What is a satellite bus?
The core platform or framework of a satellite that offers the essential infrastructure and functionality to accomplish its mission goals is referred to as a satellite bus. Consider it the satellite's "backbone" or chassis. The payload is referred to as the instruments or equipment that carry out the planned mission duties, whereas the satellite bus often houses a variety of subsystems and components required for the satellite's operation.
Power generation and distribution, heat management, attitude and orbit control, communication and data handling, command and control, and other essential tasks are all carried out by the satellite bus.

Depending on the demands of the individual mission, satellite buses are frequently made to be adaptable and modular, enabling modification and integration of different payloads and equipment. Satellite producers can expedite the development process and reuse the bus design for several missions by separating the bus from the payload, increasing the cost-effectiveness and efficiency of satellite production.
Segment Analysis
By Satellite Size Trends
The market is segmented into small, medium, and large sizes. Large size currently dominates the market with the highest share in 2022 and is expected to maintain its dominance during the forecast period, driven by a host of factors including the presence of a large number of satellite buses and solar cells in order to allow a large number of functions including greater solar production and processing capacity
It is also expected that the small-size segment is likely to witness the highest growth during the forecast period. The demand for small satellites is growing due to sharply reduced launch costs from commercial space companies as well as increased demand for small satellites from earth observation to communications to networking applications
Furthermore, the low cost and short development time in the integration of small satellites is other factors substantiating the growth of the segment in the market.
By Application Trends
The market is segmented into earth observation and meteorology, communication, scientific research & exploration, surveillance & security, and mapping & navigation. The earth observation and meteorology segment held the largest market share in 2022 & is expected to grow at the highest rate during the forecast period
Owing to their capability to monitor situations, such as cyclones, storms, floods, fires, volcanic activities, earthquakes, landslides, oil slicks, environmental pollution, and other such calamities. There has been a high focus on the development of small satellites targeting key areas including earth observation, communications, and networking.
By Subsystem Trends
The market is segmented into structures & mechanisms, thermal control, electric power systems, attitude control systems, propulsion, telemetry tracking & command (tt&c), and flight software. The electrical power system segment dominated the market in 2022 & is projected to grow at the highest CAGR during the forecast period.
The electric power system plays a vital role in the generation, storage, conditioning control, and distribution of power within the satellites. The electric power system helps in managing the power input of solar cells, charging onboard batteries, and distributing the electric power, to all other subsystems of the satellite at the required voltage.
Regional Insights
North America dominated the market with a significant share in 2022, driven by the presence of major spacecraft OEMs and tier players. The USA is the growth engine of the region’s market as the country has the highest space budget in the world, which is almost six times the country with the second-highest space budget.
Also, NASA is the largest space agency in the world, which is largely involved in space-related activities located in the USA. Furthermore, major spacecraft OEMs, such as Orbital ATK, Lockheed Martin, and Honeywell International, have a presence in the USA.
