The rendezvous and landing missions are very significant for scientific explorations. In such missions, the navigation and guidance based on image data is very important. The spacecraft Hayabusa performed the descent flights to the target asteroid Itokawa in November of 2005. To accurately determine the spacecraft position, a landmark tracking scheme with the help of the ground operation was introduced...
Recently small body exploration missions have received a lot of attention in the world. In small body explorations, especially, detailed in-situ surface exploration by tiny probe is one of effective and fruitful means and is expected to make strong contributions towards scientific studies. JAXA/ISAS is promoting MUSES-C mission, which is the worldpsilas first sample and return attempt to/from the...
Hayabusa spacecraft performed the final descents and touchdowns twice in November 2005. In final descent phase, terrain alignment maneuvers were accomplished to control both altitude and attitude with respect to the surface by using four beams Laser Range Finder onboard. Then Hayabusa spacecraft made dynamic touchdowns the surface of the asteroid by the sampler system to collect samples automatically...
The Japanese asteroid exploration spacecraft Hayabusa autonomously performed touchdown two times in November 2005. The autonomous guidance and navigation capability is installed aboard the spacecraft. The GNC system collects the laser altimeter, laser range finders and navigation cameras information aboard and is designed to estimate where the spacecraft is and to decide the path correction maneuvers...
