5 Data user classification and management
5.1 User classification
According to data user attributes and their data application purposes, data
users are divided into the following 5 categories:
a) Exclusive data user: the chief scientist or project leader, unit or
organization that has the exclusive right to use the data;
b) Public-welfare data user: individuals, units or organizations that use space
science data to develop scientific research or public-welfare applications;
c) Business data user: individuals, enterprises or institutions that use space
science data to develop business applications and provide value-added
d) International data user: foreign individuals, physical organizations or
institutions that acquire and use China's space science data to develop
scientific research and application, which is divided into international
cooperative data user and international business data user according to
data user attributes;
e) Public user: users other than those mentioned above.
5.2 Data user management
Different data user management processes are different, as follows:
a) Exclusive data users have the right to preferentially use data according to
the regulations of the authorized administration;
b) Public-welfare users and international cooperative data users need to
submit applications; the executive administration shall conduct user
2) Arrange experiments/ exploration plans for feasible requirements;
acquire, process and archive data;
3) Provide processed data products.
6.2.2 Emergency service

a) Acquire emergency data requirements; initiate a rapid response
b) Provide archived data products which are required for emergency;
preferentially provide online data;
c) Arrange emergency experiments/ exploration plans in time to achieve
programming data acquisition;
d) According to the development of the emergency, terminate emergency
data product services.
6.3 Service methods
6.3.1 Online services
Online data product services:
a) Publish standard data products and metadata, notification requirements,
tool software, etc.;
b) Data push service, user data exchange and submission, data sharing;
