FIELD: radio engineering, communication.
SUBSTANCE: method of controlling reference frequency generator in a wireless device, which includes a wireless communication system and a satellite positioning system, involves selecting reference generator parameters which correspond to the least error of the reference frequency generator, wherein the selection is determined in the wireless device based on processing a first and a second frequency shift parameter, respectively determined based on a first wireless technology and a second wireless technology; increasing the certainty counter value contained in the wireless device which indicates certainty in the selected reference generator parameters, at least in part, in response to the selection of reference frequency generator parameters; detecting a satellite based on the selected reference frequency generator parameters; obtaining a location positioning using the satellite and determining its quality using the satellite and updating reference frequency generator parameters in response to determination of satisfactory quality of location positioning using the satellite.
EFFECT: shorter search and detection time.
