Abstract：The relative positions and spatial attitudes of transmitters in Indoor GPS industry measurement system should be calibrated before the measurement being carried on. A single cylindrical sensor will be adopted combining a scale bar to obtain the azimuths and elevations of the transmitters at different spatial points in order to carry on the self-calibration. The transforming model of coordinate parameters based azimuth and elevation angles are established and calculated through least square algorithm of non-linear optimization to accomplish the self-calibration. Experiment testing shows that this calibration method is convenient and feasible.
