In order to guarantee quality of operational imagery regular radiometric calibration checks, under both preflight and in-flight environments, are a necessity. While preflight calibration is conducted in the field with relative ease, to conduct in-flight calibration checks during operational missions is difficult, especially when onboard calibration instrumentation is not available. The calibration of MAVS imagery in flight requires a radiative transfer code such as the 6S to simulate the radiation signal at the operational altitude. A comparison of the simulated in-flight calibration equation with the corresponding preflight calibration equation showed a statistically significant agreement for every MAVS band, demonstrating the stability of response of the instrument in the air. This MAVS response stability indicates a potential for calibrating operational airborne imagery using preflight calibration equations. A few simulated in-flight calibration checks, in addition to regular preflight calibrations, could still be carried out during the flight season to verify system radiometric response in the air.
