Narrative:

At cruise near turkey/iraq border; lost GPS/ads-b approx. 100 northeast 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 navigation worked fine entire time. VOR worked entire time. Cause probably due to jamming. We were ready ahead of time.
