Aircraft
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 RWY 17. I told him we were direct to the airport. Controller opted to give us vectors for the visual approach.
Small transport Captain reported GPS Navigation accuracy degraded after experiencing Jamming earlier during flight.
