1 General Description
CRS39 provides the optimum solution for low angular
rate range applications where bias instability, angle
random walk and low noise are of critical importance.
CRS39 is available in two forms; the unpackaged
version which has been designed for mounting within
a 25mm inside diameter cylinder, and a packaged
version for general applications where ease of
mounting is required.
The outstanding stability, low noise and size of the
CRS39 makes this a viable alternative to bre-optic
and dynamically tuned gyros.
The latest inductive MEMS gyro sensor element
is combined with precision discrete electronics to
achieve high stability and low noise.
Three on board temperature sensors and the resonant
frequency of the MEMS enable additional external
conditioning to be applied to the CRS39 by the
host, enhancing the performance even further. Test
data for Bias and Scale Factor can be provided with
each gyroscope enabling this compensation to be
implemented without the need for further calibration.
Typical applications include downhole surveying,
precision platform stabilization, ship stabilisation, ship
guidance and control, autonomous vehicles and
high-end AHRS.
