HTS-E3/1 series high-precision three-axis MEMS gyroscope products are composed of domestic MEMS gyro chip with independent intellectual property rights and its driving pickup circuit, temperature sensor, digital signal processing circuit and control software, built-in all-temperature compensation, installation error compensation and other algorithms, through high-speed RS422 serial port output high-precision measurement data. The products are divided into industrial grade and military grade (working temperature -55℃~+85℃).
HTS-E3/1 three–axis MEMS Gyroscope is a compact tactical grade MEMS gyro module, with ultra high precision (Bias Stability 0.3°/h, ARW 0.15°/√h), which is an affordable, robust and reliable, high accurate MEMS gyroscope.
HTS-E3/1A MEMS Gyroscope is a China-made alternative of STIM210 MEMS Gyroscope module, which integrated with 32-bit micorocontrollers, and electronic axis alignment is by default. Each axis is factory calibrated to calibrate zero bias, sensitivity and compensate for temperature effects, providing high accuracy measurements. The MEMS Gyroscope module is powered by a single +5V supply and communicates via an RS422 interface.
