Satellite bus solutions for spacecraft systems

Space and satellite bus platforms, also known as spacecraft or satellite buses, are the structural and functional frameworks upon which various space missions are built. They provide the essential infrastructure and support systems for payloads, power, propulsion, communication, attitude control and other necessary functions to keep the spacecraft operational. Satellite buses also handle a variety of tasks related to data acquisition, storage, processing, and transmission.

Mission requirements, such as payload type and mass, orbit, mission duration, and any unique operational needs drive system design considerations. Optimizing mass and volume distribution is key. And the lighter the platform, the more payload it can carry to its orbit, which contributes to mission efficiency.

System reliability starts with choosing the right components
