| Summary | We are using GPS Technology in not only car-navigation but also Intelligent Construction. High Accuracy Positioning makes more efficient for Public Works. RTK-GPS provides cm-ordered accuracy, but it always needs more than 5 Satellites acquisition. This paper describes about how we can get fast initialization for RTK-GPS and high-accuracy under severe condition, such as mountain area. |
