(EN) A NAVIGATION SYSTEM
(FR) SYSTÈME DE NAVIGATION
Abstract
(EN) The present invention relates to at least one air data unit (2) which is located on the air vehicle and enables angle of attack, angle of sideslip and true airspeed data of the air vehicle to be obtained by dynamically measuring air pressure from the air flow; at least one inertial measurement unit (3) which enables orientation, acceleration and angular velocity data of the air vehicle to be measured by means of motion sensors and angle- measuring sensors on the air vehicle; at least one flight computer (4) which enables speed data of the air vehicle to be obtained by processing the data obtained by the air data unit (2); a Kalman filter (5) which estimates speed of the air vehicle by processing the speed data of the air vehicle and the measurement data obtained by the inertial measurement unit (3), which are uploaded to the flight computer (4); at least one global positioning unit (6) which enables real-time speed data of the air vehicle to be obtained by receiving the signals coming from satellites on the earth orbit by means of receivers on the air vehicle.
