A simulation study of a possible application of modern control Keyboard/Mouse Combos theory is presented.The problem is to check and calibrate a VOR-station from a circling aircraft.An accurate position estimate of the circling aircraft is needed in order to calculate the errors in the received VOR-signals.The position estimate is here obtained from an integrated navigation system using an inertial navigation system (INS), a laser range-finder, angle measurements on the laser line-of-sight, and barometer readings.
The range and angle measurements are fed to a Kalman filter which estimates errors Stretching in the navigation system.Simulation results show that satisfactory accuracy is obtained by this method.The paper presents a description of the proposed system, the simulation model used, simulation results and some sensitivity analysis.
