Nowadays, there are a variety of different indoor positioning systems employing diverse techniques. Besides inertial navigation, most systems are based on ranging. For instance, techniques utilizing the Received Signal Strength (RSS), phase-difference, time of flight or time of arrival usually convert this information to distances, where trilateration is used to calculate the position. In contrast, approaches utilizing the Angle of Arrival (AoA) are commonly overlooked in literature. Within this paper, we present the hardware design for building such a system and give an outlook towards the algorithms to determine of the AoA. Preliminary measurements show the operability of the system.
