We were descending via the SNDIA 4 for the ILS Runway 8. Passing ASIDE intersection I noticed that my MFD (Multi Function Display) screen when zoomed in didn't exactly match the Captain's side. As we continued down the arrival we received a clearance for the ILS 8 approach. Going through about 8;000 feet both the Captain and I were looking at a very large discrepancy now between our two screens. The autopilot was coupled to the Captain's side so it was still following what we thought was the correct track. I switched to green needles in anticipation for the turn to the localizer off the transition route and now noticed we were flying through the localizer but our FMS still had us at the previous point prior to the turn. Both the Captain and I were unfamiliar with the airport especially at night; so we were planning on flying the full approach. ATC then asked us to report any GPS issues; which I had responded with yes we believe we have lost GPS; looking for vectors.At this time I had gotten visual contact with the runway as well as the Captain who was flying. We both agreed that due to our current location it was best to discontinue the approach and try again. We went around and got vectored around. The second approach had no issues as we got vectors to final off the localizer. It was later found out that the military was jamming the GPS signal. We also received a terrain INOP yellow message displayed on our MFD's for a few minutes but no associated EICAS message. A GPS signal lost was never displayed on either FMS. We do not know how long or how far off course we were on the arrival as it appeared okay on our end; and ended up missing the turn to the localizer as our FMS was telling us we were several miles behind our current position. ATC needs to be aware of potential military GPS jamming so they can provide that information to the pilots. We did not see a NOTAM in ABQ for jamming either. Given it also being night around terrain; ATC should have provided vectors from the beginning and not the RNAV arrival since GPS signal could not be guaranteed.
An Air Carrier pilot reported GPS jamming caused an unstable approach at night. The reporter stated the jamming was a known issue but they were never advised and ATC vectored them to an RNAV Approach.
