Happy New Year 2023
Happy New Year Everyone!
Had to go ahead and set my watch notifications for this thread being I check it a few times everyday fairly religiously.
That's a ground vehicle. The tower tracks them using ground radar ASDE-X. Not very technical I know... The N number appears to end in XB and is reserved.Okay, I know this isn't Milair but what is it? Noticed it at IAD/Dulles when I was checking ADSB-Exchange, whatever it was it was on the ground doing 28 mph --

Airport Surface Detection System — Model X (ASDE-X).
The data that ASDE-X uses comes from the following sources:
By fusing the data from these sources, ASDE-X is able to determine the position and identification of aircraft and vehicles on the airport movement area, as well as aircraft flying on final approach to the airport.
- Surface surveillance radar located on top of the air traffic control tower and / or surface surveillance radar located on a remote tower
- Multilateration sensors located around the airport
- Airport Surveillance Radars such as the ASR-9
- Automatic Dependent Surveillance — Broadcast (ADS-B) sensors
- Terminal automation system to obtain flight plan data.
Washington Dulles International Airport (IAD) is one of the airports that use this.

The long-range radar could be critical for keeping an eye on Chinese activities and is another sign of growing U.S. vigilance in the Pacific.
U.S. Building Advanced Over-The-Horizon Radar On Palau
A description of TACMOR from the FY23 USAF budget papers:
A remote, unattended Transmit site consisting of ten elements and high power amplifiers transmitting High Frequency (HF) Skywave Over-The-Horizon Radar (OTHR) waveforms. The transmit site will also consists of a HF vertical sounder antenna and a HF backscatter sounder providing ionogram information for optimizing frequency selection.
A remote, unattended Receive site consisting of 128 dual-monopole antenna elements receiving the over-the-horizon reflected energy from the transmit site. The receive site also contains the secure facilities for signal processing of the received data and real-time target extraction information.
This effort will also fund the communications infrastructure necessary to enable the data flow from the Transmit and Receive sites to an off-site operations control center.
The operations control center plans and executes missions in support of the Combatant Command (CCMD) and provides real-time, target tracking information to all-source information fusion and dissemination systems. TACMOR data will also be accessible to and exploited by the National Air and Space Intelligence Center (NASIC) for detailed, post-event analysis.

Latest update of milair freq & callsign lists
Okay, I know this isn't Milair but what is it? Noticed it at IAD/Dulles when I was checking ADSB-Exchange, whatever it was it was on the ground doing 28 mph --
When I was in the Air Force in the late 80's I was assigned to the OTH-B in Maine. When that was up and running it was amazing to see how they could pick an object out and track it. I can only imagine from that time to now how the technology has improved and what they will be able to do!!Guys
