IMU (Merak-IMU01)
This IMU implements a strapdown architecture using optical gyros and accelerometers, applying calibration compensations before outputting formatted data streams. Deployment scenarios include guided munitions and stabilized platforms requiring precise rate measurements.
Design highlights:
1) Adjustable accuracy/stability balance;
2) Failure-resistant construction;
3) Rapid initialization;
4) Clean digital signal path;
5) Extended mean time between failures.
