Target Location Accuracy analysis without ground control point
2013
The present invention discloses a method of analyzing a target location accuracy without ground control point, comprising: step 1, the actual situation for satellites in orbit, the analysis error sources influence the accuracy of target location; and Step 2, were established for each error propagation model error sources ; step 3, affect the value of the integrated individual sources of error, calculated positioning accuracy satellites target; target location accuracy analysis without ground control points provided by the invention, combined satellite analysis of various factors on the targeting accuracy orbit actual , the analysis affect the actual respective factors positioning accuracy of the target imaging surface, calculate various factors on the targeting accuracy of satellites in orbit size, and transfer model by establishing an error, re-positioning integrated calculation image based on the various factors affecting the value accuracy can be used as reference for theoretical analysis.
