Miniature, low-cost Quartz Dual-Axis Rate Sensor (QDARS)Inertial Aerosystems is introducing a new, miniature, low-cost, Quartz Dual-Axis Rate Sensor (QDARS) manufactured by USA-based Systron Donner. Designated the QRS28, it is designed to measure angular movement in two orthogonal axes, featuring simple DC-to-DC operation using two of Systron Donner's MEMS gyrochip rate sensors.

Typical applications will include military and demanding industrial tasks where stabilisation of moving or vibrating platforms is an issue; for example, platform stabilisation, guidance and control, autopilot control, gun and optical line-of-site stabilisation, missile seeker head stabilisation, instrumentation, and fast-slewing, low-noise scanning systems.

This innovative product has no moving parts and is contained in a hermetically sealed stainless steel cylinder, enabling it to be used in hostile environments and applications where high reliability is required. Furthermore, its compact dimensions (26.7mm x 18mm) and low weight (20g) make it useful where space and weight are at a premium. It has low power consumption at less than 0.5W (at 5V DC), with low noise and an operating temperature range of -55 to 85degC.
