Angular rate sensor offers fast start-up and high bias stabilityInertial Aerosystems is introducing the QRS116 angular rate sensor for military applications and other demanding projects. This high-performance micromachined sensor is manufactured by Systron Donner Inertial (SDI) and it is claimed to offer reduced noise, faster start-up and unprecedented angular random walk and in-run bias stability.

The excellent performance of this sensor is based on SDI's proven quartz MEMS sensing element, which provides superior bias stability and repeatability. The bias variation with temperature is 20 degrees per hour and short-term bias stability is three degrees per hour.

This innovative product has no moving parts, which ensures a long service life and high mean time between failures (MTBF), while the electronics are self-contained. The input voltage is +/-5V DC with an operating temperature range of -55 to 85degC. It is also capable of withstanding 1000 'g' shocks.

Suitable for use where space and weight are at a premium, the QRS116 angular rate sensor is packaged in the same dimensions as the industry-standard QRS11, measuring 38mm diameter and 15.38mm in depth, and weighs 60g.

Applications include stabilising antennas, weapons platforms, flight controls, navigation, instrumentation and advanced robotics.
