Difference between IRS and INS
Hey!
I was wondering if the IRS and INS are one and the same thing. Wikipedia hasn't been of much help on this one. I understand that INS employs gyros and accelerometer and given an initial condition (location) it can compute the current location after factoring in all the changes in velocities and direction since initialization. What about the IRS?
Somebody told me that the INS employs mechanical gyros whereas IRS uses laser gyros. Is that right?
