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.
Avidyne signaled that it is joining the trend toward avionics with touchscreen controls by launching its IFD540 FMS/GPS/navcom system at EAA Airventure in Oshkosh, Wis., yesterday.
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.
Following extensive reports of GPS interference, LightSquared announced last week that it would vacate its L-Band frequency adjacent to GPS and move to one further away to greatly reduce, but not eliminate, interference with satnav signals.
A study released by the Save Our GPS Coalition warns of “serious repercussions for the U.S. economy” if LightSquared is allowed to broadcast 4G broadband signals that cause interference with GPS. According to the study, more than 3.3 million U.S.
West Star Aviation recently installed the first Rockwell Collins Pro Line 4 to Pro Line 21 upgrade on the Falcon 2000. The upgrade is now available for Pro Line 4-equipped Falcon 2000/2000EXs.
It is only in the past few of years that GPS approaches, pioneered in Alaska in the 1990s, have started to become available. These form another element of a future, efficient system where aircraft are managed in time as well as space, take efficient paths and don’t waste burning fuel in unnecessary holds.
Since early reports indicate that LightSquared’s transmitters do, in fact, interfere with GPS signals, LightSquared yesterday announced that it would vacate the frequency that caused major GPS interference and move to one farther away, where tests had shown minimum interference. However, some GPS receivers would still be affected by the company’s 4G signals even in this frequency band.
The controversy over potential interference to GPS from LightSquared’s planned nationwide network of powerful 4G broadband retransmitting stations has now drawn Congress into the dispute. Letters expressing concern about adverse effects of the LightSquared network on GPS have been sent to the FCC by House and Senate members.
