Precision Attitude Determination Subsystem (PADS)

A Marine fires a TOW (tube-launched optically-tracked wire-guided) anti-tank missile during a live-fire demonstration, March 30, 2015, as part of a military exercise at Camp Adazi, Latvia.
Cool photo, looks like it could be some kind of Sci-Fi death ray weapon. Then I notice the odd bar-shaped box on top of the site, the one with the two rounded ends, the thing that looks like it could be a film magazine for a movie camera. Turns out it is a Precision Attitude Determination Subsystem (PADS). Supposedly it uses GPS. If that's the case, I'm guessing the two round compartments on the ends hold GPS antennaes and the length is there to give them enough separation so that their difference in altitude is measurable. Why do you need something like that? Because you could be shooting at something that was 5 miles away.

Looking for info about this device is what led me to the Orion Attitude Control Motor.
