KSIMU03D inertia unit is shown in Figure 4

Figure 4 Appearance of the IMU

The KSIMU03D is installed with three Φ4.4 through holes and three M4 screws (spring washer and flat washer). When the connector is installed, the plug should be locked with the socket and the cable should be fixed. It is recommended that the flatness and verticality of the installation surface relative to the base plane be no more than 0.02mm, no more than 0.04mm, and no more than 0.8μm of the surface roughness.

Spatial Coordinates:

Right hand rule principle 1

The MEMS IMU contains three axial spatial coordinate systems, namely X, Y and Z. The X-axis points to the direction of the electrical connection interface, the Y-axis points to the left side of the IMU, and the Z-axis points to the top surface of the IMU, as shown in Figure 1.

Figure 1 IMU Spatial coordinate

The installation of the IMU must match the axis of the coordinate system, otherwise the measured angular velocity data is not accurate. Following the "Right Hand Rule principle 1", you can quickly assign and determine the axis of the coordinate system. Extend your right hand and expand your thumb, index finger, and middle finger respectively. The thumb is pointing in the X-axis direction, the index finger is pointing in the Y-axis direction, and the middle finger is pointing in the z-axis direction, as shown in Figure 2.

Figure 2 Principle 1 of the right-hand rule

Right Hand Rule Principle 2

The three-degree-of-freedom gyroscope in the IMU measures angular velocities in three directions. Following the "right hand rule principle 2", the angular velocity direction of the axis rotation can be quickly determined. Stretch out the right hand and spread the thumb. The direction of the thumb is the axial direction, and the direction of the other four fingers is the direction of the axial rotation of the thumb, as shown in Figure 3.

Definition of heading Angle, pitch Angle and rolling Angle

Pitch angle definition: Taking the X- axis as the rotation axis, counterclockwise is positive, horizontal is zero, and the range is [-90º, 90º].

Roll angle definition: Taking the Y axis as the rotation axis, counterclockwise is positive, horizontal is zero, and the range is [-180º, 180º].

Course angle definition: Taking the Z axis as the rotation axis, counterclockwise is positive, north is zero, and the range is [-180º, 180º].

Electrical Characteristics:

The electrical connector model of KSIMU03D is J30JE-15ZKN-J, and the corresponding connector model is J30J-15TJ. Contact specific distribution is shown in the table below.

Communication protocol

The communication interface is RS422, with 8 data bits, 1 start bit, 1 stop bit, and no verification; the high byte is first and the low byte is last. The default baud rate at power-on is 460800, and the data update frequency is 500Hz.

Applications:

Automotive electronics refers to the electronic systems used in vehicles to enhance their functionality and performance. These systems include electronic control units (ECUs), sensors, actuators, and communication devices that work together to regulate various aspects of the vehicle's operation.

Aircraft guidance and control systems are critical to the safe operation of aircraft. These systems use advanced technologies such as GPS, autopilots, and flight management systems to help pilots navigate, maintain altitude and airspeed, and land safely.

The attitude reference system is a key component of aircraft guidance and control. It provides accurate information about the aircraft's orientation in space, which is essential for maintaining stable flight and navigating accurately.

Platform stabilization is used in a variety of applications, including cameras, telescopes, and radar systems. It involves the use of sensors, motors, and control systems to keep the platform steady and pointed in the desired direction, even in the presence of external disturbances.

Robot and antenna stabilization systems are used to keep these devices steady and pointed in the correct direction. They use advanced sensors and control algorithms to detect and compensate for external forces and disturbances, ensuring accurate and reliable performance.
