Speed calculation with a gyroscope |
| Question: |
In my math book I read that a sometimes a gyroscope is used to measure the speed of, for instance, a plane or a boat. But how does this happen?
I think it's possible to calculate the angel change, then minus the rotation of the earth (in degrees) and then time the circumference of the earth at that height divided by 360. Then you have the way in meters you flew in the time of this angel change. As I said, I'm not sure, so could you help me out? |

| | | Your basically right but it does get a little complex because you need two gyroscopes. One to look after the longitude and one for latitude. Then you have to cross reference the two readings. Then you need to take in account the earth is rotating and the gyroscopes are fixed in relation to space, so is detecting the earth moving. There has been many ways to tackle the problem. I would suggest picking up an old physics book on gyroscopes. Send me an e-mail and I give you a list of the books I have.
