he MAUS fulfils the wishes for a small but reliable Sunsensor that can be easily accommodated on board of a CubeSat. Although the MAUS does not have the highest functionality of all CubeSat sun sensors, the guaranteed accuracy, high radiation tolerance and Lens R&D reputation for quality have been important for this development.
The MAUS is the only known radiation hardened Cubesat Sunsensor know to be commercially available and the bare diodes have been acceptance tested to 8E14 1MeV electrons (equivalent to 19.2Mrad TID and 25E9 MeV/g TNID).
The 0.65mm Sapphire window provides 1mm Aluminium equivalent radiation shielding leading to a sensor that can be used on any Cubesat mission known without even coming near to the radiation withstanding capabilities.
The sensors have sustained a full ECSS qualification as defined in ECSS-E-ST-10-03
Lifecycle thermal vacuum cycling consisting of 1000 TVAC cycles between -45°C and +85°C followed by another 1000 cycles -45°C and +105°C have been completed. This accelerated life test program is equivalent to 27400 cycles over the specified -40°C..+80°C temperature range)
Developed on customer request tens of these sensors are already flying on multiple satellites as core Sunsensor for the ISISpace Cubesats. (among which the KLEOS satellite clusters)
