DESCRIPTION
-------------------------------------------------------------------------------------------------------------------------
This instruction manual is the main reference document for the use and operation of IMU3-2A micro gyroscope
combination.The micro-gyroscope assembly can be configured into biaxial or triaxial according to the customer's
requirements. This manual describes the three-axis gyroscope assembly, and the biaxial product also meets the
requirements of this manual.
This instruction manual is mainly prepared in accordance with the Technical Agreement of IMU3-2A Micro
Gyroscope Assembly and the Technical Conditions of IMU3 Inertial Measurement Unit and Triaxial
Gyroscope Assembly.The micro gyroscope assembly is composed of a three-axis gyroscope, a temperature
sensor, a signal processing board, a structure and necessary software, and is used for measuring the
three-axis/two-axis angular rate of a carrier, and outputting three angular rate data subjected to error
compensation (including temperature compensation, installation misalignment angle compensation,
nonlinear compensation and the like) through an RS-422 serial port according to an agreed
communication protocol.
