Protect the Frequencies – By preventing interference
Toughen Receivers – With readily available technology
Augment Services – With difficult to disrupt terrestrial signals
Our Challenge
Much of the world depends upon satellite systems for precise navigation and timing services. These are exceptionally accurate and dependable, yet GPS/GNSS jamming, spoofing, and other forms of interference appear to be growing in frequency and severity. Neither are space systems immune to severe space weather or cyber-attack. This has the potential for devastating effects on our lives and economic activity.
