Analysis of Moving Radio Electronic Measuring Instruments Characteristics

The paper deals with the issues of increasing the measurement accuracy of measuring instruments located on a moving object. For measuring instruments located on moving objects the problem of increasing the measurement accuracy under the influence of factors is discussed: the parameters of the object's motion, interference, as well as methods of processing measurement information. The carried out theoretical study made it possible to obtain relations for the accuracy of moving object navigation coordinates. It has been found that the intensity and width of the spectrum of velocity fluctuations of a radio-electronic navigation coordinate meter have a significant effect on the accuracy of determining the moving object coordinates. It is shown that for a digital measuring device the gain in accuracy due to the use of optimal linear filtering depends on the discretization step.
