Synopsis

Air carrier pilot reported ADS-B and GPS jamming in the area led to faults that remained to destination and required Maintenance to reset GPS receivers.

Narrative

During cruise; SLC Center advised to expect ADS-B and GPS jamming by the military over a wide area. ATC was heard to advise other aircraft that they were not sure how much further along that particular aircraft's route the jamming would last. ADS-B In was displayed as unavailable and GPS 1 and 2 faults were noted. Faults remained to destination. No navigation issues occurred and the flight completed a visual approach to Runway 35C with no issues. During taxi to the gate; a ROW/ROP (Runway Overrun Warning and Protection) fault occurred. Discussed event with outbound crew and expected all navigation to reset after realignment. Maintenance ended up being called out and performed a reset of the GPS 1 and 2 receivers. All faults cleared; operations normal.There is a memo about unexpected GPS anomalies related to certain countries intentionally interfering with GPS signals and possible messages that can be seen. Since this was not an unexpected anomaly from an unknown source; no maintenance logbook entry was made. The memo is somewhat confusing as to if a report is required for experiencing GPS issues in a known NOTAM'd jamming test areas. After consulting with the outbound Captain; the systems were expected to reset after realignment. That effort was unsuccessful and the outbound Captain made a logbook entry. Maintenance reset both GPS receivers and all faults cleared and operations were normal. Clearer guidance from ATC on the area to expect GPS jamming to begin and end along the route is needed as well as clearer guidance on GPS jamming effects on aircraft equipment and when a logbook entry is required.
