1. INTRODUCTION
1.1
Purpose of this Manual
This section of the Servo System User Manual contains a description of the pointing error
model of the AMiBA Hexapod Telescope at Mauna Loa, Hawaii.
The pointing error model is used to eliminate known systematic pointing errors caused by
non-linearities, deformations, temperature variations etc. A description of the hexapod
kinematics is contained as well.
The compensation algorithms themselves are implemented in the Pointing Computer
(PTC). Any accessible parameters can be modified at the PTC, see part 3 of this User
Manual (description of PTC Local User Interface).
1.2
Software Identification
This Error Model Description describes the algorithms as implemented in the PTC
software version:
