GPS Discussed at National Space Council Meeting


On October 5, the revived National Space Council held its first meeting, featuring speakers from the civil, commercial, and national security space sectors. The Council, chaired by the Vice President and composed of members of the Cabinet, is tasked with advising and assisting the President on national space policy and strategy.

GPS was mentioned during the meeting by former NASA Administrator Michael Griffin, who said, “With regard to GPS and frankly other elements of our critical infrastructure, we need to be extremely clear that an attack on these assets is an attack on the United States. We need to do everything we can to proliferate GPS-derived but GPS-independent methods of capturing and preserving our timing signals and our navigational information.”
