MAUS (drw-nr: 114T000)


The MAUS is a  radiation hardened (>10Mrad) fine sun sensor especially developed for the CubeSat market. Taking advantage of the BiSon64-ET developments while keeping a focus on the special requirements for the smallest satellites, the MAUS is combining high reliability Sun sensing with a very low profile.

he MAUS fulfils the wishes for a small but reliable sun sensor 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).

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.

Vibration testing has been completed

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..+105°C temperature range)

The first sensors are expected to be launched with a Falcon heavy launch in June 2021 after several months of delays but these sensors (15 in total on 5 separate satellites) will provide a solid TRL9 status without skipping the TRL8 step.
