Study on Non-time Base Cross Circular Position Method for Loran-C
Abstract：With the analysis of the principle of non-time base cross circular position method for Loran-C,algorithm of the position method is derived in detail.After that,position comparisons between single chains hyperbolic position algorithm and non-time base cross circular position method are analyzed with the measured time-difference from the experiments.The results show that position of cross circular position method is close to that of single chain hyperbolic position algorithm when the geometry dilution of precision（GDOP） is good,but with the deterioration of GDOP,position precision can be improved obviously with non-time base cross circular position method adopted,and with the method,the singularity problem of single chain hyperbolic position algorithm when the anchor point is along the baseline can be solved effectively.
