## Discrepancy

APPROXIMATELY ONE HOUR AFTER TAKEOFF AND ENROUTE, CREW REPORTED BACK TO MX THAT BOTH GPS RECEIVERS HAD LOST THE SATELITE FIX AND HAD STARTED TO REACQUIRE.  CREW ALTERED THEIR FLIGHT PATH TO RETURN AND APPROX 10 MINUTES LATER BOTH GPS HAD REACQUIRED THE SATELITES AND AGAIN ALTERED THEIR COURSE TO RESUME THE PLANNED ITINERY. MAINTENANCE INVESTIGATED IF THERE WERE ANY SATELITE ISSUES THROUGH THE AUGUR RAIM PREDICTION TOOL ONLINE (HTTP://AUGUR.ECACNAV.COM/) AND ONLY SHORT PERIODS OF MX WERE NOTED FOR THE APPROACH RAIM AND NONE FOR ENROUTE. CURRENTLY, THE ACFT REMAINS AWAY FROM BASE AND A COMPLETE DEBRIEF FROM THE AIRCREW WILL FOLLOW.
