... The tracking (i.e. unguided) performance of the United Kingdom Infra-Red Telescope (UKIRT) relies on the accuracy of its 24 bit absolute encoders. These have been long known to generate two systematic errors. The first is a periodic error resulting from the encoder deriving the last 8 resolution bits by interpolation between the rulings on its code disk. ... To estimate the measurement errors we introduce a periodic filter to model and a Kalman filter to model . ...
