Key highlights

Dawn Aerospace provides custom propellant tank options as part of their turn-key SatDrive product line. Instead of standardizing the tank, they have standardized the product development, applying standard and proven methods from design to manufacturing and qualification to achieve your custom propulsion needs.

Tanks are simple and lightweight, with no external helium pressurization devices, high-pressure regulators, mechanical PMDs, or moving parts. They are produced using additive manufacturing, enabling extreme customization in software with minimal downstream bespoke tooling required, dramatically reducing NRE costs and lead times.

Key features
