A new optical imaging satellite is being designed for the Maritime Domain Awareness mission. The satellite will be placed in a circular orbit at 5000 km altitude and be able to look off of nadir, giving a maximum range to the target of 7000 km. The desired resolution is 3 meters. Assuming the sensor will operate in the SWIR (λ = 1.5 μm), estimate the required diameter of the primary aperture to achieve the desired resolution at the maximum range. Report answer in meters to two significant digits. The required aperture diameter is _____ meters.
