Bradford ECAPS
aka ECAPS, Bradford Space, ECAPS AB
Bradford ECAPS (Ecological Advanced Propulsion Systems) is a Swedish green propulsion company founded in 2000, operating under the Bradford Space group (Netherlands-based). The company invented High-Performance Green Propulsion (HPGP) using the ADN-based propellant LMP-103S, which offers 6% higher specific impulse and 24% higher density than hydrazine, enabling factory fueling. Bradford ECAPS has flight heritage on PRISMA (2010), 13 SkySat satellites, STPSat-5, and Astranis MicroGEO communications satellites.
