Departure delayed 5 + hrs. In vicinity of ABQ at cruise we got a ATC EICAS. Consulted checklist and inquired to ATC if they still had our transponder. The replied yes and that there was GPS jamming testing being done in the area. This happened to at least one other aircraft in area from listening to radio communications. We then got a GPS advisory EICAS. Again consulted checklist. This has happened in the past and aircraft quickly recovers all systems when you leave area. This time we had ATC and GPS advisory's for the rest of the flight. IRU DME/DME nav only. No safety was compromised and all checklists were referenced. We wrote it up on arrival. I believe aircraft navigation was degraded due to an external source.
An Air Carrier Captain reported GPS jamming.
