【Abstract】 Based on the three-dimensional coordinate conversion system on the elliptical earth reference model,a positioning scheme is proposed depending on the airborne receiver data of a ground object with the azimuth of the object relative to the receiver and the distance between the receiver and the object,while the elevation angle measurements relative to the receiver are not used.The scheme can be used in electronic map.The effect of errors of the scheme and the measuring data on the positioning precision is analysed.The scheme is proved to be feasible by simulation.更多还原
