Three Axis Rate/Postion Turntable
Introduction
ER-PRT-03 Three Axis Rate/Postion Turntable is mainly used for testing and calibration of inertial navigation system, and can also be used for testing of unit devices such as gyro, accelerometer and other inertial devices. It adopts vertical UOO or UUT structure in general. It uses brushless DC torque motor to drive directly, absolute encoder is used as angle feedback, and the control system adopts modular design. It can rotate in three directions: azimuth, pitch and roll. The motion mode includes position, speed and swing.
There are aviation connectors on the turntable surface or frame for user signal transmission. The turntable control cabinet provides standard RS232/422 serial interface, network interface and other interfaces. It can be designed as horizontal UOT structure as required.
