The Department of Defense is conducting GPS tests through Feb. 11 and Feb. 15- 22. The tests might make GPS signals unreliable or unavailable from 7-9:45 p.m. , an FAA advisory said. It will affect Georgia, Florida, South Carolina and North Carolina and parts of Alabama, Tennessee and Virginia.
Autos and boats will not be affected by testing, FAA spokeswoman Kathleen Bergen said.
Pilots should check notices to airmen, or NOTAMS, for updates and report any GPS anomalies to air traffic control centers
