About
The PureLine Topaz/THORs subsystem offers an end-to-end solution for satellite electric propulsion, presented in Airbus’s most compact, innovative, and flexible design to date. It is specifically tailored for New Space types of applications, featuring a lifetime of 10 years in Low Earth Orbit (LEO). The unit incorporates latch-up-free parts and error protection, ensuring reliability and robustness. The PureLine series was initially developed for constellation applications, aiming to provide disruptive unit prices while maintaining high-quality products, an approach now extended to global satellite applications. The Topaz/THORs PPU is well-suited for critical orbital maneuvers such as orbit raising, station keeping, and deorbiting.
