FIELD: radio engineering, communication.
SUBSTANCE: signal is detected using receiving devices such as wireless position finding devices which search for signals from any source, for example, satellite moving objects and base stations. Data can be acquired from previously detected data based on estimation of changes in parameters, such as time and location, which can compromise reliability. In some cases data can be corrected by changes in parameters. Corrected data can be calculated by a receiving device using incomplete measurements of sets of signals, especially if data for assisting detection provided by a remote object include more differing parameters than those usually provided. The new data do not necessarily have to be obtained until reliability of previous data falls as a result of constraints on time extrapolation using Doppler coefficients if there is no detection of movement of a mobile station which cannot be corrected, which compromises reliability of previous data.
EFFECT: high reliability of detected data.
