Electronic Gyro

We developed an electronic gyro for a client, using MEMS technology. The main design features are:

32 gyros are used to improve the drift and accuracy.
A Peltier cooler is used to keep the MEMS ICs at 25°C, which is where the drift is zero.
The Peltier cooler operates in a closed loop regulator mode, using PWM to regulate the temperature.
Advanced signal processing is used to further improve the stability and accuracy.
The unit is available us purely a gyro, or as a gyro and accelerometer combination.
