We have succeeded in these investigations, but have also been lucky enough to acquire images like these.”ĮSA supported the manufacturing, assembly and testing of TRISAT-R through the ‘Fly’ element of its General Support Technology Program, opening up in-orbit demonstration opportunities for European companies. “Our main interest has been in capturing examples of the ‘Black Sun effect’ – commonplace in terrestrial digital imaging, where over-saturation of pixels can cause very bright areas to appear dark. Kramberger adds: “The resulting picture of Earth is very low resolution as these highly miniaturized cameras were not intended to perform terrestrial imaging, plus TRISAT-R satellite employs magnetorquers for its attitude control, so that precision pointing is difficult to achieve. In addition, the TRISAT-R team embarked a pair of tiny cameras, with lenses made from clear borosilicate glass to provide limited radiation resistance, mounted directly onto 320×320 pixel image sensors.ĭr. This allows TRISAT-R to test a suite of radiation-detection payloads.

The lens is made from clear borosilicate glass providing radiation resistance, and is directly mounted on the image sensor below providing 320×320 pixels. In the center of the camera you can see the 2 by 2 mm lens of the camera, possessing a 120 degree field of view. The side cover of the TRISAT-R CubeSat measuring 10×10 cm and in the middle can be seen its photo diode (the white component in the middle) and the camera (the small black dot adjacent to the diode, directly towards the top of the image).
