Narrative:

After departing uuww for ZZZZ while cruising at FL380 approximately 200 miles northwest of uuww GPS 1 and GPS 2 both failed for about 1 minute then returned to service and then again failed for about 1 minute and again returned to service.no GPS failures occurred prior to or after this specific event. As stated both GPS units failed simultaneously. The airplane's navigational performance did not appear to be degraded by these momentary failures as the airplane is equipped with dual IRS (internal reference system) which were unaffected.no known atmospheric interference occurred and no known GPS satellite outages occurred. In retrospect there may have been some sort of interference associated with the GPS receivers which caused these failure messages. The actual cause is unknown.
