The IMU05-S (RLVBIMU05-S) is an advanced inertial measurement unit that provides precise roll, pitch, and yaw rate measurements using the best MEMS high-precision gyroscope. Its zero bias stability is only 0.8 deg/hr.

When used together with VBOX as an inertial navigation system, RLVBIMU05-S seamlessly integrates IMU data with GNSS to obtain accurate position, velocity, and vehicle attitude angles. This integration ensures reliable measurement even in the event of satellite disconnection or interference.
