ARS-14 MHD Angular Rate Sensor

The ARS-14 is our most sensitive angular rate sensor, designed to work in a variety of high-performance applications, such as line-of-sight stabilization and precision motion control systems. The  ARS-14 has sub-nanoradian angular resolution and low sensitivity to linear acceleration inputs making it ideal for use in highly dynamic environments such as aerial and ground-based vehicles. The ARS-14 also features low power consumption making it a candidate for application where power is limited. The assembly is compact, rugged, and capable of handling environmental extremes without affecting performance. The ARS-14 can be space qualified. The ARS-14 has a wide -3dB frequency range from less than 2 Hz to more than 1,000 Hz. The scale factor of the ARS-14 is nominally 20 Volt/(rad/sec) but can be customized based on customer requirements.
