Design and implementation of small integrated navigation system for UAV

摘要

The design and implementation of a low cost, light weight, but at the same time reliable and accurate integrated navigation system is key issue at UAV platform development. This paper presents some details on the integrated navigation system functioning algorithms, including initial correction of low-cost accelerometers and gyros, barometric altitude calculation, algorithms of autonomous Strapped down Inertial Navigation System functioning and its correction by means of Global Navigation Satellite System, magnetometer and barometric altimeter data. The results from the car test of the integrated navigation system have been presented.
