One tyre rotation was just about what my legs did round his port fwd wheelarch after he hit me. I think a shorter drive might well have been the luckier length, Bill, although then he was coming up it.
Big NATO annual exercise on off west coast of Scotland just now, "Ocean Warrior" with GPS jammed.You may find eLoran making a prompt return?
I have just disembarked a bulker in Kalamaki, Greece after a short 2.5 day passage from Haifa, Israel. About 8 hours out of Haifa, when 75 nml south of Cyprus, the vessel suffered severe jamming of all GNSS/GPS signals for a period of 3.5 hours over a distance of about 50 nml. The navigators were prepared for it, as the ship had similar problems a fortnight earlier on the way to Haifa. As a chartless/full ECDIS vessel the system reverted to DR' positions so didn't pose a problem.
This is just one of five GNSS/GPS jamming episodes in various locations that I am aware of over the recent past. A fortnight ago I had experience of false signals on a vessel in the Southern Red Sea/Gulf of Aden over an extended period, there are reports from many vessels of jamming in the Black Sea off the coast of Crimea, off the east coast of Korea and strangely, off the east coast of UK.
Seems that this is a growing problem? Just wait for the mess when signals over the land are jammed!
My experience earlier this year on a trip from Haifa to Greece was a period of severe GPS jamming for about 3.5 hours when around 75 nmiles south of Cyprus. Also had spurious and fast moving unknown radar targets throughout. Vessel had experienced similar two weeks earlier on the inward passage to Haifa. Considering the current military activity in Eastern Med I guess they were the perpetrators?Good,.
Discounting GPS spoofing, which is presently a miniscule risk (and easily detected on commercial tonnage I would claim), I am sure jamming is a reality although I think still more likely at state level than the pirate.
I am surprised that eLoran is considered jam resistant. It would require a lot of power to do it at the same distance as a loran station but I don't think so if closer up.
