Coming down the FYTTE5 the FMS lost GPS causing the aircraft to continue straight during a turn on the arrival. We noticed the issue and contacted ATC and were then given headings to join ILS Runway 27R. Not much we could have done we saw it as soon as it didn't sequence and contacted ATC to let them know we just experienced a FMS/GPS failure. The newest revision of software we think might have affected the sudden drop in GPS calculation causing us to go off course. We resent the position and then all matched for the points on the approach backed up with the DME for the approach.
Air carrier First Officer reported loss of GPS/FMS navigation capability during the arrival.
