| 摘 要： | 针对不同长度的基线,受双差之后电离层延迟影响不同,提出一种新的电离层处理策略。对短、中、长基线处理分别采用3种不同的数学模型:电离层固定模型,电离层加权模型,电离层浮点模型。通过3组不同长度基线实测数据处理表明,对应不同长度的基线,文中策略可以有效地提高模糊度固定率及定位精度。

| Abstract: | As to different‐lengths baseline ,differently affected by double‐difference ionosphere delay ,a new treatment strategy of ionosphere is proposed . Three different mathematical models are used for short , medium and long baseline :ionosphere‐fixed model , ionosphere‐weighted model and ionosphere‐float model .The three different‐lengths baseline data measured show that :this strategy can improve the ambiguity‐fixed rate and positioning accuracy for different‐lengths baseline . |
