Introduction
This standard belongs to China Aerospace national standards. China Aerospace national standards applicable to national standards in the field of aerospace and revision
Management, covering the management of space, space technology, space applications and services of the three fields, is to guide spacecraft and launch vehicle project management, engineering research
System, space launch services, in-orbit satellite applications based activities.
Geosynchronous communications satellite into orbit after launch, usually go through a period of in-orbit tests, the satellite platform and payload
The function and performance tests using test data related to satellites in orbit flight conditions were assessed when a user with a total of Cheng Zhifang
When the same evaluation results confirm the flight in orbit to meet the requirements specified in the contract communication satellite, the satellite can be delivered to the user. To ensure the same planet
Step orbit communications satellites flying objective and impartial evaluation of results, and user and can be co-sanctioned Cheng Zhifang, it is necessary to clarify and standardize the relevant assessment
In accordance with the principles, methods and evaluation project, which has great significance for the geostationary orbit communications satellite development and delivery.
Geosynchronous communications satellite flight evaluation of results
1 Scope
This standard specifies the principles of geosynchronous communications satellite flight results assessment, based grading, projects, methods and rating
determination.
This standard applies to satellite development department before geosynchronous orbit communications satellites to deliver user since the satellite separated from the rocket, according to the in-orbit testing
Evaluation results are given flight data.
