The Analogue Of GPS Based On The Interception Of Satellite Signals 

American engineers have shown that Starlink Internet satellite signals can be used for geolocation using amateur radio equipment.  Recording the signals of six flying satellites, they calculated the position in space with an error of 33.5 meters, and when using an altimeter and positioning on a plane, the error decreased to 7.7 meters. The article was published in IEEE Transactions on Aerospace and Electronic Systems and is also available on the website of the University of California, Irvine.

Starlink satellites emit a signal containing data for ground receivers. Using a compact receiver of their own design, Cassas and his team were able to capture these electromagnetic waves without deciphering the signal. They studied the general shape of the signal and were able to use it to determine the distance to the satellite. Scientists report that the use of Starlink satellites allows you to determine the location of objects on earth with an accuracy of 7-8 meters. Cassas and his team expect accuracy to improve as the Starlink constellation grows. SpaceX is not involved in this study and does not comment on it in any way. It is not yet clear whether the company will try to block the scientists’ research.
