If you rely on GPS heavily for things like work, research, or school, then you might want to take note that over the course of the next couple of weeks, the US Air Force will be conducting combat tests in the western US which will involve the jamming of GPS, resulting in GPS being disrupted temporarily.
According to a report from Flying.com, “The NBAA Command Center reports the U.S. military will begin training exercises on the Nevada Test and Training Range between 0400Z until 0700Z daily. Training maneuvers will impact vast portions of the Western U.S. including California, Nevada, Oregon, Wyoming, Arizona, Utah, Colorado, Montana and New Mexico. FAA enroute ATC centers affected include Albuquerque (ZAB), Denver (ZDV), Los Angeles (ZLA), Salt Lake (ZLC), Oakland (ZOA) and Seattle (ZSE).”
The idea behind the GPS jamming is meant to simulate combat situations where the USAF might encounter situations where their GPS no longer works. As The Drive points out, countries such as Russia are incorporating tactics that involve GPS spoofing and jamming which could severely impact the effectiveness during combat, which is why this training is taking place to prepare pilots for such situations and how to deal with them.
