Re: IRS question
Cribble,
If there is movement, there will be a difference in actual light path equivalent to the distance moved by the inertial platform in the linear direction of the path (rotation doesn't come into it). As I said, I left out a lot of other considerations. If you want more, can I suggest going to the Honeywell or Northrop-Grumman (makers of Litton IRS) websites.
