AmmoniX: Low-Cost SmallSat End-of-Life Management Deorbiting Stage

nou Systems Inc. (nSI), has developed a revolutionary new modular propulsion concept for SmallSats with exceptionally low SWaP-C and uncompromising performance. These developments represent a pivotal advancement in space propulsion technology and will revolutionize SmallSat end-of-life management. Our system is a compact, lightweight, and modular, propulsion system that is readily integrated with most SmallSat architectures. When a SmallSat reaches its end of life, it activates to provide rapid and reliable deorbiting. Our system is useable at far higher orbits than passive deorbiting technologies (such as drag sails) and its architecture stands out for unparalleled simplicity, high ISP, sustainability, ease of storage and handling, low cost, and operational efficiency. With a significant portion of SmallSats lacking dedicated propulsion capabilities, our technology fills a critical gap, offering a simple, low-cost, and low-SWaP solution for meeting end-of-life disposal policies without contributing to additional space debris, all while using a low-cost green propellant. Phase I will include trade studies, analysis, and laboratory testing. Phase II will proceed with prototype assembly and testing at prototypical conditions laying the foundation for an airborne prototype unit to be demonstrated in Phase III.
