About Solar MEMS Technologies

Solar MEMS Technologies S.L. was founded in 2009 as a spin-off from the University of Seville, commercializing MEMS (Micro-Electro-Mechanical Systems) technology for space applications. The company develops and manufactures highly miniaturized sun sensors and star trackers that enable precise attitude determination for nanosatellites, microsatellites, and larger spacecraft.

The company offers a broad portfolio ranging from coarse analog sun sensors to high-accuracy digital sun sensors and star trackers. Their products are qualified for space operation and have accumulated significant flight heritage on missions operated by NASA, ESA, JAXA, and CNES. Solar MEMS sensors are particularly popular in the CubeSat and small satellite sector due to their compact form factor, low mass, and low power consumption.

Solar MEMS Technologies is certified under ISO 9001 and follows ECSS standards for space product development. Their customer base spans commercial satellite operators, research institutions, and government space agencies worldwide.

Milestones

  • 2019 CSS sun sensor technology achieves flight heritage; hundreds of flight units delivered
  • 2023 nanoST and MicroST star trackers enter production for nanosatellite and microsatellite missions
