One of the world's largest manufacturers of aircraft, military and space equipment, Boeing Corp., announced that it has patented a new development, the essence of which is to protect the GPS receivers with the help of a blockade from unauthorized interference.
The accompanying note to the patent, published on the website of the US Patent and Trademark Office, says that the development is an on-board system for backup and protection against spoofing.
GPS spoofing allows you to "confuse" the transmitter by sending false signals to it. It is used to confuse sensors, distorting the location data of certain objects whose coordinates were initially set correctly.
"The backup will store reliable information received from GPS, so the system will be fault-tolerant and will be used on all types of vehicles, including unmanned vehicles," the explanatory note to the patent says.
Thus, using the technology of blocking to protect on-board systems, Boeing expects to secure its equipment from false signals. If necessary, the backup copy of the data will be re-deployed if the security system detects attempts to change coordinates.
