The Epson three-axis accelerometer sensor HGPM01 can be used in applications such as driverless vehicles and phased array antennas

 HGPM01 Can be used in unmanned vehicles and phased array antenna applications.

 HGPM01 Is a module developed based on the high-performance gyroscope sensor and accelerometer, with a built-in 3-axis gyroscope and 3-axis accelerometer sensor. Relying on high precision sensors, high performance processors and advanced digital signal processing algorithm, the module outputs a very stable angular velocity value and acceleration value. Modules can support either SPI or UART data communication.

 Phased array antenna is a kind of antenna array with electronic steering function, which can change the direction and shape of radiation signal without the physical movement of the antenna. The precise positioning of such electronic steering cannot be separated from angular velocity and acceleration measurement. The navigation deviation, roll and pitch of the antenna will affect the accuracy of the positioning system, and due to the existence of three axes, the calibration difficulty of the positioning system is doubled.

 With the increasing accuracy of the phased array system, the radio frequency spectrum is increasing, the independent array design is getting bigger and bigger, and the system needs a higher performance inertial measurement unit (IMU) to support it. Antenna orientation error may come from spectral density, RMS, velocity random walk, offset repeatability, cross-axis sensitivity, etc., so it is particularly important to choose an appropriate inertial measurement unit (IMU).

EPSON (Epson) joint third party launched inertial measurement unit HGPM01 is based on high performance gyroscope sensor and accelerometer development, built-in high performance triaxial gyroscope, triaxial accelerometer, can output high precision air deviation, roll, pitch Angle data and three-dimensional rotation Angle speed, three-dimensional linear acceleration data, real-time temperature. Using IMU to detect the antenna can overcome the disadvantages of large inertia and slow speed when rotating the antenna by mechanical method.

3. Other precautions

● Installation Angle of the module, please try to install horizontally, the normal line of the module is parallel to the rotation axis of the machine

● The module must be installed reliably to ensure that it is not loose during work

● The module should not be close to the heat source, heat or heat change areas, such as power, motor drive power, main MCU, these places usually the heat is more severe, and cold and hot uneven

● In the process of operation, try to smooth, avoid large collisions, avoid sudden rotation of large angles, try to follow the (stop, accelerate, uniform, deceleration, stop), to ensure the smoothness of the movement
