en.Wedoany.com Reported - Since its founding in 2009, Spanish space technology company Solar MEMS Technologies has focused on MEMS-based sun sensors, star trackers, and high-precision attitude determination solutions for space and defense applications. Its product portfolio, centered on high-performance sun sensors and star trackers, provides critical orientation data for spacecraft Attitude Determination and Control Systems (ADCS). Designed for CubeSats, NanoSats, MicroSats, scientific missions, Earth observation platforms, and defense-related spacecraft, these sensors support satellite orientation, navigation, and control functions.
In the field of sun sensors, Solar MEMS offers products such as the Advanced Coarse Sun Sensor (ACSS) and the high-performance digital sun sensor DSS-BR, providing high-precision angular measurements. Combined with real-time data acquisition, onboard processing, and advanced calibration methods, these sensors deliver reliable attitude information during spacecraft operations. The company also features the S2S series of sun sensors, specifically designed for high-accuracy sun tracking within a compact and lightweight package. These systems support imaging payloads, scientific observations, telecommunications operations, and Earth observation missions. Utilizing Micro-Electromechanical Systems (MEMS) technology, its sun sensors achieve high-precision measurements of the sun's incident angle while maintaining extremely small size, weight, and power consumption. The sensors are designed to withstand harsh orbital environments including radiation exposure, temperature fluctuations, and vacuum conditions, and provide fast sensing performance at low power, making them particularly suitable for small satellites with limited onboard power budgets.
Beyond sun sensors, Solar MEMS has developed compact star tracker systems designed for advanced spacecraft navigation. Star trackers determine spacecraft attitude with extremely high precision by capturing images of star fields and comparing them with onboard star catalogs. These systems are suitable for small satellite platforms, aligning with the NewSpace industry trend toward miniaturization and enhanced capabilities. The company's products are designed with integration flexibility in mind, allowing spacecraft manufacturers to incorporate them into various satellite architectures without extensive redesign, thereby reducing development complexity and supporting faster mission deployment timelines.
When integrated with systems such as sun sensors, star trackers provide complementary attitude information, enhancing spacecraft pointing accuracy, mission autonomy, and overall navigation performance. These technologies are applied in fields requiring precise attitude control, including Earth observation imaging, scientific missions, communication satellites, technology demonstrations, and defense-oriented space programs. Solar MEMS sensors are also used in sun tracking systems, autonomous vehicles, defense monitoring equipment, and other precision positioning systems requiring accurate orientation sensing, extending the company's technological footprint from space to multiple industries.
Solar MEMS has supplied sensors to government agencies and commercial organizations operating in Europe, Asia, and the Americas, serving a broad international customer base. The company has participated in multiple projects involving the European Space Agency (ESA), focusing on advancing sensor accuracy, calibration methods, radiation tolerance, and operational robustness. The rapid expansion of Low Earth Orbit satellite constellations has increased demand for compact, reliable, and cost-effective attitude determination systems. Through its MEMS-based sun sensors, compact star trackers, and customized sensing solutions, the company continues to support spacecraft orientation, navigation, and mission control in commercial, scientific, civil, and defense applications.
