FIELD: radiolocation.
SUBSTANCE: method can be used in cellular communication systems for finding location of mobile station. Maximal precision of location is achieved at minimal total energy of signals transmitted during location procedure. Correction of errors is provided which errors relate to absence of signal propagation direct beam. Decision of location completeness is made upon forming estimation of coordinates of mobile station. For the purpose the data is used which are available at any base station immediately after reception of location signal as well as estimations of coordinates formed later. Moreover, step of correction of measured times of arrival of location signal is introduced to correct errors. Correction is based upon detecting of absence of propagation direct beam and on subtracting value of compensation being proportional to average radius r of area of objects of dissipation close to mobile station.
EFFECT: increased precision.
