In the field of spaceborne remote sensing, a geometric collinearity equation of pushbroom sensor with the Kepler parameters of the satellite orbit and the attitudes of sensor has been developed. Testing the sensor model on a SPOT-5 imagery, the planimetric accuracy of object positioning is 83.392m on the ground. According to the orbital dynamical model and the kinematics model of satellite attitude, an algorithm of extrapolative location is developed. Testing the algorithm on CBERS-2 high resolution satellite imageries of central China, when the depth of extrapolation is 300km, the planimetric precision is 53.555m including the measurement errors as well as the modeling error over than the 568m which is the planimetric precision of systematic rectification.
