SYSTEM, METHOD AND USER'S TERMINAL IN SYSTEM OF UNAMBIGUOUS DETERMINATION OF LOCATION WITH THE USE OF TWO SATELLITES ON LO- ALTITUDE NEAR-EARTH ORBIT

摘要

FIELD: location of objects, in particular, user's terminals, with employment of means of satellite communication system.;SUBSTANCE: the offered system has a mobile telephone set, interline integration unit, at least two satellites with known orbits, means for determination of such parameters as the distance from the user's terminals to each of the satellites and their difference. Provision is also made for means (one or both) for determination of such parameters as the radial velocity of one of the satellites relative to the user's terminal and the difference between the radial velocities of one and the other satellite relative to the user's terminals. The means for location of the user terminal in the interline integration unit is engageable with the above means. It acts on the basis of the known positions and velocities (orbits) of the satellites and the above parameters: distances of satellites from the user's terminals, radial velocities and the their differences. Estimations of the positions of the satellites are specified on the basis of processing of the results of measurements of the given parameters.;EFFECT: provided unambiguous location of the user's terminal with a high speed of response.;28 cl, 13 dwg
