FIELD: information technologies.
SUBSTANCE: in method to create a set of extending codes for use in satellite navigation system comprising a constellation of satellites, an initial set of bit combinations is generated, where each bit combination reflects a possible extending code, and optimisation of the initial set of bit combinations is carried out, when at least some bit combinations in the initial set are changed or replaced in order to create a full set of bit combinations for use as a set of extending codes.
EFFECT: reduction of synchronisation time and accuracy of location detection.
