USCG Vertical UAV Spectrum Issues

This document discusses the spectrum issues related to the US Coast Guard's vertical unmanned aerial vehicles (UAVs), including their electromagnetic emissions, control links, communication radios, transponders, and radar altimeters. The primary objective is to maximize operational effectiveness while minimizing total ownership costs.
