FIELD: physics.
SUBSTANCE: methods are based on the fact that in a local area of space, consumers who determine their location along the working constellation of the navigation system will have the same errors associated with the movement of satellites and the propagation of radio signals. In other words, at each instant they will have approximately the same corrective amendments due to the inaccuracy of satellite orbits and the condition for the propagation of radio signals. Compensation of these amendments will increase the accuracy of determining the location of consumers, leaving only individual errors for each device, in particular, multipath in the propagation of radio signals and internal receiver noise.
EFFECT: increasing the accuracy of determining the coordinates of single-frequency navigation receivers built into user mobile devices and not having the technical capabilities to obtain and apply corrective amendments from various existing differential subsystems.
