The Coalition to ‘Save Our GPS,’ through vice president and general counsel Jim Kirkland of founding member Trimble, has responded to claims by LightSquared, which is seeking approval for a terrestrial broadband communication service in a frequency spectrum very close to that of GPS.
Million Air Dallas completed the validation flight requirements to obtain authority to conduct RNP-AR (formally SAAAR) approaches in its Gulfstream G450. The Dallas FBO developed its own RNP-AR program without the help of any consultants, it added.
Can GPS and LightSquared coexist? Within the civil and military GPS community, the answer has been emphatically and unequivocally, “No.” Until last week, that is. Attendees at the annual convention of the U.S. Institute of Navigation held in Portland, Ore., had been confident that the laws of physics made coexistence of the two impossible.
Southwest Airlines’ ambitious fleetwide implementation of required navigation performance (RNP) operations is making slow progress. Since initiating flights in January using the precision approach procedures to save track miles and fuel, the airline’s use of RNP represents just 1 percent of its daily operations, said Capt. David Newton, Southwest senior manager of airspace.
To the puzzlement of the GPS community and independent radio propagation experts, the FCC ruled on September 13 that LightSquared should conduct further tests of its signal transmissions on its alternate, lower L-band frequency farther removed from the GPS frequency. Tests on a LightSquared frequency closer to GPS earlier this year produced extreme interference.
LightSquared signed an agreement yesterday with Javad GNSS to develop a system that it claims will eliminate related interference issues between LightSquared’s planned 4G broadband network transmitters and high-precision GPS devices.
The high-level industry and government committee tasked by the FAA with developing “a common understanding” of NextGen priorities has recommended a set of baseline airborne equipment and next will advise on operational or financial incentives that would help aircraft operators install that equipment.
Jeppesen’s Mobile FliteDeck went live on Apple’s AppStore on July 25 and had been downloaded more than 3,000 times before Jeppesen formally announced the iPad app’s release three days later. Mobile FliteDeck builds on Jeppesen’s Mobile TC, which displayed worldwide terminal charts on the iPad, with new functionality, including en route charts and geo-referenced (own-ship) position display on GPS-equipped iPads.
The former head of the New York State Police aviation unit has been charged with grand larceny for selling a state-owned Garmin 496 GPS to a fellow trooper. Retired Maj. Robert Kreppein is accused of selling the unit for $1,600 in 2008. Kreppein retired in July after media reports surfaced that he was being investigated for allegedly approving civilian flights on state police helicopters.
“The effects of LightSquared deployment would be far-reaching and potentially devastating to aviation,” the FAA wrote to the President’s Space-Based Positioning, Navigation and Timing (PNT) group in a report that was recently leaked to the media.
