About
The Tensor Tech FSS-15 is a compact and cost-effective fine sun sensor designed for mass production with stable quality. It incorporates an embedded microcontroller that utilizes an error table for tabulated correction, allowing users to directly access sun angles via digital interfaces such as I2C and UART. Each FSS-15 unit is shipped with a unique, pre-measured error table. The sensor is capable of detecting and recovering from radiation-caused transient errors through its embedded firmware. It offers a pointing error of 0.1 degrees (1 sigma) and has a field of view of ±60 degrees, with optimal performance at 45 degrees. The sampling rate is user-adjustable at 2, 4, 8, and 16 Hz. It boasts low power consumption, less than 2 mA during sampling and under 0.5 mA at idle. The FSS-15 is mechanically small, measuring 22.00 x 15.00 x 5.26 mm and weighing less than 4g. It also features radiation tolerance exceeding 10 krad. Tensor Tech also offers a coarse sun sensor, the CSS-10, for less stringent performance requirements. The FSS-15 has flight heritage since 2022.
