The Hayabusa2, which is flying closer to the Earth for its scheduled swing-by, photographed the moon and the Earth simultaneously using its onboard Optical Navigation Camera-Telephoto(ONC-T) at 12:46 p.m. on November 26, 2015(Japan Standard Time).
Optical Navigation Cameras.
This is called optical navigation.
This is referred to as"optical navigation.
The orientation error is reduced by using optical navigation.
Optical navigation was used to precisely aim for the asteroid's location.
This observation of the direction of Ryugu from the spacecraft will be used for optical navigation see note 2.
Figure 2: Progression of the estimation accuracy for the orbits of the spacecraft and asteroid made using optical navigation.
The lower right image shows the area that falls within the field of view for the Optical Navigation Camera- Wide angle ONC-W1.
In this post, we show 12 images taken with the ONC-T(Optical Navigation Camera- Telescopic) during the BOX-C operation at approximately 30 degree intervals.
Hayabusa acquired earth images using its onboard optical navigation camera(which is for detecting a relative position to an asteroid and for scientific observations) as it neared the Earth.
The photograph was captured with the ONC-T(Optical Navigation Camera- Telescopic) from an altitude of about 1.9km during the MASCOT separation operation on October 3, 2018 at 05:41 JST.
In this figure, the expected position and trajectory of Ryugu before and after the optical navigation data was used are plotted along with the observation of Ryugu at that time.
September 27,2018 Images of Ryugu photographed during BOX-B operation The deployment was captured with the optical navigation camera ONC, which was developed and operated in part by UoA professor C. Honda.
The Int-Ball project adopts an optical navigation technology called"Phenox" developed by the Artificial Intelligence Laboratory at the University of Tokyo, and body control using a 3-axis reaction wheel developed by the Research and Development Directorate of JAXA.
Several times since NASA's OSIRIS-REx spacecraft entered orbit around its target asteroid Bennu on Dec. 31, 2018, the OSIRIS-REx team detected multiple, bright, point sources near Bennu in the optical navigation(OpNav) images obtained by the spacecraft's NavCam 1 imager.
Figure 1: The work loop for optical navigation. Image credit: JAXA In Figure 1, the first four teams listed on the far left accurately measure the position of Ryugu with respect to the background stars from the image captured by the ONC-T.
The spacecraft reached an altitude of about 600 m from the surface of Ryugu and then began to ascend once again. During the operation, the images taken for navigation purposes with the Optical Navigation Camera Wide angle(ONC-W1) were released in real time.
The technologies recognized for this award included the spacecraft's ion engine navigation, the deep-space orbit design and guidance technology such as the swing-by and optical navigation, deep-space communication and navigation technology such as DDOR and Ka communication, advanced technology including the solar sail attitude stabilization and the deep-space optical link.
Initial version of the shape model for Ryugu| ISAS We previously introduced a global image of asteroid Ryugu, but the Hayabusa2 Project shape model team have also created three-dimensional models of the asteroid. The asteroid was measured using images captured with the ONC-T(Optical Navigation Camera- Telescopic) to form a"shape model" of Ryugu.
