Comparison of different methods of flight data logging used in multirotor UAVs

摘要

This paper describes the comparison of different methods of flight data logging in multirotor unmanned aerial vehicles. Solutions u-sed in commercial avionics systems are presented and compared with the current design developed by authors. Based on the literature and analyzed examples, requirements for two separate logging systems are formulated. This approach allowed to modify current solutions and develop new methods for the high frequency data logging. Three different memory storages were considered for this task - SD card, RAM and e.ternal NAND Klash. Based on the theoretical calculations, developed prototypes and performed e.xperiments, the best solution was selected.
