- processing of the measuring signals by averaging;

- determining the size differential correction to satellite measurements of navigation signals in real time;

- transfer the values of differential correction;

- post-processing of the measured signals;

- archiving of the measured signals in the block 13 archiving data.

Unit 3 measuring geometrical parameters of the path contains a sensor of the traversed path, designed to determine the magnitude and direction of trolley movement 1, forming clock pulses for operating the control system 2 in increments of, for example, 0.125 m coordinate of the path of the pendulum level sensor for level measurement of rail lines and the linear displacement sensor for measuring track gauge.

The control and computing system 2 is made in the form of hardware and software devices, which in real-time captures the geometric measurement of parameter the path and positioning signals potenzmitteln truck 1, considering the magnitude of differential correction clarifies the values of signals positioning potenzmitteln truck 1, detects deviations of the actual path settings from the design values, and performs the "binding" measurement of geometrical parameters of the path of the adjusted coordinates of the path.

Network center 10 is connected with the transceiver unit 7 placed on potenzmitteln cart 1, and the external system 17 warning track teams channel of mobile communication, such as GSM channel. In this case, the transmitting unit 7 is designed as a GSM modem.

The receiver 4 of the navigation signals emit signals of GLONASS / GPS measurement information to indicate coordinates of the truck 1.
