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 fibre-optic and dynamically tuned gyros. The latest inductive MEMS gyro sensor element is bined 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 pensation 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. © Copyright 2013 Silicon...
