Abstract

This paper presents an experimental procedure for aerodynamic characterization of a delta-wing UAV for model-based navigation applications. We report the design of experiments, aimed to maximize aerodynamic coefficients observability while meeting time constraints requirements, as well as the significance of secondary aerodynamic influences. A functional model, simple yet accurate, is derived from the experiments. We evaluate it empirically in-flight with an offline-implemented navigation solution during GNSSsignal outages, using data exclusively collected from low-cost sensors embedded in a commercially available autopilot. Results showed that the model-based navigation solution produced a significantly smaller positioning error compared to traditional navigation approaches during GNSS outage.

Automotive navigation system

An automotive navigation system is part of the automobile controls or a third party add-on used to find direction in an automobile. It typically uses a satellite navigation device to get its position data which is then correlated to a position on a road. When directions are needed routing can be calculated. On the fly traffic information (road closures, congestion) can be used to adjust the route.

Inertial navigation system

An inertial navigation system (INS) is a navigation device that uses motion sensors (accelerometers), rotation sensors (gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors (magnetometers) and/or speed measuring devices.

Global Positioning System

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
