METHOD OF DETERMINATION OF COORDINATES OF MOBILE OBJECT AND DEVICE FOR ITS REALIZATION Russian patent published in 1995 - IPC

FIELD: geodetic instrumentation engineering. SUBSTANCE: coordinates of mobile object are found by processing of radio signals from it at least three base-line stations and at additional reference station located at point with known coordinates. Device for realization of method has signal transmitter on mobile object with former of modulating radio signal. Each of base-line stations has radio receiving part, measurement channel, code channel, control unit, digital processing unit, signal transmission unit. It also includes reference station and central station, the latter being provided with multichannel input with number of channels corresponding to number of base- line stations. EFFECT: enhanced accuracy of determination of coordinates. 2 cl, 6 dwg
