Evil Sid Posted October 9, 2020 Report Share Posted October 9, 2020 The bermuda triangle is well known for things getting lost never to be seen again. Sat navs are notorious for sending you in the wrong direction as well. But a thought has been nagging at the back of my mind. What if you used a sat nav in the bermuda triangle? Would they cancel each other out so you did not get lost or would they amplify the effect and make you get lost quicker?.........🤔 Quote Link to comment Share on other sites More sharing options...

Observer II Posted October 9, 2020 Report Share Posted October 9, 2020 There was a prog about ships compasses being distorted in the Atlantic, off the coast of S/Africa. The anomoly was put down to fluctuations in the Earth's magnetic field, which can flip over hundreds of years. Quote Link to comment Share on other sites More sharing options...
asperity Posted October 9, 2020 Report Share Posted October 9, 2020 The difference between True and Magnetic compass reading is called Magnetic Variation which is noted on all navigational charts and which is taken account of by navigators when plotting their courses. The magnetic poles drift all the time which means the variation alters all the time, on top of which the earth is covered with areas of Magnetic Anomalies where the variation is distorted by geological factors. These anomalies are also taken into account and special charts are printed and updated all the time. Quote Link to comment Share on other sites More sharing options...

asperity Posted October 9, 2020 Report Share Posted October 9, 2020 It's the law that one of the most vital pieces of equipment a ship has to carry is a magnetic compass, well maintained and periodically checked. Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted October 10, 2020 Author Report Share Posted October 10, 2020 t may sound daft that but if you think about it lack of power or a power source will not stop it from working. Still got my map compass from when i was a boy sprout. That still works after fifty years. No gps then or sat nav, come to think of it no sats apart from sputnik......

asperity Posted October 10, 2020 Report Share Posted October 10, 2020 That is exactly why all sea-going ships have to carry a magnetic compass Sid. There were quite a few satellites orbiting the earth 50 years ago, Sputnik was launched 63 years ago in 1957! 👩🚀 Interestingly the USA's first satellite, Vanguard 1, was also launched in 1957 and is still in orbit 63 years later! 🛰️ Quote Link to comment Share on other sites More sharing options...
Evil Sid Posted October 10, 2020 Author Report Share Posted October 10, 2020 i only know about sputnik as it was the year i was born. exactly a week after i was born to be precise.......My claim to fame. Quote Link to comment Share on other sites More sharing options...
