| 摘 要： | 将遗传算法(GA)应用于GPS双差模糊度解算过程,针对双差模糊度的整数特性,进行了实数编码的改进、遗传算法的改进等算法设计,实现了双差模糊度直接在大范围、高精度、整数域上的优化搜索,提高了解算的稳定性与高效性。试验结果表明,经过改进的实数编码GA可以取得比二进制编码GA更高的效率和成功率,更适于双差模糊度搜索。

| Abstract: | This paper studied the ambiguities resolution of double difference GPS used genetic algorithms(GA).For the integer nature of double difference ambiguity,the algorithm designs,such as the real code improvement,the improvement of genetic algorithm,were conducted.Then the optimization searching of double difference ambiguities was realized in integer fields with wider range and higher accuracy,improving the stability and efficiency of resolution.The test results showed that this proposed algorithm was more suitable to the searching of double difference ambiguities. |
