In consideration of logistic support for International Space Station (ISS) after retirement of Space Shuttle, next generation manned space vehicle projects are in progress, for example NASA's ORION that is capsule-type space vehicle same as Apollo return vehicle. JAXA's H-II Transfer Vehicle (HTV) successfully conducted logistic support for ISS in 2009, and a study on capsule-type HTV Return Vehicle (HRV) was started, that includes feasibility study on in-orbit demonstration of some technologies for manned space vehicles to return to the Earth. To realize the vehicles which go to and return from space, the reentry is one of the most important technology. Precise reentry guidance technology to guide the manned vehicle to planned touchdown point is an essential technology for fast recovery and crew safety. This paper shows the recent study on precise reentry guidance and control of capsule-type manned space vehicles, including reference trajectory design, system design and key technologies to realize precise reentry navigation and guidance.
