HTS-IMU-LP1 is an inertial measurement unit (IMU) based on micro-technology (MEMS). The system consists of built-in three-axis MEMS gyroscope, three-axis MEMS accelerometer, three-axis magnetometer and an atmospheric pressure sensor, its pickup circuit, temperature sensor, digital signal processing circuit, structure and software etc.
Features
l Good repeatability, high reliability
l Compact size, low weight, low consumption
l Sensor full element compensation
l Low vibration rectification error
l Cost-effective
