GGSP - ISDC

The main function of the GGSP (Galileo Geodetic Service Provider) is to provide a terrestrial reference frame, in the broadest sense of the word, to both the Galileo Core System (GCS) as well as to the Galileo User Segment (all Galileo users). This implies that the GGSP should enable all users of the Galileo System, including the most demanding ones, to access and realise the GTRF with the precision required for their specific application. Furthermore, the GGSP must ensure the proper interfaces to all users of the GTRF, especially the geodetic and scientific user groups. In addition the GGSP must ensure the adherence to the defined standards of all its products. Last but not least the GGSP will play a key role to create awareness of the GTRF and educate users in the usage and realisation of the GTRF.

GGSP（伽利略大地测量服务提供商）的主要职能是在最广泛的意义上，为伽利略核心系统（GCS）及伽利略用户段（所有伽利略用户）提供陆地参考框架。这意味着GGSP应确保伽利略系统所有用户，包括需求最为严苛的用户，能够以符合其特定应用所需精度的要求访问并实现GTRF（伽利略大地参考框架）。此外，GGSP必须确保向GTRF的所有用户，尤其是大地测量和科学用户群体，提供适当的接口。除此之外，GGSP还需确保其所有产品均遵循既定的标准。最后，GGSP在提升GTRF的公众认知及教育用户如何使用和实现GTRF方面将扮演关键角色。
