10.3 Reviews and Meetings

During the implementation of the contract, some reviews and technical coordination meetings will be held. The specific time and locations are dependent on the program process. Generally the meetings are held in spacecraft side or launch vehicle side alternatively. The topics of the meetings are listed in Table 10-2, which could be adjusted and repeated, as agreed upon by the parties.

Meetings

1

Kick-off Meeting

In this meeting, both parties will introduce the management and plan of the program. The major characteristics, interface configuration and separation design are also described. The design discussed in that meeting is not final, which will be perfected during the follow-up coordination. Kick-off Meeting will cover, but not be limited to, the following issues:

  • Program management, interfaces and schedule
  • Spacecraft program, launch requirements and interface requirements
  • Launch vehicle performance and existing interfaces
  • Outlines of ICD for this program
  • Launch site operations and safety

The ICD will be reviewed twice, preliminary and final. Some intermediate reviews will be held if necessary. Action Items will be generated in the reviews to finalize the ICD for the specific program.

3

Mission Analyses Reviews (MAR)

The preliminary MAR follows the preliminary mission analyses to draft ICD and work out the requirements for spacecraft environment test. The final MAR will review the final mission analyses and spacecraft environment test result and finalize the mission parameters. ICD will be updated according to the output of that meeting.

The review is focused on various interfaces

8

Flight Readiness Review (FRR)

This review is held at the launch site after the launch rehearsal. The review will cover the status of spacecraft, launch vehicle, launch facilities and TT&C network. The launch campaign will enter the fueling preparation after this review.

9
