New technology tests raise concerns for GPS users
May 17, 2011, 01:06 pm
The Federal Aviation Administration is advising pilots who plan on flying in Nevada this May to check their flight plans before takeoff. Lightsquared, a broadband wholesaler, will be testing its new wireless internet technology and the testing may disrupt Global Positioning System services in a 330-nautical mile circle in Nevada, according to AVweb.com.
"Pilots are advised to check NOTAMs (notices to airmen) frequently for possible changes prior to operations in the area," the FAA notice states. "NOTAMs will be published at least 24 hours in advance of any GPS tests."
Lightsquared is testing a wireless broadband system to see if its technology overlaps with GPS frequencies. The system is designed to work in a frequency band that neighbors the GPS frequency, but it is yet unknown whether the two will overlap.
Pilots should avoid flying in the testing range for the duration of May. Even if they have pilot life insurance, it can be very dangerous to fly without a GPS system.
The Coalition to Save Our GPS, an organization formed to protect the reliability and viability of GPS, is fighting for the Federal Communications Commission to protect GPS systems.
