Infrared (IR) Earth Horizon Sensor
Price on request
CubeSense Earth is a compact and reliable infrared earth horizon sensor that provides high-accuracy nadir determination throughout the entire orbit. This allows for accurate satellite control in eclipse without the need for a star tracker, making it a less expensive alternative. Each CubeSense Earth is verified with our infrared lens calibration and earth emulator jig, which is an innovative in-house test set-up designed and built by CubeSpace (CS) engineers.
