There is probably a very sinister reason the Russians didn't want the British Navy anywhere near the waters of Sevastopol on Wednesday. On Wednesday more than 20 Russian aircraft and two coastguard ships shadowed HMS Defender as it was sailing off the coast of Crimea. Moscow's defence ministry said a patrol ship fired warning shots and a jet dropped bombs in the Royal Naval ship's path.
HMS Defender left Russian waters soon after the incident on Wednesday, having ventured as much as three kilometres inside Russian waters. (Sophisticated military equipment doesn't "venture" three kilometres off.)
There is something very mysterious going on, in and around the waters of Sevastopol in the Black Sea and the Russians have been going to incredible lengths to cover up this mystery since the Summer of 2017.
What happened to the British Navy ship on Wednesday the 23 of June 2021, is just the latest in a number of "strange events" in the Cape Fiolent waters of the Black Sea. In June 2017, U.S. Maritime Administration reported that GPS HDOP, Horizontal Dilution of Precision (Global Positioning System) was 25 nautical miles off course. In the same year, hundreds of dead dolphins and birds have been and still are washing up in the same area. (many many more will have died out at sea) Did the British Naval vessel's GPS reading fail placing the British Ship ship in Russian waters unintentionally?
On the 4th of September, 2017, TBW reported a strange event that happened in the Black Sea area of Novorossiysk, Russia (about 120 miles West of the British Navy incident) when the U.S. Maritime Administration reported that, GPS HDOP, Horizontal Dilution of Precision (Global Positioning System) was showing 0.8 accuracies within 100m, but given the ship's, location, was actually 25 nautical miles off; GPS display. It was an apparent mass and blatant, GPS spoofing attack involving over 20 vessels in the Black Sea which had navigation experts and maritime executives scratching their heads.
(The event happened on June 22, 2017, at 0710 GMT almost exactly 4 years earlier than the British Navy incident.)An apparent mass and blatant, GPS spoofing attack involving over 20 vessels in the Black Sea has had navigation experts and maritime executives scratching their heads. The event first came to public notice via a relatively innocuous safety alert from the U.S. Maritime Administration: A maritime incident had been reported in the Black Sea in the vicinity of position 44-15.7N, 037-32.9E on June 22, 2017, at 0710 GMT.
This incident has not been confirmed. The nature of the incident is reported as GPS interference.
The master replied: Thank you for your answer, nevertheless I confirm my GPS equipment is fine.
We ran a self-test a few times and all is working good.
I confirm all ships in the area (more than 20 ships) have the same problem.
I personally contacted three of them via VHF, they confirmed the same.
Sometimes, the position is correct, sometimes is not.
GPS sometimes loses position or displays inaccurate position (high HDOP).
For few days, GPS gave a position inland (near Gelendyhik aiport) but the vessel was actually drifting more than 25 NM from it.
Important: at that time, the GPS system considered the position as "Safe within 100m".
Then last night, the position was correct despite several "lost GPS fixing position" alarm that raised couples of seconds only; then the signal was back to normal.
Now the position is totally wrong again.
Note: you can also check websites like MarineTraffic and you will probably notice that once in a while all ships in the area are shifting inland next to each other.
I hope this can help.
To back up his report, the master sent photos of his navigation displays, a paper chart showing his actual position and GPS-reported position, and his radar display that showed numerous AIS contacts without corresponding radar returns (below).
One of the photos was of the navigation receiver’s “GPS Information Screen.”
This has allowed navigation experts to conclude this was a fairly clear, if not subtle, case of “spoofing” or sending false signals to cause a receiver to provide false information.
They point to the receiver saying its antenna is 39 meters underwater, that all the GPS satellites it is using have the same high signal strength, and that the WER, or Word Error Rate, is 97 per cent (normal is less than 10 per cent).
The RNT Foundation has received numerous anecdotal reports of maritime problems with AIS and GPS in Russian waters, though this is the first publicly available, well-document account, of which we are aware.
Russia has very advanced capabilities to disrupt GPS.
Over 250,000 cell towers in Russia have been equipped with GPS jamming devices as a defence against attack by U.S. missiles.
And there have been press reports of Russian GPS jamming in both Moscow and Ukraine.
In fact, Russia has boasted that its capabilities “make aircraft carriers useless,” and the U.S. The Director of National Intelligence recently issued a report that stated that Russia and others were focusing on improving their capability to jam U.S. satellite systems.
