Thus, the proposed device meets the criterion of "novelty."

The comparison of the proposed solutions with other technical solutions shows that the input elements are widely known. However, their introduction in the specified communication among themselves and with other circuit elements in the inventive device for radionavigation determination of the coordinates and velocity components of a moving object, these elements exhibit new properties, consisting in taking into account the correlation of the random components of the estimated object coordinates and temporary amendments to its on-Board time scale arising from the adverse effect of the geometric factor, as well as the filtering of the random component estimates the temporary amendments to the onboard time scale of the object using the results of the filtering random components estimates of the rate of change of the temporary amendments to the side the timeline object.

Really appreciate the gain in precision of the claimed device in comparison with the known as the ratio of marginal errors of estimates (accuracy 0,997), for example, for the x coordinate of the object:

where δml- the "residual" (when using differential mode, navigation and time definitions) systematic measurement error ranges from consumer to NSV (or from CCF to NSV);

σd- standard deviation (RMS) random component of measurement error ranges;

rxdthe correlation coefficient of the random component estimates CCW is dinate x object and the temporary amendments to the onboard time scale of the object;

N is the number of averaged estimated time correction and speed of change;

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.

FIELD: navigation.

SUBSTANCE: method can be used for designing of control system for rockets and radio altimeter for getting information on relative altitude of flight of rocket without irradiating radio signals at low and high frequencies and at irradiating of low energy at extremely low altitude flights. Before flight airplane-carrier of "air-surface" class rockets is placed into position with well known coordinates. Airplane-carrier is equipped with consumer navigation instrumentation which receives radio signals of GLONASS or GPS either both systems. Coordinates of position of aerial of consumer navigation instrumentation are calculated on the base of radio signals. Differential corrections if coordinates of airplane-carrier on the base of known real coordinates airplane-carrier. Values of differential corrections are introduced into consumer navigation instrumentation placed onto rocket before taking off. During flight of consumer navigation instrumentation rocket the plane coordinates of rocket and absolute altitude of flight of rocket are determined when taking differential corrections into account. Plane coordinates of rocket achieved during flight are introduced into digital map of region and height of region above which the rocket moves instantly is determined from plane coordinates. Relative altitude of flight is calculated and radio altimeter is switched on if relative altitude drops lower than calculated altitude of safe flight.
