TopSat Follow-on Concepts

• TopSat Plus: Similar resolution to TopSat demonstrator; greater imaging size, capacity, accuracy & greater lifetime

• TopSat Enhanced: Pushing towards limit of current camera design, and lowering altitude to achieve 1.65m resolution (pan).

• TopSat One Metre: Aspiration to achieve 1m resolution with low cost spacecraft – subject to developments in lightweight optics and structures

• Low costs supports constellations to give high timeliness
