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.

Table 10-2 Reviews and Meetings




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


Interface Control Document Review (ICDR)

The purpose of the ICD Review is to ensure that all the interfaces meet the spacecraftís requirements.

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.


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.


Spacecraft Safety Reviews

Generally, there are three safety reviews after the three submissions of Safety Control Documents. The submittals and questions/answers will be reviewed in the meeting.


Launch Site Facility Acceptance Review

This review is held at the launch site six months before launch. The spacecraft project team will be invited to this review. The purpose of this review is to verify that the launch site facilities satisfy the Launch Requirements Documents.


Combined Operation Procedure Review

This review will be held at the launch site following the submission of Combined Operation Procedures, drafted by the customer. The Combined Operation Procedure will be finalized by incorporating the comments put forward in the review.


Launch Vehicle Pre-shipment Review (PSR)

This review is held in CALT facility four months before launch. The purpose of that meeting is to confirm that the launch vehicle meet the specific requirements in the process of design manufacture and testing. The delivery date to the launch site will be discussed in that meeting. CALT has a detailed report to the customer introducing the technical configuration and quality assurance of the launch vehicle. The review is focused on various interfaces


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.


Launch Site Operation Meetings

The daily meeting will be held in the launch site at the mutually agreed time. The routine topics are reporting the status of spacecraft, launch vehicle and launch site, applying supports from launch site and coordinating the activities of all sides. The weekly planning meeting will be arranged if necessary.
