    Subject: [NavList 9630] PIM: Precision Indication of the Meridian

    I mentioned a paper published in 1965 by Dr. T.L. Thomas regarding the gyro theodolite: PIM  produced by BAC - British Aircraft Corporation.

    Mr. Peter Hakel  asked for reference to this paper so I have scanned it for perusal here. It might be of interest,  though I hesitate to re-ignite the debate on Coriolis and rotating (Earth) inertial space frames and forces involved.

    It will be useful to have it stored here too for posterity as I expect the original paper is difficult to obtain now.
