Interim Update to the AN/UPX-41(C) Spectrum Certification Conditions (SPS-18778/1)

In 2012, the Navy requested spectrum certification for the shipboard AN/UPX-41(C) Digital Interrogator System, Software Version 5.5 with Mode 5. Current operating conditions for the Navy’s AN/UPX-41(C) are the same as restrictions imposed on the AN/UPX-37 digital Identification Friend or Foe (IFF) interrogator. A proposed AN/UPX-41(C) Stage 4 certification was developed to allow the Navy to operate under less restrictive parameters but required that the Navy and Federal Aviation Administration (FAA) validate those proposed restrictions. In October 2015, the report, DOT-VNTSC-NAVSEA-15-01, was released and detailed the results of the validation effort. Using the information from the validation effort, a more appropriate set of restrictions were developed to specify limits on AN/UPX-41(C) shipborne interrogator activity within 100 nmi of the coastline of the United States and its Posessions (US&P). This document details the rationale behind the new restrictions and gives the new shipborne interrogator geometry relative to the coastline in both a generic and operational manner.
