<p>This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.</p><p>The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.</p><p>By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.</p><p>The control unit will sense its own direction by a magnetic sensor that works as an electronic compass. The Pan/Tilt-controller will then rotate the link to reach the targets coordinates. Alternatively you can control the position of the link manually by the GUI.</p><p>The report also discusses the functionality of the sensors and tests have been conducted to determine the accuracy of the control unit. The Pan/Tilt-controller can rotate a link 360º around its own axis and also tilting the link ±90º. The Pan/Tilt-controller can direct a link towards a target with an accuracy of 5º -10º.</p>
