抄録
近年、JAXA、NICT(National Institute of Information and Communications Technology)、国土地理院、国立天文台などを中心とする国内VLBI(Very Long Baseline Interferometry)機関の間で、相対VLBI技術(Delta-DOR)による深宇宙飛翔体軌道決定の高精度化実験が続けられている。国際的にはESAがNASAとは独立に独自のDelta-DORシステムを開発中であり、また、中国の月計画でもVLBIによる飛翔体位置決定を計画中である。このようにVLBI技術による飛翔体位置決定の試みが世界中で隆盛を極めている中、異なる機関間のデータ交換を促すために、宇宙データシステム諮問委員会(CCSDS; Consultative Committee for Space Data Systems)においてDelta-DOR規格の標準化を行おうという機運が高まっている。本稿では、国際的なDelta-DORの動向を踏まえた上で今後の我々の開発方針について示す。

A differential VLBI (Very Long Baseline Interferometry) technology for deep space navigation (Delta-DOR) has been developed in recent years among major Japanese VLBI agencies such as JAXA, NICT (National Institute of Information and Communications Technology), GSI (Geographical Survey Institute) and NAOJ (National Astronomical Observatory of Japan). This technology is also being developed at ESA and China independently of NASA's original system. In order to promote the data exchanges between different agencies, standard processes and message formats for use in the Delta-DOR techniques are proposed in the CCSDS (The Consultative Committee for Space Data Systems). We introduce the main features of this standard, and discuss about the future development plans for upcoming Japanese deep space missions.
