The US National PNT Advisory Board reaffirmed its position on allowing signals in frequencies near the GPS/GNSS spectrum in a letter posted to its site yesterday.

Dated July 5th, the letter essentially restates information the board provided to the deputy Secretaries of Defense and Transportation in the last administration. The board was careful to note that it had just reviewed the issue again at their June 2017 meeting.

The board summed up their view and recommendations early in the three page letter:

“The policy choices before the government are:

1) Protect current and evolving uses of GPS, military and civilian, as a matter of national priority, or

2) Approve high power terrestrial mobile broadband application in frequency bands adjacent to the GPS that
would very likely cause harmful interference to both government and private sector GPS applications.

We as your Advisory Board recommend the first choice.”
