FDSS of Solar MEMS is a very accurate sun sensor immune to Earth albedo and any other unexpected albedo source. This sensor captures images of the Sun in less than one millisecond and identify the Sun and any other light source, allowing to collect extra information like albedo vector.

Its robustness is based on highly used COTS devices together with space grade parts, and it is plug & play, so it does not need any additional electronic support or module for operating.
