英文摘要 |
The behavior of future LAMOST mount tracking is one of crucial issues for the telescope’s overall performance. In order to demonstrate and to sense the real situation to some degree, the LAMOST team has set up a model mount at the camps of Nanjing Institute of Astronomical Optics & Technology. Painstaking effort has been made during the course of the interim outdoor test to improve the accuracy of the model mount tracking. The major test progress, starting from scratch to date, has been recorded in this paper, such as the anti-disturbance measures taken, the cascaded feedback application,the two-motor-differential drive till the overhaul of the model mount in its drive mechanism, etc. The tracking accuracy has been dramatically improved up to 0.35"-0.42" RMS, promising the future LAMOST tracking requirement will be met given more reliable mount and sophisticated control system. |
