SATELLIITE CAMERA

The highly reliable optical payload, for capturing high-resolution images from the ground surface and atmospheric phenomena. The s.LDU.345 has been designed to be implementable in a standard 6U CubeSat structure together with other subsystems to allow low – cost Earth observaton.
