    Abstract
    The concept of a storable liquid monopropellant blend for space applications based on Ammonium Dinitramide (ADN) was invented in 1997. The objective was to develop a propellant which has better performance and is safer than hydrazine. The work has been performed under contract from the Swedish National Space Board and ESA. The progress of the development has been presented in several papers since 2000.
ECAPS, a subsidiary of the Swedish Space Corporation was established in 2000 with the aim to develop and market the novel “High Performance Green Propellant” (HPGP) technology for space applications. The new technology is based several innovations and patents w.r.t. propellant formulation and thruster design, including a high temperature resistant catalyst and thrust chamber. 
The first flight demonstration of the HPGP propulsion system will be performed on PRISMA. PRISMA is an international technology demonstration program with Swedish Space Corporation as the Prime Contractor. 
The PRISMA mission includes two satellites in LEO orbit were the focus is on rendezvous and formation flying. One of the satellites will act as a “target” and the main spacecraft performs rendezvous and formation flying maneuvers, were the ECAPS HPGP propulsion system provides delta-V capability. 
This paper describes the performance, design, characteristics and verification of the HPGP propulsion system for PRISMA. Compatibility issues related to using a new propellant with COTS components is also discussed. 
The PRISMA CDR was held in January, 2007. Integration of the flight propulsion system has started.
The flight opportunity on PRISMA represents a unique opportunity to demonstrate the HPGP propulsion system in space, and thus take a significant step to towards its use in future space applications. The launch of PRISMA scheduled to 2009.
