FIELD: radio engineering, possible use for finding location of user of mobile communication device.
SUBSTANCE: in accordance to the invention, generation of such an estimation algorithm based on a priori information is suggested, which provides optimal solution in average for whole service area of navigation system, where client equipment acts as the source of navigation signal. Location of client is determining on basis of measurements of delays and levels of user signal by several base stations.
EFFECT: increased precision when determining location of clients inside rooms due to additional usage of a priori information about possible location of client and probability of his presence in various areas within area of service of navigation system.
