Just reading the article rather than relying on other sources, this sounds like the sort of report used to justify one or more additional government contracts in the name of "national security".
To put it another way, the only solution is already known - build critical systems which are not dependent on continuous access to GPS signals. One cannot prevent jambing of a widespread consumer system - the asymmetry of costs and knowledge is too far in favor of the jammer in any civilian case (military solutions to jamming are another matter).
