The ~572kg sat ellites are equipped with Hall-effect thruster technology for propulsion. They feature improved systems and sub-systems on board\, including phased array antennas\, processors\, solar arrays\, propulsion systems\, and opti cal inter-satellite links. In addition\, the satellites are coated in a di electric mirror film unique to Kuiper that scatters reflected sunlight to help make them less visible to ground-based astronomers. Kuiper is planned to work in concert with Amazon's network of 12 satellite ground station f acilities. In addition to connecting to ground stations\, satellites will interconnect via optical infrared laser connections. Amazon refers to this technology as OISL (optical inter-satellite link).\nThe Kuiper constellat ion is planned to consist of 3236 satellites operating in 98 orbital plan es in three orbital shells\, one each at 590km\, 610km and 630km orbital altitude.
