Coarse Sun Sensor

Overview

The Coarse Sun Sensor (CSS) Pyramid is a 2 axis sensor containing  four  detectors,  used for applications including solar array pointing, sun acquisition, and failsafe recovery.

Over 1,000 Adcole Analog Sun Sensors have been deployed on hundreds of spacecraft since the 1960s. Analog Sun Sensors provide a very large field of view with less accuracy than Adcole’s Digital Sun Sensors.

Adcole Space is able to design baffles to accommodate nearly any unique Field of View (FOV) requirements your mission requires.
