The optical navigation camera (ONC) system of HAYABUSA2 consists of three framing cameras (T, W1, and W2) with 2-dimensional (1024×1024) charge-coupled devices (CCD's) [1-3]. In
order to gain ΔV and to change the orbital elements, it conducted an Earth swing-by on Dec. 3, 2015. This was a unique opportunity for obtaining images of extended light sources after the launch and before the arrival at the target asteroid Ryugu (1999 JU3).
Because strong vibration during a launch poses the greatest threat to the health of onboard instruments, inflight calibration tests are extremely important for ensuring the quality of the science data.
