Creating virtual global navigation satellite system data for air vehicles using optical interface

In this study, it is aimed to create virtual global navigation satellite system data to be used in cases where the global navigation satellite system (GNSS) data of aircraft are jammed. Today, GNSS data is disrupted by low-cost radio frequency jammer, making devices using GNSS data unusable. In the study, the position information of the aircraft is determined independently from the GNSS data by calculating the slant range, elevation and azimuth angles between the electrooptic based ground station and the air vehicle. In this electrooptic based structure, three different sensors are used. The laser range meter is used to measure the distance between the ground station and the air vehicle, the magnetic field meter is used to measure the angle of the azimuth, and to measure the accelerometer elevation angle. In this study, experimentally, the sensor data obtained from the STEVAL-STLKT01V1 development card were processed and the effect of the measurement errors of the sensors on the position error was analyzed. In this study, methods were provided to the developers of the aided navigation system, and the effect of sensor measurement errors on the position error was analyzed and light was given to the trade off studies.
