Night VMC with a briefed visual to [Runway] 16R backed up by ILS by Captain (pilot flying). Aircraft is GPS only [no IRS]. Arrival went normal. On base turn on visual approach; both of us saw map shift on ND and the Captain switched to Arc manual data and pressed on. Looking at it on final; my map appeared to shift several miles to right (approx 3) and terrain on GPWS also seemed shifted. [I] tried once to reload with same effect. Then back to pilot not flying duties and an uneventful landing. Entire flight had gone fine for navigation and thus appears to be some kind of GPS jamming event. Aircraft behind us reported nothing; but not sure he understood the question. Multiple NOTAMs are out for GPS jamming right now around the country. We were aware; were set up with backed up raw data; and was a non event.
Air Carrier First Officer experiences a possible GPS jamming event during approach to SLC. Radio navaids are used for a successful VMC approach.
