COMPLEX INERTIA-SATELLITE NAVIGATION SYSTEM Russian patent published in 1997 - IPC

FIELD: navigation equipment, design of complex navigation system including device of inertial navigation and gears of user of satellite navigation system. SUBSTANCE: system incorporates radio receiver connected via amplifier to antenna and linked with some outputs to computer of position of navigational satellites and with other outputs - to unit of initial setting of almanac of data on satellite orbits. Outputs of this computer are connected to inputs of unit of isolation of radio visible satellites. Outputs of this unit are connected to inputs of unit of isolation of working constellation of satellites connected with outputs to inputs of computer of position of user. Besides them system includes meter of projections of absolute angular velocity composed of three orthogonally installed laser gyros, meter of projections of apparent acceleration composed of three accelerometers mounted along corresponding axes of laser gyros. Mentioned meters are connected through correction units to computer of navigational parameters which outputs are coupled via third correction unit to output system and to outputs of display. Some outputs of system are connected to inputs of unit of isolation of radio visible satellites, some outputs of computer of navigational parameters are connected to first group of inputs of information authenticity analyzer, other group of inputs of it is connected to outputs of computer of position of user. Outputs of analyzer are connected through unit through unit of keys to inputs of navigational filter which first group of outputs is connected correspondingly to inputs of two correction units and which second group of outputs is coupled to inputs of third correction unit. EFFECT: enhanced functional efficiency and reliability. 4 dwg
