The Real-Time Phasemetric Microwave Navigation System for Position Detection and Drive Control of High-Speed Objects

The concept of construction of navigation system for high-speed ground transport on the base of a phase metric method is grounded. It is shown, that the system provides high accuracy of position fixing of high-speed objects (of the order of one-two decimeters at speeds of moving up to 500 km/h and own linear dimensions about 100 m), sufficient for control of the linear engine and also allows to process the information going from measuring sensors and to give out control commands on executive units in a real time mode. The requirements to stability of frequency of basic and mobile microwaves-generators are determined. The offered built-in subsystem of diagnostic of working state of radio-navigation system promotes higher reliability of control system of high-speed transport mean and so higher safety of the all high-speed transportations.
