Space Innovation Solutions SpaceIS aims to revolutionise satellite connectivity via its novel 3Dprinted multibeam antenna Over the next few years it is anticipated that a large number of satellite constellations will be orbiting Earth in nongeosynchronous orbit NGSO providing a wide range of broadband services The key feature that differentiates NGSO from GSO systems is that the ground terminal must track relatively fastmoving satellites as they transverse the visible sky and communication must be handed from one satellite to another SpaceIS can offer seamless satellite handover makebeforebreak with very low cost and efficient SWaP Size Weight and Power Its antenna can bend radio waves through its unique lenses creating beams that communicate with several satellites in different orbits and angles with no moving parts all at the same time
