The FAA Flight Inspection Team has been preparing to significantly reduce signal strength measurement uncertainty for several years. Upon reaching the limits of what can be done with a 2D normalization and gain adjustment scheme, the Flight Inspection Airborne Processor Application (FIAPA) now provides added programming flexibility. The FAA has several contracts with Universities to assist with electromagnetic modeling and airborne UAS calibrations. The purpose of this paper is to describe these ongoing efforts.
