The paper presents development of prototype of integrated inertial-satellite navigation system that contains 3-axis accelerometers, gyros, magnetometers, barometric altimeter and GNSS (Global Navigation Satellite System) receiver. Navigation system testing procedure by means of flight at airdrome at small remotely piloted aircraft system (RPAS) is described, and data processing details with results are submitted. These results received from the data post-processing had approved the efficiency of integrated navigation system functioning in normal navigation mode, i.e. during availability of GNSS measurements. It has been shown as well that after approximately 10 s of autonomous MEMS inertial navigation system (INS) functioning accuracy of velocity and position calculation degrades significantly.
