GPS attitude system

Abstract [en]

Determination of attitude is to compute the orientation in space of a body. As an example, it could be about determining the heading of a boat or the angle of a slope on which a vehicle is parked. A common purpose of an attitude determination system is to serve as a sensor providing input to systems for automatic control. A relative direction, based on change of position, is easily computed by a single GPS receiver. A more accurate solution, independent of movement, for attitude determination can be produced using an array of two or more antennas, attached to clock-synchronized GPS receivers. The scope of this thesis has been to implement and verify an attitude determination algorithm. The algorithm has been implemented in Matlab and has been designed for post- processed collected data. Testing and validation of the algorithm was performed using both stationary and dynamic GPS data. The results indicate a functional algorithm that has been verified via the collected data. In the dynamic data the points where it is possible for the algorithm to operate are rather scarce, but the accuracy in the operable points is satisfactory.
