aircraft and helicopter sighting navigational systems. SUBSTANCE: navigator includes power supply unit, antenna unit and receiver-meter of satellite navigational systems connected by two-way communication, controller and storage module also connected by two-way communication, micro-computer, radiomodem connected in series by integration module and indicator, interface module, temperature control unit connected with input and output of power supply unit, common bus connected with radiomodem ports by two-way communication, integration module, interface module, micro-computer and controller. Second and third ports of receiver-meter of satellite navigational systems are connected by two-way communication with second port of integration module and second port of radiomodem respectively; second input of indicator is connected with signal output of receiver-meter of satellite navigational systems; third port of radiomodem is connected by two-way communication with third port of integration module and outputs of power supply source are connected with common bus. Radiomodem is two-directional; storage module employs flush-storage and common bus is made according to ISA standard. EFFECT: extended functional capabilities of navigator and field of its application with no change in its mass and dimensional characteristics. 4 cl, 1 dwg
