Synthesis of the moving object positioning system

Abstract

The choice of structure and parameters of the positioning system of a moving object based on a complementary filter using GPS-receiver and accelerometer is considered in order to reduce the effect of significant short-term interference of the GPS receiver when there is a zero offset accelerometer. For the analysis the complementary filter constructed according to the filtration scheme is accepted. Second- and third-order filters are compared. The high efficiency of the filter is shown. It is shown that by choosing a certain structure of a complementary third-order filter, it is possible to eliminate the steady-state component in the filter output signal.
