Feature List
The CubeSense module is an integrated sun and nadirsensor for attitude sensing. It makes use of two CMOScameras - one dedicated to sun sensing and another forhorizon detection. The sun sensor has a neutral densityfilter included in the optics. Both cameras have wide FOVoptics. The primary outputs of the sensor are two anglesthat can be used to calculate the sun and nadir vectorsrelative to the CubeSense camera boresights.
Cameras:1024 x 1024 pixel CMOS image sensorFisheye lens, 150o effective FOVConfigurable placement options for each camera
Onboard:Processing of nadir and sun centroids done onboardDual FPGA/SRAM system for redundancyMeasurement updates @ 1 HzI2C and UART interfaces available
