Small satellite constellation deployments in low Earth orbit increased because broadband connectivity requires and Earth observation capabilities together with Internet of Things (IoT) applications. Different propulsion systems need to be developed to fulfill the requirements of orbit raising missions as well as station-keeping and deorbit requirements. Commercial space operators including SpaceX alongside OneWeb and Amazon’s Kuiper group accelerate satellite mission needs through their rising launches which drives researchers to focus on developing efficient compact propulsion technologies for cost-effective high-frequency satellite operations.

Electric Propulsion Systems Gaining Momentum in Spacecraft Design: Electric propulsion systems have recently gained popularity because they both reach high efficiency levels and minimize the need for fuel primarily in satellites and deep-space launches. The systems deliver extended operation times and economical orbital movement abilities that correspond to increased industrial demands for eco-friendly and expandable satellite operations in both military and commercial applications.

North America leads the global Satellite Propulsion System Market, underpinned by strong institutional support, advanced R&D capabilities, and a flourishing private space sector. The U.S. remains the largest contributor with robust funding from NASA and DoD, supporting both chemical and electric propulsion. The presence of private giants like SpaceX and Boeing ensures constant propulsion tech upgrades. Canada and Mexico are actively enhancing capabilities through strategic partnerships and national space programs. The region's continued emphasis on LEO mega-constellations, satellite servicing, and space security sustains high propulsion demand across commercial and defense sectors.
