IMAGE-BASED GUIDANCE, NAVIGATION, AND CONTROL FOR MUSES-C SAMPLE AND RETURN SPACECRAFT

摘要

The sample and return spacecraft MUSES-C is required some autonomous image-based navigation functions to approach, rendezvous, and land the asteroid safely. This paper describes the guidance, navigation, and control system of MUSES-C, mainly focused on its onboard image-processing functions. After brief explanation of the rendezvous and sampling scenario of MUSES-C mission, required onboard hardware specifications and image-processing algorithms are summarized. Present status of the development of the system and some pre-flight test results are also reported.
