Fine Sun Sensor
TensorFSS-15M fine sun sensor is a satellite attitude determination system based on an advanced photodiode quadrant detector shielded by an aperture mask. This design ensures sun incidence measurements up to 0.1-degree accuracy. Equipped with an embedded error correction table—derived from thorough in-house calibration—TensorFSS-15M delivers top class performance while remaining affordable for all budgets. Consuming 5.5 mA at 16 Hz and compliant with GEVS and ECSS testing standards, TensorFSS-15M combines reliability and efficiency. Additionally, its compact design ensures easy integration into satellite systems, making it an indispensable asset for a wide range of satellite applications.
Features
2-axis digital fine sun sensor

Lower Power Consumption
Robust and Autonomous Recovery Mechanism
RS485 Interface
Calibration with automated rotary table
TensorFSS-15M offers configurable magnetometer functionality, which can be enabled or disabled based on mission requirements. When the magnetometer function is enabled, it enhances the measurement accuracy and reliability by providing additional magnetic field data to complement sun vector readings.
This dual-source sensing enables improved attitude determination, especially in scenarios where sun visibility is limited or environmental conditions introduce uncertainty. To ensure accurate magnetometer performance, TensorFSS-15M with magnetometer functionality should be installed at least 10 cm away from potential sources of magnetic interference, such as Control Moment Gyroscopes (CMGs), motors, or high-current wiring.
Enabling the magnetometer function transforms TensorFSS-15M into a more versatile and robust sensor, capable of supporting higher-precision orientation awareness for satellite missions.
