Captain reported GPS signal loss in ORBB foreign airspace caused distractions which resulted in them failing to send a mandatory position report.

Narrative

'While over southern Turkey approaching Iraq Airspace we first experienced intermittent Right Transponder messages. The Left was tried and it also produced messages. Then we experienced the loss of GPS Signal (iPads as well) and finally communication with Baghdad Control became very garbled. The flight plan did indicate the possibility of these events happening in this airspace because of the ongoing military activity. The interference lasted for approximately XX minutes and there were no incidents/problems because of it. However; I had prepped a company position report to send at RATVO intersection. Due to the distraction with communications; GPS and the Transponders; I failed to send the position report. I did not realize the error until we were on the ground. Cause: Distraction due to interference with navigation and communication.Suggestion: Double check company procedures especially when non normal conditions occur. We may or may not have received a dispatch request for a position report during the time of communication interference. When the X hr requirement was not met; Dispatch should have been following up for it.
