Introduction

A satellite housing is the primary structural enclosure of a spacecraft.

Its mission is much more complex than simply protecting electronics.

Satellite Housing=Lightweight Structure+High Precision Structure+Mission Critical Structure

A satellite housing must: Support onboard equipment Maintain structural integrity during launch Resist vibration Resist thermal cycling Reduce weight Provide accurate assembly interfaces During launch, a satellite may experience: High VibrationAcoustic LoadsAcceleration LoadsSpace Environment Therefore:

What Is A Satellite Housing?

Every interface must be precisely machined.

A satellite housing acts as the framework that supports: Electronic modules Communication equipment Sensors Batteries Payload systems Thermal control assemblies Typical architecture: Payload ModuleElectronics ModuleBattery CompartmentStructural Housing
