VEHICLE POSITIONING DEVICE Russian patent published in 2019 - IPC G01C21/26 

FIELD: navigation.

SUBSTANCE: invention relates to navigation devices and can be used to locate vehicles moving along known trajectories. Device for positioning vehicles comprises a meter of three orthogonal projections of vehicle speed, the output of which is connected to the input of a speed module computer connected to the input of the integrator, computing unit made in form of two interconnected microprocessors connected to memory unit, input of first microprocessor is connected to integrator output, and its additional output is connected to control input of memory unit, outputs of microprocessors are outputs of device, on which values of latitude and longitude of vehicle are formed respectively.

EFFECT: technical result of the invention consists in reduction of hardware and computational costs when determining current coordinates of vehicles moving along known trajectories, as well as high accuracy of positioning.
