To verify the feasibility of the geolocation of space camera by the whisk broom imaging,the geometric model of space camera by whisk broom imaging was built concerning the change of the image scale,the whisk angle measurement accuracy,the whisk angle stability and the whisk angular velocity,taking the factors of geolocation accuracy in the overall design as the parameters.The geolocation accuracy algorithm based on the error propagation theory was derived,the simulation was carried out and the improving met...
