Narrative:

Approaching salt lake (slc) we were planning on an RNAV arrival. As we started our descent we were given the; non RNAV; jammn 4 arrival and told that the GPS signal was being jammed. Shortly after we lost both GPS systems.we continued the descent using our back up DME/DME system and cross checking our position using vors. The descent and arrival was uneventful other than the loss of all GPS capability.on landing I checked the notams again and also checked our [filed online] flight plan to see if it was indicating we should have had GPS raim (receiver autonomous integrity monitoring). There were no notams we could find and no indication of proposed GPS signal loss. We are wondering why jamming is taking place with no notams filed? While the flight was uneventful; in our opinion it should be notamed anytime the GPS system will be out of service. All other flights around us were also reporting the loss of all GPS.

Title: C525 is informed by ATC prior to descent into SLC that GPS jamming is occurring and a non RNAV arrival is assigned. After landing the NOTAMs are checked and none can be found for the jamming event.
