Space-Based Cube Satellite Industry Analysis
In the ever-evolving world of space technology, cube satellites have emerged as a significant player, promising affordable and versatile space access. However, the industry faces several challenges that require ongoing innovation to sustain and accelerate its growth.
Cube satellites, with their compact design, are being deployed for communication applications such as worldwide Internet of Things (IoT) services, internet coverage, and machine-to-machine communications. The global cube satellite market is expected to reach a revenue of $275.8 million by 2025, driven by favourable government policies for the commercial use of space and rising investments and budgets in space and cube satellite projects.
However, the high requirement of technical expertise acts as a barrier to the entry of new players in the cube satellite industry. The sensitivity of cube satellites' electronic components to stray radiations reduces the sampling capabilities of sensors, thereby hindering the market. The major challenges in the hardware design of CubeSats primarily revolve around thermal management, power systems, and reliable onboard computing in the harsh conditions of space.
Thermal Management
CubeSats are exposed to extreme temperature variations in space without atmospheric convection, making it difficult to keep components within safe operating ranges. Novel cooling solutions, such as wax-filled heat sinks, have been tested to regulate waste heat in electronics and improve operational time, but managing heat remains a critical design challenge.
Electrical Power Systems (EPS)
CubeSats rely on compact, efficient EPS comprising solar panels, batteries, and power conditioning modules. Designing these systems to generate, store, and distribute power reliably under variable sunlight exposure is complicated, demanding careful simulation and mode scheduling to optimize power usage.
On-Board Computing
The on-board computer (OBC) must process payload and system data, schedule subsystems, respond to errors autonomously, and store data for transmission. It needs to be robust, low-power, and fault-tolerant given limited resources and the space environment’s harshness.
These hardware design challenges impact the global CubeSat market by increasing development complexity and costs, driving the need for innovative thermal and power technologies, and necessitating collaboration across academia, industry, and space agencies.
The global cube satellite market is consolidated, with key players including AAC Clyde Space, Planet Labs, Capella Space, Sierra Nevada Corporation, Surrey Satellite Technologies, Pumpkin Space Systems, CU Aerospace, L.L.C., and GomSpace among others.
The demand for cube satellites is significant from various end-users, including military, educational institutions/universities, and commercial entities. The competitive rivalry is high, as the cube satellite industry is complex in nature.
Cube satellites are increasingly used for earth environment prediction, such as earthquake forecasting, climate change, ionosphere monitoring, agriculture, forestry, wildlife, weather forecasting, disaster monitoring, and other applications of earth science. The APAC region is expected to grow at the highest rate during the forecast period in the global cube satellite market.
Despite the challenges, cube satellites are gaining prominence for scientific understanding, low radiations analysis, optical communication, and other scientific applications. However, challenges such as miniaturization, power control, antenna design, delay tolerant networking, and configurations are anticipated to limit their usage.
In conclusion, while cube satellites promise a future of affordable and versatile space access, addressing the hardware design challenges related to thermal control, power management, and onboard systems is vital for sustaining and accelerating global CubeSat market expansion as missions become more complex and diverse.

Cube satellites' hardware design, particularly in thermal management, electrical power systems, and on-board computing, face significant challenges due to the harsh conditions of space. These challenges, such as regulating waste heat in electronics and optimizing power usage, necessitate the development of innovative thermal and power technologies ([1], [2], [3]).
In the global cube satellite market, the competitive rivalry is high among key players like AAC Clyde Space, Planet Labs, and GomSpace ([4]). However, limiting factors like miniaturization, power control, antenna design, and configurations may hinder the expansion of the market for earth science and other scientific applications.
