Alignment determination of the Hayabusa2 laser altimeter (LIDAR)

Hirotomo Noda, Hiroki Senshu, Koji Matsumoto, Noriyuki Namiki et autres

Abstract In this study, we determined the alignment of the laser altimeter aboard Hayabusa2 with respect to the spacecraft using in-flight data. Since the laser altimeter data were used to estimate the trajectory of the Hayabusa2 spacecraft, the pointing direction of the …

Dynamic precise orbit determination of Hayabusa2 using laser altimeter (LIDAR) and image tracking data sets

Keiko Yamamoto, Toshimichi Otsubo, Koji Matsumoto, Hirotomo Noda et autres

Abstract The precise orbit of the Hayabusa2 spacecraft with respect to asteroid Ryugu is dynamically determined using the data sets collected by the spacecraft’s onboard laser altimeter (LIght Detection And Ranging, LIDAR) and automated image tracking (AIT). The LIDAR range data and …

Experiments of inverted pendulum as a vertical reference of a telescope

Hideo Hanada, K. Asari, Seiitsu Tsuruta, Ken-ichi FUNAZAKI et autres

We propose an attitude control system for a telescope utilizing an inverted pendulum. We put a tube with a sharp bottom end on an XY linear translation stage, and surround the top by a ring with 4 pressure gauges inside. We made …

A method for attitude control of telescopes making use of an inverted pendulum

Hideo Hanada, Seiitsu Tsuruta, K. Asari, Ken-ichi FUNAZAKI et autres

We propose an attitude control method of a telescope using an inverted pendulum. A cylindrical telescope tube with a sharp bottom end is put on a motorized XY linear stage. The upper edge of the tube is supported by 4 pressure sensors. …
