| Abstract: | Because of the needs of high precision radio ranging system,the article designs a low-cost,stored,wireless transmitting GPS reception system based on the virtual instrument technology,the system uses the SDT11 to receive the GPS’s signal,it can deliver the data for long distance by enlarging the frequency,and use the special software to get the distance information.The system can test the distance longer the 7km,precision smaller the 15m,it solve the problem of high precision in long distance testing.According to the other ranging system,the Double-GPS Ranging System have the advantage of long distance,high precision,low cost,good timing,low interfering by the weather,so the system has amplitude market foreground. |
