In this paper, we discuss the design of a sliding-correlator channel sounder for 28 GHz propagation modeling on the NSF POWDER testbed in Salt Lake City,UT . Beam-alignment is mechanically achieved via a fully autonomous roboticantenna tracking platform, designed using commercial off-the-shelf components . Enhanced with real-time kinematic correction streams, our geo-positioning subsystem achieves a 3D accuracy of 17 cm, while ourprincipal axes positioning subsystem achieves an average accuracy of 1.1degrees across yaw and pitch movements .
