The Past, Present and Future of Reference Systems for Astronomy and Geodesyuring the past decade has made it necessary to develop reference systems that also include the models and procedures that are used for the analysis of observations by particular techniques. The accurate detemination of the connections between the corresponding reference frames and the adoption of unified standards are major tasks for the future.作者: 發(fā)怨言 時(shí)間: 2025-3-23 02:20 作者: Adulterate 時(shí)間: 2025-3-23 06:11 作者: 高興一回 時(shí)間: 2025-3-23 10:54 作者: Motilin 時(shí)間: 2025-3-23 17:05
