Fabrication, Assembly, Integration & Testing of Space Systems

Oak Defense has significant expertise in the assembly, integration, and testing (AIT) of spacecraft, working independently and in collaboration with other aerospace organizations.

Satellite Building Experience

Satellite Categories Supported

Work on three categories of satellites:

Integration & Testing Process

Thermo-vacuum testing
Vibration testing
Acoustic testing
Compact antenna ranging tests
Physical parameter measurements
Dynamic tests
EMI/EMC testing

Expertise and Workforce

Satellite AIT activities require multi-disciplinary expertise, including mechanical, electrical/electronics, and computer science areas. Experienced workforce with domain expertise in these areas carry out satellite AIT activities.

Oak Defense experience and capabilities in satellite AIT activities demonstrate our proficiency in handling complex spacecraft integration and testing processes.

Core Assembly Integration & Testing (AIT) Activities

Oak Defense conducts the following four key AIT activities:

1. Spacecraft Preparations

Preparing the spacecraft for integration and testing processes, including subsystems preparation and setup.

2. Propulsion System, Payload Integration & Testing

Integrating and testing propulsion systems and payloads onto the spacecraft, ensuring proper functionality and compatibility.

3. Assembled Mode Integrated Spacecraft Tests (IST)

Conducting integrated spacecraft tests in assembled mode to verify overall functionality and performance.

Thermo Vacuum, Acoustic, Vibration, EMI/EMC Tests: Performing a series of environmental tests, including Thermo Vacuum tests to simulate space conditions, Acoustic tests for sound vibrations, Vibration tests for mechanical stress, and EMI/EMC tests for electromagnetic interference and compatibility.

These activities are crucial in ensuring the successful assembly, integration, and testing of spacecraft, meeting stringent quality and performance standards.
