A Reverse-Design Strategy for the Track Error of the Qi Tai Telescope Based on Pointing Accuracy
The Qi Tai Telescope (QTT), which has a 110 m aperture, is planned to be the largest scale steerable telescope in the world. Ideally, the telescope’s repeated pointing accuracy error should be less than 2.5 arc seconds (arcsec); thus, the telescope ...
