During the GEFFEN 1C Arrival/ILS X RWY 26; we experienced intermittent GPS/ADS-B Signal Interruption due to NOTAM military operations present in the Tel Aviv FIR. Just as we were about to intercept the RWY 26 localizer; we had a Nav Unavailable RNP. Since we were in VFR conditions with 8 miles visibility and the airport area in sight; we continued to intercept the localizer and proceeded to a normal landing. There was some map shift note as compared to the localizer course raw data.
Captain reported experiencing intermittent GPS/ADS-B signal interruption during ILS approach.
