Precise tracking of unmanned aerial vehicles (UAVs), drones as well as remotely piloted vehicles (RPVs), is the key component for successful automation of take off and landing. Unfortunately, the global available GPS system offers absolute accuracies in the range of some meters only, which is mostly not sufficient. In this contribution we demonstrate the superior performance of the local position measurement system LPM for tracking a remote helicopter during take-off and landing. Based on a least squares (LS) approach for position estimation, the base stations (BSs) are arranged to optimize the error propagation behavior. Measurement results of a remote helicopter proof the applicability of the LPM system to this challenging task.
