10m Alignment Measuring Facility

The Alignment Measuring Facility is used to measure either the dimensions of a test item or the mounting positions and angles of all the sensors and antennas on it.
In angle measurement, the mounting directions, angles of sensors and actuators, and other equipment that require orientation accuracy can be measured with high precision.
In positioning, meanwhile, the coordinates of an actuator, which is supposed to be at a specific distance from the center of gravity, or of outermost or protruding parts whose clearance from the inner surface of a launch vehicle fairing is critical, are measured precisely.
Furthermore, a working platform and a tooling bar in the facility allow angle measurements and positioning to the height of 10 m, which enables alignment measurements on small to large spacecraft.
