Narrative:

While flying from maxxo transition point after the departure from sdl; we were tracking towards txo using our FMS. All of the sudden; we noticed that our position was uncertain and that we had no GPS signal. At the same time; we heard other aircraft reporting GPS jamming in the area so we reported experiencing the effects of GPS jamming as well. The ATC thanked us for the report and told us that we showed tracking correctly to the NAVAID. Soon after; we requested a deviation up to 10 degrees to the left to avoid a build up ahead of us. We were deviating for a while and were asked to go direct to txo. We pressed direct in our FMS which showed a 079 track to txo. Then we changed controllers. After about 10 minutes the new controller asked us where we were going. He said that we should be tracking 065 to txo. By then we were quite close to the NAVAID. We repeated that we have FMS issues due to the GPS jamming and he gave us a heading of 095 and told us to proceed direct to our destination when able. We flew the 095 heading for about 15 minutes and once we regained GPS signal we proceeded on course.
