 Sun Sensor
SSTLs 2-axis sun sensor is based on heritage designs stretching back to 1990 and has over 70 orbit years of flight experience. 
 
Each sensor head consists of an azimuth and elevation slit, and senses the position of the sun in two axes, with a field of view of ±50° in each axis and an accuracy of 1°.

  • Mass : <0.21 kg
  • Power consumption: <100 mW
  • Dimensions : 95 mm x 107 mm x 35 mm
  • Design lifetime (LEO): 7+ Years
  • Operating temperature range: -40º C  to +80º C 
  • Non-operating temperature range:  -50º C  to +90º C 
  • Data interfaces : Analog inputs/outputs
