In the last few decades, the space industry has developed rapidly. In 2024 alone, space companies have launched nearly 15 times more satellites than in the past decade. Today, there are many new types of space systems and satellite constellations around the Earth, the Moon, and beyond. Their deployment, support while in orbit, and other in-space mobility operations are becoming critical factors in making space research and development more rational and sustainable.
One major issue is that space has become increasingly crowded. Beyond this, there are many other challenges to sustainable development, including how to monitor impact, how to increase connectivity, etc. Such ambitious goals demand advanced solutions, an important part of which will be in-space mobility. This is where SETS comes in: we provide our clients with a precise and reliable approach to controlling the movement of satellites.
What Is Driving The Demand For In-Space Mobility?
Space operations have become increasingly complex, especially as more satellite constellations enter orbit. This, in turn, has made the need for in-space mobility more apparent since this can significantly affect the cost and performance of these constellations. Beginning with launch, different types of mobility are crucial for mission success. Rockets put satellites into space, but in-space propulsion systems are needed to ensure mobility throughout a satellite’s lifetime, including reaching the required orbit, maintaining orbit, and deorbiting after its mission has ended. It is thus important to understand the necessary parameters (including satellite lifetime, delta-V, etc.) to choose an in-space mobility approach that best fits the operator’s needs. This is even more crucial for satellite constellations, where precise orbit positioning affects overall performance.
Furthermore, in-space mobility is not just about getting a satellite from one place to another; it is also about ensuring that the satellite works well throughout its mission. Effective mobility systems are key to improving performance, extending the life of space assets, and cutting mission costs.
Let’s take a closer look at some of the most common purposes and implementation scenarios of in-space mobility solutions.
Propulsion Operations
The most important function of in-space mobility systems is spacecraft maneuvering. Without these systems, it would be impossible to adjust satellite positioning, perform orbital maneuvers, or keep satellites running smoothly throughout their lifecycle. Effective in-space propulsion helps reposition satellites, avoid collisions with space debris, and adapt to changing mission needs.
At SETS, we believe that the most important part of in-space mobility is the propulsion system, because it is impossible to move the spacecraft without it. The SETS SPS-100 Propulsion System is a perfect mobility solution for medium and large satellites, especially those in GEO, on deep space missions, or requiring complex orbital maneuvers.
The SPS-100 provides thrust up to 90 mN and uses up to 1600 W of power, helping satellites stay on track and make necessary adjustments throughout their missions. The system includes ST-100 Hall-effect Thrusters, a Xenon storage and feed system, and a Power Processing Unit. Its advanced design and high total impulse (up to 3 MN∙s with one thruster) make it a great choice for numerous tasks, from keeping orbits stable to exploring deep space.
Spacecraft Deorbiting
Another important function of in-space mobility systems is spacecraft deorbiting, or safely removing satellites from their orbits at the end of their missions to prevent space debris. Our SPS-25 Propulsion System is a perfect choice for such tasks. It is well-suited for small satellites weighing up to 500 kg and helps adjust their positions to ensure safe deorbiting.
The SPS-25 can handle both position adjustments during the mission and efficient deorbiting afterward. With a dry mass of only 5 kg (excluding the tank) and a total impulse of up to 115 kN∙s, the SPS-25 provides a lightweight, fast-production solution for the in-space mobility of small satellites.
Commercialization of Space Exploration
Commercial space projects are emerging rapidly, bringing previously unthinkable business strategies, like refueling spacecraft in orbit or mining resources on asteroids, the Moon, and other planets, one step closer to reality. Indeed, ambitious startups are already pushing to complete such projects in the next decade. A reliable and cost-effective propulsion system plays a crucial role in such missions. SETS is well-positioned to be a go-to partner for our clients, providing quality, flexibility, and customization for any need.
SETS Provides Customer-Oriented In-Space Mobility Solutions
With all of these factors to consider, things can get complicated fast. But at SETS, we keep it straightforward: we focus on empowering the customer. We offer both commercial off-the-shelf products as well as tailored solutions, and our team designs electric propulsion systems that can be customized to match your mission’s specific requirements. Whether your project involves maintenance, deorbiting, or performing other maneuvers in space, SETS will ensure that the propulsion system you receive is appropriate to the job.
Our approach is to provide electric propulsion systems that are customized to fit the client’s specific needs. The client determines when to activate the thruster. So, while SETS does not offer a complete “end-to-end” in-space mobility solution, we do provide the means for effective in-space mobility.
This approach provides a big advantage: flexibility. By letting customers control when and for how long propulsion systems will operate, they can adjust to real-time mission needs and make changes as required. This level of customizability is invaluable in space, where every ignition and every maneuver counts.
In addition, in-space mobility is the key to any space mission’s success, and the propulsion system is at the core of it. At SETS, we believe that electric propulsion systems are the most important part of in-space mobility and are essential for the success of any mission. Our products are designed with precision and reliability in mind, ensuring that our clients have the power and control they need to achieve their mission objectives.
