Guidance
Howard, elsewhere you ask:
- "Apropos "guidance", is anyone more comfortable than I in doing a mathematical introduction to inertial guidance?"
What do you mean by that? To determine the path you need the velocity (direction of movement and value) at every moment (and the geometry of the space, if it is not simply the Euclidean space). --Peter Schmitt 21:07, 4 March 2010 (UTC)
- But accelerometers do not directly give velocity, and real-world inertial guidance systems have substantial error correction, either through gimballing or additional gyros with strapdown. It's not trivial to explain what the six gyros in a typical ring laser unit are doing. Howard C. Berkowitz 21:29, 4 March 2010 (UTC)
