Would love to hear Hoss183's secret info about how a gyro (laser or otherwise) works. I've only read Honeywells description.
I'm not talking about the align accuracy or time, that is clearly effected by the magnetic / true variation.
CS claimed that the gyro itself wouldn't work at or near the pole because of velocity, that bit is rubbish, a gyro works anywhere including in space.
