Satellite
Bus Market Overview
In the
fast-evolving space economy, the satellite bus often called the backbone or
platform of a satellite is becoming a strategic differentiator for innovation,
mission success, and cost-efficiency. As the foundation that houses critical
subsystems like power, propulsion, thermal control, and communications, the
satellite bus plays a vital role in the performance and lifespan of every
orbital mission.
According to
a recent market study, the global Satellite Bus Market Size is expected to reach USD USD
9.27 Billion by 2030, registering a CAGR of 5.96% during 2024-2030. This growth
is driven by the surge in satellite launches for telecommunications, earth
observation, military surveillance, and emerging applications like satellite
internet and IoT connectivity.
A satellite
bus, also known as the satellite’s body, houses all of the necessary satellite
components and associated scientific equipment. Satellite buses are essential
as they are responsible for taking the satellite equipment safely into space.
Understanding
the Satellite Bus
The satellite
bus is the infrastructure that supports the payload (the instruments or sensors
that perform the mission). It includes subsystems such as:
·
Electrical
Power Supply (EPS)
·
Thermal
Control System (TCS)
·
Attitude
and Orbit Control System (AOCS)
·
Propulsion
Units
·
Telemetry,
Tracking & Command (TT&C)
A
well-designed bus ensures reliability, scalability, and modularity—factors that
are increasingly critical as missions demand faster deployment and longer
satellite lifespans.
