Performance

The ASC 273 is a triaxial MEMS vibrating ring gyroscope developed for precise angular rate measurement in industrial and automotive environments. It features configurable ranges from ±75 °/s to ±900 °/s, with low bias instability of 12 °/hr and angular random walk of 0.2 °/√hr. Thanks to its balanced ring design, the ASC 273 offers excellent shock and vibration rejection, while its anodized aluminum housing ensures lightweight durability.

Usage conditions

The ASC 273 operates across −40 °C to +85 °C with stable sensitivity and bias over temperature. With an IP67 protection rating, case isolation and rugged design, it provides reliable performance in harsh environments. It withstands shocks up to 500 g (operating) and 10,000 g (survival). Custom connector and cable lengths are available.

Possible applications

Precision navigation and pointing systems
Automotive in-car navigation and yaw/pitch/roll rate sensing
Dead reckoning GPS aiding for vehicles and personal navigation
Motion tracking and gesture sensing
Precision agriculture UAVs and AGVs
Camera, antenna and platform stabilization
Industrial robotics and automation

Advantages of choosing this sensor

With its triaxial measurement, low noise and robust housing, the ASC 273 reduces the need for multiple uniaxial sensors, saving space and integration costs. Its high stability, wide bandwidth and customizable configuration make it a versatile solution for navigation, guidance and stabilization systems.
