Abstract: A method comprises operating a remote sensing vehicle comprising a host bus platform and a variable pitch instrument platform movably coupled to the host bus platform in at least one degree of freedom. The method comprises establishing a pointing position and scanning a target surface with the variable pitch instrument platform. The variable pitch instrument platform is dynamically movable relative to the host bus platform to vary the pointing position of the variable pitch instrument platform, thereby decoupling payload pointing from the host bus platform. Thus, payload data collection is independent of attitude control of the host bus platform. A method is provided of varying ground-sample-distance (GSD) value with a remote sensing vehicle. A remote sensing vehicle comprises a host bus platform and a variable pitch instrument platform for scanning or data collection of a target surface, and an dynamic coupling device (e.g., a gimbal(s)) movably coupling the variable pitch instrument platform to the host bus platform in at least one degree of freedom.

Abstract: A calibration system for calibrating a tilt angle of the fast steering mirror includes a position sensing device configured to generate a beam of electromagnetic radiation, and a diffractive optical element, positioned between the position sensing device and the fast steering mirror, the diffractive optical element being configured to divide the input beam into a plurality of output beams directed to the fast steering mirror. The position sensing device is configured to determine a tilt angle of the fast steering mirror. A method to calibrate a tilt angle of the fast steering mirror is further disclosed.
