Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by China Aerospace Science and Technology Corporation. This standard by the National Aerospace Technology and Standardization Technical Committee (SAC/TC425) centralized. This standard was drafted by China Resources Satellite Application Center. The main drafters of this standard Yu Wenyong, Liu Guodong, Kang Qian, Song Shuhua, Wu Jun, Liu Mingliang, Qin Jingfang. Terrestrial Observing Satellite Ground System Data Transmission and exchange interface requirements

1 Scope

China's national standard for the data transmission and exchange interfaces within a land observation satellite ground system. It specifies the interface requirements between the processing system and the receiving systems, the tracking and control systems, and the users. A satellite ground system is several large systems built by different organisations at different sites: antennas that receive the downlink, a control centre that commands the spacecraft, processing chains that turn raw telemetry into products, archives that hold them and portals that serve them. Each is a substantial system in its own right, and the programme works only if data crosses between them without loss or ambiguity. Interfaces are also where such programmes usually fail, because each side is built to its own schedule against an assumption about the other. Writing the interfaces down as a national standard rather than as a project document means the next satellite can reuse the ground segment instead of rebuilding it.

This standard specifies the land observation satellite ground system processing system and receiving systems, measurement and control systems, data transmission between users, pay Change the interface requirements. This standard applies to land observation satellite ground system (hereinafter referred to as satellite ground system) data transmission and exchange, other remote sensing satellite ground Surface system can also refer to use.
