ARS-15 MHD Angular Rate Sensor

The ARS-15 is our newest angular rate sensor designed to fill the gap between the ARS-06 and the ARS-14. With a noise floor of less than 1.0 microradian, small case size, and virtually no sensitivity to linear inputs, the ARS-15 is ideal for low power airborne applications. The ARS-15 is suitable for accurate, compact systems for line-of-sight pointing and stabilization as well as motion control. The ARS-15 has a wide frequency range from less than 3 Hz to more than 1,000 Hz. The scale factor of the ARS-15 is nominally 1 Volt/(rad/sec), but can be customized to meet customer requirements.

 
Custom scale factors and ranges are available.
