About the CRS39A Gyroscope
CRS39A provides the optimum solution for applications where bias instability, angle random walk and low noise are
of critical importance.
At the heart of the CRS39A is Silicon Sensing’s VSG3QMAX vibrating ring MEMS sensor which is at the pinnacle of 15 years of design evolution and the latest off a line which has produced over 30 million high integrity MEMS inertial sensors. The VSG3QMAX gyro sensor is combined with precision discrete electronics to achieve high stability and low noise, making the CRS39A a viable alternative to Fibre Optic Gyro (FOG) and Dynamically Tuned Gyro (DTG). CRS39A has been designed for mounting within a 25mm inside diameter cylinder. Two on board temperature sensors and the resonant frequency of the MEMS enable additional external conditioning to be applied to the CRS39A by the host, enhancing the performance even further. CRS39A provides improved performance and hysteresis over the established CRS39-03.
