FIELD: measurement equipment.
SUBSTANCE: system generates integrated navigation data based on information from satellite navigation system and inertial navigation system. Integration of the information is implemented by means of a computer in compliance with Kalman filter algorithm. Information for the computer is shaped considering its reliability determined with the unit for automatic determination of reliability of satellite navigation information and changed by varying its weight coefficients. Integral data values for the computer considering weight coefficients and their variations are shaped by two multipliers, an adder and an integrator; initial values of weight coefficients are set from the control panel; data transfer is organised with the data transfer system and the commutator during the system operation process.
EFFECT: higher accuracy.
