Development of new geodetic coordinate datum management system
(Hainan University,Haikou 570228,China)
Abstract: Current situations of geodetic coordinate datum development procedures and management methods in China were presented. The precisions of astronomic geodetic network and space geodetic network were introduced. Geodetic datum requirements under the current and future new surveying technologies and their applications were discussed. The necessity for upgrading national astronomic geodetic network and development of a new open coordinate geodetic datum management method was investigated.
Key words: geodetic datum； geodetic network； management
