This repository contains the public available design files for the DSS sun sensor designed for the Foresail-1 Cubesat.
The performance and testing of this sensor has been documented in this article.
The general characteristics of sensor design are:
- Dimensions: 20.4 mm × 24.8 mm × 7 mm
- Mass: 4.4 grams
- Panel mountedable into 14x14 mm hole with two M2 screws.
- Electrical connection by soldering on the panel PCB or by harness.
- FOV: ~30 degrees, resolution: 0.027°, accuracy: ±0.008°
- Refresh rate up to 38 Hz. (Sampling time: 15 ms + communication overhead)
- Can provide following data products:
- Raw current measurements
- Point & intensity measurements
- Sun vector & intensity measurements
- Angles & intensity measurements
- I2C digital serial interface (hardware version 4)
- RS-485 digital interface (hardware version 5)
- Low power consumption < 4 mW when active
- Nominal operating voltage: 3.6 - 3.8V: Can be extened easily to 2.0 – 5.5 V.
