SMU200
High performance inertial sensor for HAD systems
Application & Technical Summary
SMU200 features a single-axis yaw rate sensor (Ωz) and a 3-axis accelerometer (axyz).
Typical applications include localisation by combining the GNSS position information with the sensor’s data, resulting in a significantly more precise positioning. The combination of a SMU200 with two SMU210 makes a system capable of measuring all 6 degrees of freedom (yaw, pitch and roll rate as well as acceleration in x, y and z direction).
Product benefits
- On-board safety controller for monitoring of sensor functions
- Excellent offset stability over the entire temperature range
- Developed according to ISO26262 for systems with safety targets up to ASIL D
Target applications:
- Localisation
- Other ADAS functions
