The Tensor Tech CSS-10 is a coarse sun sensor that is suitable for spacecraft with low pointing requirements or needs a robust input for the sun-acquisition algorithm.

The product has a simple and robust design. The CSS-10 outputs analog signals that are proportional to the solar irradiance.

Multiple sun sensors are recommended to be installed on different faces of the satellite to maximize the field of view of the sun sensor array.

The user has to prepare analog-to-digital converters (ADC) for the onboard computer (OBC) or the ADCS computer to access the data from each CSS-10.

The more CSS-10 is used, the more channels the user has to prepare for the ADC.

Key features

  • Analog-type coarse sun sensor
  • Hardware protection for short-circuit-caused system failure prevention
  • Six coarse sun sensors can provide a full sky (4π) FOV coverage (± 60 deg for each sensor)
  • 1-axis analog coarse sun sensor
  • <5 deg (1-sigma) of sun determination accuracy is achievable following the user manual’s calibration instructions
  • Hardware protection for short-circuit-caused system failure prevention
  • An analog-to-digital converter should be installed to extract information
  • Three pins including Vcc, GND, and output line.
