Another component of the spacecraft arrives at SpaceIL HQ

Meet SpaceIL’s IMU (Inertial Measurement Unit), a major electronic component in our spacecraft’s navigation system. It’s finally arrived at our Yahud offices. The IMU It is meant to measure the accelerations and the angular speed of the spacecraft, resulting from the engines operation, at any given time and situation on the way to the Moon, using accelerometers and gyroscopes.

In our Moon mission, the IMU will perform various measurements during the different spacecraft maneuvers and send feedback on it, as well as during landing and hopping. In addition, the IMU will function as a backup for another electronic component called STR (Star Tracker), in case it is dazzled. It is tiny: Length 38.6 mm, Width 44.8 mm, Height 21.5 mm. In short, the IMU may be small, but important.

Welcome, IMU. We’ve been waiting for you!​
