Basically compasses are calibrated to their nearest magnetic pole. Northern Hemisphere compasses when taken across the equator drift a substantial number degrees depending on the compass manufacturer. And vise versa
Some cool history, when the British sent their navy to the Falklands their initial barrage was a mile off target because they recalibrated their navigational equipment when they crossed the equator but not their targeting equipment.
Interesting.
Another question I have that i cant figure is:
The earth spins at like 1,000 miles per hour, and it is rotating around the sun at 66,000 mph. The earth is also on an spinning axis. The earth and sun are moving through the galaxy, and the galaxy through the universe.
So why does the pole star never move? Have you ever seen the time lapse picts of the pole star with all other stars spinning around but not the pole star. I dont how that can constantly be the case with all the moving variables.
What am I missing?
The pole stars move 1degree every 73 years with the equipment and if you live long enough you can measure it
The pole stars move 1degree every 73 years with the equipment and if you live long enough you can measure it
So here on earth for nautical navigation; I'm guessing star navigation readings are going to change from compass readings over the centuries?
Wait a degree is a lot, like a real lot. Like 730 years ago the pole would be 10°s different and 20°s in 730 more years.
Do you mean minutes or degrees.
