NavChipTM
At roughly the size of a penny, the NavChipTM employs ground breaking MEMS technology to provide unprecedented low noise and stability. As the industry's first commercial IMU chip, the NavChip represents a 12-fold improvement in angular random walk and a 6-fold improvement in bias in-run stability compared to previous commercial-grade MEMS IMUs.
The NavChip will enable advanced inertial navigation applications, including GPS/INS integration previously limited to large-scale military vehicles, to be deployed on small unmanned vehicles such as UAVs and robots. It will also allow the miniaturization of camera and antenna stabilization systems in both fixed and mobile applications.
NavChip Features
- World's smallest 6-axis IMU
