The flight heritage for ECAPS' propulsion technology based of Ammonium DiNitramide (ADN), started 2010 with a successful 5 years on orbit demonstration mission of the PRISMA satellite. Since 2016, launches of satellites from 3 different continents continues to add to the flight heritage. Thirteen SkySat earth observation satellites with ADN-based propulsion have added more than 28 years of accumulated flight heritage for LMP-103S and ECAPS' 1 N HPGP thrusters.
