What this relates to:
Flight operations use GPS signals for navigation and positioning. The GPS receives signals from a satellite network in orbit around the Earth, enabling aircraft to determine their precise geographical position, height and speed. Frequency transmitters are used on the ground to block or jam these signals in the air for military purposes. GPS malfunctions primarily occur near geographical conflict zones, for example in Eastern Europe and the Middle East.
Example:
A passenger aircraft is flying over the Middle East. Suddenly, the GPS transmits an incorrect position. The crew decides to switch off the GPS and continue the flight with other radio navigation devices. Since critical systems are designed to be redundant, this has no negative consequences for the safe continuation of the flight. After ten minutes, the GPS signal reconnects and the aircraft resumes normal navigation.
