What Does TOS Stand For?

TOS stands for Transfer Orbit Stage

TOS, or Transfer Orbit Stage, is a propulsion module designed to facilitate the transition of spacecraft from one orbital trajectory to another. Typically used in multi-stage launch vehicles, the TOS provides the necessary thrust to move payloads from a lower orbit into a higher, more stable orbit or to escape velocity. This stage is critical for optimizing the efficiency and effectiveness of space missions, enabling precise orbital insertions and increasing payload capacity.
