US military training can block GPS systems for aircraft flying to the southeast and over the Caribbean
US military training can block GPS systems throughout the month for aircraft flying to the southeast and over the Caribbean, the FAA warns
- US Navy carries out training tests that can disrupt GPS systems in aircraft
- Aircraft flying to the southeast and over the Caribbean are in the risk zone
- If life-threatening problems occur, officials will give a “stop buzzer” for the test
An American military training exercise would allow many pilots without GPS to fly across the southeast and the Caribbean.
The ‘Carrier Strike Group 4’ exercise by the Navy is expected to disturb signals and other navigation systems from January 16 and run until January 24.
Aircraft flying from just 50 feet above the ground to around 40,000 feet are at risk, according to the Federal Aviation Administration (FAA).
In a statement, the Ministry of Homeland Security explains that the federal government is “obliged to perform GPS tests, training activities and exercises that interfere with GPS receivers.”

“Due to the fact that these training and testing activities can include a number of aircraft, ships and / or other military equipment and up to hundreds of personnel, cancellation or delay of a coordinated test should only take place under compelling circumstances,” the document continues.
“In general, only problems with life safety / flight safety justify cancellation or delay of an approved, coordinated GPS test.”
The government agency noted that in the event of a life-threatening event, the FAA will issue a “stop buzzer” for the test until it has considered the issue resolved.

As the report noted, the government regularly provides this type of training.
In 2018, the Air Force launched a massive combat exercise in which the FAA again warned pilots of GPS interference in the US.
“From tomorrow, January 26 and up to and including February 18, GPS-equipped aircraft operating in the Western United States must be prepared for potential interference with satellite signals at different heights,” Flying.com wrote in a bulletin.
“Training maneuvers will affect large parts of the Western US, including California, Nevada, Oregon, Wyoming, Arizona, Utah, Colorado, Montana, and New Mexico.”
Although little is known about the GPS jamming technology used during the exercise, according to The Warzone, working in the air is much higher than the ground, meaning that the impact on cars and GPS on the surface can be minimized to be.
Although the US Army blocks GPS systems, they also develop technology that blocks the problem.
In June 2019, the military agency appeared to have designed a variant that is resistant to GPS interference, or technology that tries to disable GPS by sending out fake signals or throwing each other at each other.
Without those GPS systems, US military officials and others around the world fear that their operations, such as moving troops or missiles, would come to a halt.
HOW DOES GPS WORK?
The Global Positioning System (GPS) is a network of around 30 satellites orbiting the Earth at an altitude of 20,000 km (12,000 miles).
The system can determine your location anywhere on earth.
The system was originally developed by the US government for military navigation, but now anyone with a GPS device, whether it is a navigation system, mobile phone or portable GPS unit, can receive the radio signals that the satellites broadcast.
Wherever you are on the planet, at least four GPS satellites are “visible” at any time.

Each channel sends information about its position and current time at regular intervals.
These signals, traveling at the speed of light, are intercepted by your GPS receiver, which calculates how far each satellite is based on how long it took for the messages to arrive.
Once it has information about how far away at least three satellites are, your GPS receiver can determine your location using a process called trilateration.
trilateration is an advanced version of triangulation, although it does not use the measurement of angles in its calculations.
Data from a single satellite give a general location of a point within a large circular area on the Earth’s surface.
GPS satellites have atomic clocks on board to keep the time accurate. However, general and special theory of relativity predict that differences will appear between these clocks and an identical clock on Earth.
General theory of relativity predicts that time seems to run slower under stronger gravity – the clocks aboard the satellites therefore seem to run faster than a clock on Earth.
