This infrared all-sky monitor uses an InGaAs camera sensor at 1550nm to provide real-time, hemispherical intensity monitoring without requiring active satellite tracking. It helps distinguish between signal degradation caused by atmospheric turbulence, aerosols, or pointing errors in optical downlinks. This metrology tool effectively reduces ambiguity in failure diagnosis for ground station link verification.
