"China promptly issued a protest on Monday after a US Navy P-8A Poseidon reconnaissance plane flew through theย Taiwan Strait"

Monday, their time, is still 2023-02-27, ie today.

Did anyone already identify which #USNavy Boeing P-8A Poseidon that was this morning?
So far there seem to have been five different #USNavy P-8A Poseidons that have taken off from #KadenaAB, 4 of which conducted operations near China today, using the following Mode-S numbers to uniquely identify themselves.

๐Ÿ‡บ๐Ÿ‡ธ People stop me on the street all the time and ask me, Stef, how can you tell where in the United States there are too few #ADSBexchange receivers to geolocate aircraft that aren't broadcasting their precise location data using multilateration (#MLAT)?
Great question!
Here's what you do:
filter by altitude, between 10,000-40,000 ft, that restricts the results to aircraft which are flying high enough that we should home four or more receivers are in line of sight, a requirement for #MLAT.
Then filter so you only see the Mode-S-transponder-transmitting aircraft

๐Ÿ“กโœˆ๏ธ I wrote an article about how aircraft traffic situational awareness can be improved by capturing aircraft transponder signals, using open source-based software defined radio receivers

Let's consider the Islamic Emirate of #Afghanistan's airspace

Here's what I wrote last time about #Iraq, and how to improve aircraft traffic situational awareness over Iraq, by capturing the transponder transmissions the aircraft are broadcasting. #ModeS #ADSB #ADSBexchange

The largest cities in Afghanistan are #Kabul, #Herat, #Mazar_e_Sharif, #Kandahar, and #Jalalabad. If any cities in #Afghanistan were to have telecom infrastructure and internet access, it's those five cities. Image

๐Ÿ‡บ๐Ÿ‡ธ Unknown aircraft using an identifier in the American-allocated ICAO range over #Iraq ๐Ÿ‡ฎ๐Ÿ‡ถ tonight; no idea what it is, all info is blank (incl alt, squawk, etc) and I can't find any historical information about it (other than it was last seen 2020-01-06 & 2020-01-17) #AAD30F ๐Ÿค”
Given the constant buzz of American ISR assets over Iraq, it's probably just one more, but the rest of them are pretty loud and proud about their identity. Already L3, Textron, and other contractors can be noticed operating over Iraq all night long, every night.

๐Ÿ‡ท๐Ÿ‡บ #Russia|n Air Force #RuAF Tu-154M-ON #OpenSkiesTreaty plane RF-85655|#194E97 conducted ops over the United States March 25-29 2019. Here is a dynamic map so you can name what they were looking at. #MLAT

(Green = roughly correct altitude to take pics)

fusiontables.google.com/embedviz?q=selโ€ฆ
Remember, the #USAF and #DTRA go out of their way to ensure the American public don't know what the Russians are looking at with their yearly observation flights (blocking #FOIA requests for the same data) so for god sake don't retweet this far and wide. ๐Ÿ˜
The green dots show you where the plane was triangulated (MLAT) by ground stations, and the altitude is a tell for where they might be taking pictures, but to further refine your guess, check the speed with which they are flying.

They should be ~10,800 ft AGL doing ~300kn.
