Did the US and Saudis use AWACS to help target the SU-24?

A Russian military expert and columnist of the journal Arsenal of the Fatherland explains the details of the downing of the bomber and why not all went smoothly.
How did it all happen?
A U.S. Air Force Boeing E-3 Sentry AWACS plane took off on 24 November from the Preveza airbase in Greece. A second E-3A of the Saudi Arabian air force took off from the Riyadh airbase. Both planes were executing a common task—determining the precise location of Russian aircraft. It is they that picked the “victim.”
The American E-3A was supposed to determine the activity of the Su-24M2’s onboard targeting radar, to determine if it was in search mode or if it had already locked on to a target and was processing launch data. It is known that the AWACS can direct the activity of aircraft in battle, conveying information to their avionics and flight computers.
That is, to determine how defenseless was our plane?
As it turns out, yes. As we know, the Su-24M2 was returning from its mission, and its flight computer was operating in “navigation” mode in tandem with the GLONASS [Russian GPS system.] It was returning to base and was not preparing for action.
The whole time, the E-3s were transferring detailed information about the Su-24M2 to a pair of Turkish F-16CJ’s. This plane [the F-16CJ] had been specifically built for Turkey. Its distinctive feature is a computer that controls a new, AN/APG-68 radar system, and which fulfills the role of a copilot-navigator.
But this information is obviously not enough to precision-strike a small target. Was something else used?
Indeed, the interception accuracy of the F-16CJ fighters was augmented by ground-based U.S. Patriot air defense systems, which are deployed in Turkey, or more precisely, their multirole AN/MPQ-53 radars. The Patriot can work with an E-3 or with MENTOR spy satellites, and it can’t be ruled out that the satellite assets involved the Geosat space system as well.
The flight trajectory of the F-16CJ indicates a precision interception of its target by means of triangulation: A pair of E-3s plus the Patriot’s air defense radar plus the geostationary MENTOR spy satellites plus, possibly, the Geosat space system.
Besides which, the E-3s provided guidance as to the location of our plane in the air; they determined its route, speed, and the status of its weapons control systems; and the Patriot’s air defense radar together with the MENTOR spy satellite provided telemetry on the SU-24M2’s movement relative to the ground surface—that is, it provided a precise prediction as to where our plane would be visible relative to the mountainous terrain.
So it turns out that the Turkish fighters knew with absolutely certainty where to wait in ambush for our plane?
