摘要
通过多频载波相位组合观测值的长波长特性,结合传统的伪距/载波探测原理,利用模拟的GPS多频数据进行了各种情况下周跳与粗差的探测及修复,同时对一条GPS基线进行了原始观测数据预处理的实例分析.结果表明,通过多频数据组合能够完全实时修复大采样率条件下各种情况的周跳,可以实时探测出0.2周以上的粗差.
Used stimulant multi-frequency carrier data to detect and repair cycle slips and gross error in different conditions, utilizing the traits of some long wave combinations with the principle of traditional pseudo-range/carrier phase combination. Through the example which made a preprocessing of original carrier phase observation in a GPS baseline, the result indicates that we can repair multifarious real-time cycle slips completely and detect real-time gross error up to 0.2 cycle.
