The intensive development of space technologies used in military applications has brought a huge number of applications in the economy. First of all, satellite navigation systems should be distinguished. All systems in operation today are based on signals from satellites located at relatively high altitudes above the Earth. The hegemonic aspirations of some groups that rule in space "powers" provoke states, eager for their own peaceful development, to protect themselves from destructive activities in outer space. An example of such a destructive action in space are attempts to physically destroy inactive satellites, causing the formation of a huge cloud of debris in space from the crashed satellite, threatening the safety of all other space objects passing through it. There are currently known successful attempts to destroy LEO (Low Earth Orbit) satellites orbiting at lower altitudes. The more difficult task is to destroy the GEO satellites - orbiting at much greater heights above the Earth. The satellites of Medium Earth Orbit (MEO) navigation systems are also relatively large distances from the Earth's surface (about 20,000 km), but targeting them is facilitated by the fact that they transmit precise positions in their signal. Providing a potential enemy wishing to destroy these satellites with accurate information about their own location is unacceptable in the event of such a threat. You can turn off beacons, but then all civilian users will no longer be able to use this service. The paper presents the way of functioning of satellite navigation, in which the coordinates of satellites are intentionally distorted, transmitted in the satellite message while continuing relatively accurate positioning.
