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.
The GPS industry’s failure to comply with the Department of Defense’s receiver filtering standards is the root cause of potential interference issues involving LightSquared’s proposed broadband wireless network, the company has told the FCC.
Low-powered incoming GPS signals are allocated 1559-1610 MHz in the L-Band radio spectrum. The neighboring spectrum–from 1525-1559 Mhz–is allocated to other, equally low-powered, incoming satellite signals, such as Sky Terra’s. GPS receivers are open to signals above the blue line shown, but filter out signals below it, and require modification to accept Glonass.
Accord Technology’s NexNav mini GPS Waas Class Beta-1 sensor has been recognized by the FAA as meeting requirements outlined in Advisory Circular 20-165. The 20-165 requirements cover accuracy and other parameters that GPS sensors will need to meet standards for ADS-B operations. The FAA will require mandatory equipage with ADS-B out systems beginning in 2020.
LightSquared is running an advertising campaign in Washington, D.C., that includes prominent multiple advertisements along the platforms of downtown stations of the city’s Metro system serving Capitol Hill, FAA headquarters and other key government offices. Photo at left was taken this morning by an AIN staffer at L'Enfant Plaza Metro station.
With fresh evidence that LightSquared’s proposed wireless broadband network will cause widespread interference to GPS signal reception, principals of the industry Coalition to Save Our GPS went on the offensive today in a media conference call.
The ongoing controversy about whether LightSquared’s proposed network of 40,000 powerful ground-based stations transmitting high-speed Internet across the nation would interfere with adjacent GPS frequencies became more intense last month.
