Selected availability
I presskommunikén från Vita Huset kunde man läsa:
"The decision to discontinue SA is coupled with our continuing efforts to upgrade the military utility of our systems that use GPS, and is supported by threat assessments which conclude that setting SA to zero at this time would have minimal impact on national security. Additionally, we have demonstrated the capability to selectively deny GPS signals on a regional basis when our national security is threatened. This regional approach to denying navigation services is consistent with the 1996 plan to discontinue the degradation of civil and commercial GPS service globally through the SA technique."
Men det är naturligtvis så, att hotbilden kan antas vara USA självt och alla USA:s kompisar (vilket just nu innefattar en stor del av världen). Alltså borde det då vara lämpligt att virra till systemet, helst på några kilometer när, i stort sett överallt. Å andra sidan borde man ju kunna träffa nåt så stort som Pentagon utan GPS, ja, nästan utan allting...
