Assembly, Integration, and Testing (AIT)

AIT Flow Plan

AIT activities can be further split into subsystem and system level layers. The subsystem level activities are led by the subsystem leads, while the system level activities are led and coordinated by the AIT lead.

• Subsystem-Level Activities: Subsystem assembly and tests are performed by the subsystem leads during phase B and C. These tasks are verifiable through the verification activities that are put together by the AIT and subsystem leads. Once these activities are verified, the subsystems are ready to be introduced to the system.

• System-Level Activities: System assembly and tests are led by the AIT lead in collaboration with the subsystem leads. Before any subsystem is introduced to the system, it shall pass the requirements to interface with other subsystems.

  • 1. FlatSat Tests: These are used to demonstrate functioning interfaces between subsystems and a first demonstration of compliance with the Concept of Operations. The FlatSat test is a major opportunity for the team to identify issues with subsystem interfaces and CubeSat functionality. The electrical and data interfaces are incrementally connected between subsystems and tested to identify possible non-conformances for every subsystem. Once the full satellite function is demonstrated, each subsystem is prepared for satellite integration.

    2. System Integration: Each subsystem is integrated into the structure of the spacecraft within its module. This allows for concurrent use of the available facilities.

    3. System Tests: Once the CubeSat is integrated, a series of tests are undertaken to demonstrate satellite functionality in respective environments. These tests are namely Random Vibration test, Fit Check, Mass Inspection, and Over Air RF Com test, which are verifiable through a set of verification activities coordinated and documented by the AIT lead.

    4. Shipment and Final Functional Test: Once all system level tests are passed successfully, the CubeSat is packaged and shipped to Nanoracks, where the final functional test is performed at the launch facility before the spacecraft is launched.
