About Solar MEMS Technologies

Solar MEMS Technologies (SMT) is a space hardware company based in Seville, Spain, specializing in MEMS-based attitude determination sensors for small satellites. Founded within the Parque Aeroespacial de Andalucía Aerópolis aerospace park, SMT develops and manufactures coarse and fine sun sensors, star trackers and horizon sensors that are flight-proven across hundreds of delivered units.

SMT's product line covers the full range of attitude sensing needs for CubeSats, nanosatellites and microsatellites: from simple analog coarse sun sensors (ACSS, nanoSSOC A60) to digital fine sun sensors (SSOC D60, nanoSSOC D60) and complete star tracker systems (nanoST, MicroST). The company's CSS technology has flight heritage since 2019 and the manufacturing process has been developed and industrialized for mass production.

The company holds ISO quality certification and its products are qualified to ECSS standards. SMT's sensors have been selected for a broad range of LEO, MEO and GEO missions by customers in Europe and worldwide. Product lines include radiation-hardened variants (ACSS RH) for demanding orbits and a horizon sensor (HSNS) for nadir vector determination.

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
