A satellite bus is a central power or data distribution network that houses thermal control, telemetry tracking and command, electric power system, attitude control system, and propulsion system. Spacecraft bus manufacturers build it according to customers’ requirements and depending on the type of payload it carries. Manufacturing of the satellite bus focuses mostly on three main objectives, payload carrying capacity, payload lifting power allocation, and heat dispersal of the spacecraft bus.

For instance, in March 2021, Airbus was awarded a two-year A/B1 contract worth USD 3.4 million to study in-space manufacturing under the PER ASPERA In-Orbit Demonstration (PERIOD) project under Horizon 2020 Programme by European Commission. It will focus on the in-space manufacturing of space-based components such as satellite assembly components, antenna reflectors, and satellite payload replacements.

The aerospace industry has been hit hard by the ongoing COVID-19 pandemic. However, market research has indicated moderate growth in 2020 and growth is expected during the forecast period.

• The budget of a government or commercial market operator to develop or launch a space industry has been reduced due to budget variations to prevent the spread of the ongoing pandemic and related infrastructure costs.

• After the commercialization of the space industry, new entrants to the space industry strongly emphasize the usefulness of small satellites. Global companies are also focusing on using constellations of satellites in commercial and military applications.

• According to the U.S. Department of Commerce, about 92% of airlines with RandD are small businesses. These companies have experienced a significant impact from COVID-19, which is expected to return to normal after 2021.

Satellite Bus Market Trends

High Adoption Rate of Satellite Constellation for Various Applications Due to Improved Reliability to Boost Market Growth

Over the last decade, the space industry has witnessed a high adoption rate of small satellites or satellite constellation applications in military and commercial domains. This adoption of satellite constellation for applications such as ISR (intelligence, surveillance, and reconnaissance), satellite communication, earth observation, and telemetry applications, satellite-based internet services has been driven by the proximity of the constellation to the earth's surface and high reliability than the traditional single satellite utility for various applications.

These satellite constellation-based internet services will facilitate uniform coverage worldwide, lower launch cost, off-the-shelf availability of the critical components. These factors influence the rise in space launches carrying various payloads, cargo, and crews to the earth's orbit.

Satellite Bus Market Growth Factors

Increased Satellite Launches due to High Adoption Rate Across Commercial and Military Sectors to Drive Market Growth

Space systems and satellite infrastructure require many components to help provide imaging solutions, communications, signals, and other solutions that enhance satellite capabilities. After the introduction of nano, micro, and small spacecraft buses, the traditional components used in the technology are more expensive. In addition, additional space infrastructure, such as ground tracking stations and related components, is required. These factors are expected to curb the growth of the market.

According to its recent market study on Satellite Manufacturing, it has been estimated to launch more than 10,000 small satellites by 2026 into the Low Earth Orbit (LEO). It also highlights the rising trend of the partnership between private small and microsatellite manufacturers and government agencies. Despite the dwindling reliability of the medium and heavy satellite during the forecast period, the high demand and adoption rate of spacecraft buses for commercial and military applications have driven the market growth during the forecast period.

Rise in Space Exploration Missions and Decrease in Space Launch Cost to Propel Market Growth

The commercial space exploration cost is anticipated to decline as smaller launch vehicles facilitate smooth access for potential space market entrants. Market’s key players and governmental organizations emphasize additive layer manufacturing (ALM) to manufacture space-based products and services. The decrease in space launches is anticipated due to the advent of reusable launch vehicles and rise in space exploration programs.

Over the last decade, governmental space organizations have been emphasizing interplanetary space exploration such as the Moon, Mars, and other cosmic objects and the launch of space-based telescopic satellites encased in the buses for space exploration.


High Maintenance Cost and Unavailability of Critical Components during Pandemic to Affect Growth

According to the NASA study on Error Cost Escalation through Space Project Life Cycle, the study showcases the degree of cost escalation in detecting and resolving errors and delay in satellite manufacturing. Cost of Error resolution is 1 unit of space system cost factors at the requirement stage, 3-8 units at designs stage, 7-16 units at the manufacturing stage, 21-78 units at integration and testing stage, and 29-more than 1500 units at operations stage.

The design complexity and the integration of multiple satellite instruments and subsystems in large-size satellite manufacturing involve many errors at various stages of its life cycle. This factor is the main factor in increasing cost escalation for error resolution at different stages.
