In response to this request, RTCA's Program management Committee has tasked Special Committee 159, Global Positioning System (GPS), to develop a response. Special Committee 159's next recommended submission, the Second Interim Report titled Ultra-Wideband Technology Radio Frequency Inference Effects to Global Positioning System Receivers and Interference Encounter Scenario Development, is being produced in two phases:
