For some time I've spotted the Portland (Oregon, USA) Police Bureau Cessna 182T boring holes in the sky over Portland. What has made this seem unusual is that in past flights its ADS-B was misconfigured and did not broadcast its registration (N-number) as if it was trying to operate incognito (see the above screen capture). Of course, the "hex code" (ICAO) always came through and I could translate it to its N-number. This afternoon the aircraft departed the the Portland area, broadcast it's N-number, and flew to my home airfield (7S5, Independence, OR) where it landed and parked near the on-field restaurant. (Hey, cops gotta eat too <g>.) This was my chance to see the aircraft in person and snap some pictures. At first blush, it's a pretty unremarkable C182T. except for a lot of antennas and some sort of sensor on the left side: Even the dataplate is consistent with the "incognito" image: The panel was unremarkable but I could not examine it in detail due to the tinted windows and the sun angle. I could not spot an autopilot or even an EFIS (all round gages). The Portland Police Bureau has at least one other aircraft (a C172) flying around in incognito mode but I've never seen it on the ground.
Eye in the Sky pod - Electro-Optical Imaging. Your picture isn't hi res enough for me to ID the make / model, but Airborne Systems for Government & Defense | Teledyne FLIR is the big maker of these devices.
