16. The turntable computer has the ability to store the data related to the operation of the turntable, such as time, turntable position and angular rate, and has the ability to output data in real time through the serial port. The output frequency is ≥ 5Hz. Capable of controlling the operation of the turntable and the temperature through an external computer (through a serial port). Communication protocol: RS232 9.6Kbs. The rear panel of the electric control box is provided with a standard RS232 serial interface.

single-axis multi-function turntable is used for various position, rate and swing tests and detection of rate gyroscope and its inertial measurement unit. The turntable can also be used for the performance test of inertial navigation devices and inertial navigation systems under high and low temperature conditions after the temperature control box, temperature control system and auxiliary shaft are purchased.

The main functions are as follows:

1. Position control, speed control and swing control functions;

2. It has the functions of computer automatic state control, data acquisition, processing and display.

3, with speed limit setting and overspeed protection functions;

4. The full temperature test can be carried out after the temperature control box, temperature control system and auxiliary shaft are equipped.
