Coarse Sun Sensor Detector

Spacecraft Sun Sensors for
Attitude and Guidance Control

Field of View:        

Approximate cosine, conical symmetry
Note: Baffles can be provided to restrict the Field of View

Input Power:           none

Output Power:         500 µA to 1300 µA peak. Can be customized to program requirements.

Configuration Features:

Single Detector

Coarse Sun Sensor Pyramid Type

The Coarse Sun Sensor Detector is a single detector model used for applications including solar array pointing, sun acquisition, and failsafe recovery.

Field of View:         2π steradian plus

                             (baffles can be provided to restrict

                                        the field of view)

Accuracy:            ± 2° at Null (typical)

Input Power:        None

Output:                 500 µA to 1300 µA peak,                                   each detector


Redundant system:  2 sensors

                                    (with redundant electronics)

Number of measurement axes: 1 (each sensor)

The Pyramid type is an assembly of multiple coarse detectors (custom baffles available)

Coarse Analog Sun Sensor

Field of View:       Measurement Direction

                            Linear Range ±20°
                            Full FOV ±40°
                            Insensitive Direction ±55° Min.


Accuracy:            ±0.75° over the ±20°

                            linear range

Input Power:      None

Output:              300 µA peak for each cell segment

The Adcole Coarse Analog Sun Sensor is a single axis model used for attitude control, solar array pointing, sun acquisition, and failsafe recovery.  Hundreds of these sensors have flown on earth orbiting and interplanetary programs.

​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.
