COORDINATE METER Russian patent published in 2000 - IPC

FIELD: measuring equipment, applicable for location of moving objects. SUBSTANCE: the known coordinate meter, having two antennas, two receivers, analog-to-digital converter, coordinate computer, switchboard and indicator; the first and second antennas are connected to the inputs of the first and second receivers, respectively, the output of the analog-to-digital converter is connected to the input of the coordinate meter, features a low accuracy of determination of the object coordinates. Introduction in the known device of additional three analog-to-digital converters, two coordinate computers, three digital filters, two adders, two multipliers, subtracter, delay element, OR gate, subtracter of weight factors, track sensor, heading sensor and control panel enhanced the accuracy of determination of the object coordinates at an average by 16 times. EFFECT: optimized estimation of coordinates on the basis of ground, satellite and self-contained navigational systems. 2 dwg
