At cruise near Turkey/Iraq border; lost GPS/ADS-b approx. 100 NE of RATVO.  Re-acquired both.  The last 5 to 7 minutes of the loss we were over our RNP of 2.00 (ANP of 2.51). INS NAV worked fine entire time.  VOR worked entire time. Cause Probably due to jamming.  We were ready ahead of time.
B777-200 Captain reported the pilot crew suspected GPS jamming at this location.
