FIELD: radio navigation.
SUBSTANCE: invention relates to the field of radio navigation and may be used to determine the location of air, ground, surface mobile objects. The method for multi-position near-range radio navigation includes the formation of a radio navigation field by synchronous emission of broadband periodic radio signals with a given rangefinder code from radio navigation points spatially spaced on the Earth's surface with known coordinates, reception of radio signals using an on-board navigation receiver of a mobile object, separation of received signals according to a given rangefinder code, measurement of the moments of their arrival and the corresponding pseudo-distances to radio navigation points, measurement of heights with the help of an on-board meter, determination of the location of a mobile object by measured pseudo-distances and height. In this case, the radiation and reception of radio signals are carried out using omnidirectional antennas in the horizontal plane at a constant radiation power, the amplitude of the received radio signals is additionally measured, and the location of the mobile object is determined taking into account the measured amplitudes and their dependence on the distance to the radiation site.
EFFECT: increasing the accuracy of determining the location of the mobile object.
