So 18 bit encoder is not enough accurate to correct tracking error? if I'm not wrong 2^18 = 262144 ticks /rev and the resolution if encoder on GR2/Final stage should be (360° x 3600)/262144 = 4.49 arc sec, its right? . Can I attach the encoder to GR1 to increase the resolution?
Resolution and accuracy are two different things.
