About
The SPS-25 Propulsion System is engineered for small satellites with a mass of up to 500 kg. Its primary functions include adjusting the satellite’s position in orbit and facilitating deorbiting at the end of its operational lifespan. Key advantages of this propulsion system are its low mass, which is crucial for small satellite missions, and its fast production capabilities, allowing for quicker deployment and scalability. The system is a complete propulsion solution, not just a thruster, and is intended for integration into satellite platforms requiring precise orbital control and end-of-life disposal.
