEye Portable Tracker (PT) Plus fleet management tool at Heli-Expo ’13, which offers more consistent, accurate and reliable connectivity throughout a customer’s multimodal network.
“We sell not just the hardware, but also software, service and airtime,” said Paul Duran, v-p of marketing and sales. “We have customers with fleets in the Gulf, in Canada–all around the world–so we’re growing to help manage our customers’ fleets, wherever they may be and whatever types of assets they may have: air, sea, or ground.”
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.
The certification for India’s GPS-Aided GEO Augmented Navigation (Gagan) project is presently being led by the Director General of Civil Aviation (DGCA) and, according to an official statement, is “expected to be operational in the summer of 2013.” However, an Airports Authority of India (AAI) official, speaking on condition of anonymity, h
The road to future communications, navigation and surveillance operations will not include any major technology upheavals in user requirements before 2020, according to projected roadmaps presented at ICAO’s Air Navigation Conference in Montreal recently. In fact, new technologies mentioned for each of the three regimes were usually described in terms of their potential future benefits, with no suggestion of their actual readiness for implementation.
