Upgraded Ultra-High Stability Gyroscope Launched

By Mike Ball / 06 May 2021

Silicon Sensing CRS39a gyroscopeSilicon Sensing Systems has launched the next generation version of the company’s ultra-high stability gyroscopes. The new CRS39A is an upgraded version of the company’s established CRS39 gyro, engineered for harsh environments and challenging applications such as UAV (unmanned aerial vehicle) and autonomous vehicle control.

The new gyro is now built on a single board instead of two, reducing the mass of the unit by 40% and making it ideal for space-constrained applications. The CRS39A also incorporates upgraded micro electro-mechanical systems (MEMS) and electronics, including new drive electronics and improvements to the sensor head. These have delivered significant performance enhancements in critical areas such as bias instability, angle random walk, noise and vibration tolerance. Multiple on-board temperature sensors allow performance to be calibrated to suit specific operating environment.

Steve Capers, General Manager at Silicon Sensing Systems, commented: “Our new CRS39A represents a cost-effective and extremely rugged alternative to fibre optic and dynamically tuned gyros. We have refined both the form and performance of CRS39A to deliver a gyro that is ideal for tasks such as down-hole surveying, non-magnetic north-finding, platform stabilisation, ship stabilisation and control, and autonomous vehicle control, as well as for installation in high-end attitude and heading reference systems.”
