EnduroSat, Sofia, Bulgaria
Nanosatellite manufacturing
EnduroSat is a nanosatellite manufacturer based in Sofia, Bulgaria. The company was founded in 2015 as a start-up with 5 employees and within a short period of time it has grown to a team of over 100 people.
Nanosatellites consist of several cubesat modules depending on the requirements and are sent into space for different purposes of data acquisition.
To improve the processes and quality of the nanosatellites, EnduroSat decided to install a cleanroom in its own office building. This also enables internal testing capabilities that previously had to be outsourced.
Cleanroom production environment improves quality and processes
On their way into space alone, countless forces act on rockets and nanosatellites. This fact makes it even more important to ensure the quality of the nanosatellites for data acquisition and to avoid any contamination of the lenses and other components by dust grains. Manufacturing the nanosatellites in a cleanroom creates the best conditions for this. Filter Fan Units create ISO5 class cleanroom environments at the workstations in an ISO7 environment.
Special design on customer request
To meet the customer's design requirements, the cleanroom was designed in various shades of gray with a white ceiling. A special highlight, a blue airlock device matching the EnduroSat logo.
