Narrative:
Approximately 30 minutes into the flight; at cruise; we received an ATC fault message and complied with the QRH. We switched from the left to the right transponder with no resolution to the defect. We asked ATC if they were still receiving our information and they said they were. About five minutes later we received terr position; GPS; runway system; and unable rnp messages. We complied with the QRH for the messages. We worked with ground operations and ATC to verify appropriate equipment code; and determined we could proceed to destination. Goc satcom patched to us for coordination; this was helpful and timely. Approximately 30 minutes later all the messages went away. We landed uneventfully at destination. Caused by apparent failure of the GPS system. This aircraft has multiple events in its history of related problems.
