Narrative:
About 30 miles north of abq area; lost GPS signal due to jamming on our way to apa. GPS signal was recovered but perhaps not complete accuracy. Indeed; when arriving and asked to proceed direct to the airport (apa) the autopilot track was off; aiming about 3 miles north of the airport. Controller believed we were tracking direct to a fixed on final approach course of GPS runway 17. I told him we were direct to the airport. Controller opted to give us vectors for the visual approach.
