There are great demands on the radio spectrum with a lot of people wanting a piece of it. Frodge emphasized the importance of protecting the GPS portion of the spectrum. She recommended a 20 megahertz wide segment of the spectrum to adequately protect the GPS signal, noting some people believe a narrower segment will suffice. Frodge noted there is some confusion at FCC on these issues and they need to be brought to closure. Regarding instrument testing by the Instrument Work Group - One of the major concerns is what the testing means.
Testing is valuable to industry.
They need it for validation. We do not do validation. We need to recognize what needs to be done. The charter of the work group may need to be changed to better address validation. The on-going problem has been completing the reports following the test due to lack of resources.
