High performance Digital MEMS Gyroscopes
Miniature and high bias stability digital MEMS gyroscopes for dynamic applications
High performances digital MEMS Gyros for demanding applications
GYPRO® is a unique family of high performance closed-loop digital MEMS gyroscopes housed in a SMD package. While open-loop MEMS gyros tend to demonstrate poor performances in harsh conditions, the built-in force-rebalance architecture makes our GYPRO® sensors extremely linear and insensitive to vibrations and linear accelerations.
Leveraging a best in-class vibration rejection, excellent bias instability and Angular Random Walk (ARW), GYPRO® is the perfect candidate for precision attitude and angular rates measurement in demanding environments.
The superior bias stability, scale factor repeatability and low latency make GYPRO® an industry-leading sensor solution to build IMU (Inertial Measurement Unit) for high performance attitude and motion control systems as well as INS (Inertial Navigation Systems) for GNSS-aided positioning and navigation in highly dynamic applications.
Seamless and cost-effective system integration
Our GYPRO® digital MEMS gyroscopes feature a 24-bit digital SPI interface that speeds-up their integration compared to conventional sensors solutions. The in-house factory calibration can also remove the need for costly and complex temperature modeling and compensation at system-level. For applications where safety matters, the digital interface integrates both a complete initial self-test as well as a unique continuous in-operation self-test.
Contrary to expensive and bulky solutions like FOG (Fiber Optic Gyros), DTG (Dynamically Tuned Gyros) and quartz gyros, our high accuracy MEMS inertial sensors are housed in a small hermetic SMD package to reduce the overall SWaP-C (Size, Weight, Power and Cost).
For applications requiring both high precision angular rate and acceleration measurement with high bias stability, the GYPRO® gyroscopes are ideally complemented by our AXO® closed-loop digital MEMS accelerometers sensors that feature the same digital interface and SMD package to pave the way to a new generation of affordable high performance multi-axis sensors solutions.
