中文摘要：

介绍了利用北斗三频伪距和相位组合探测周跳的原理,给出了一种周跳探测的新方法。研究了多频载波相位组合观测量的选取标准,并利用北斗卫星实测数据进行了仿真试验。结果表明：三频观测量可构造出更多组合特性良好的周跳探测检验量,对于单一频点或多个频点同时发生周跳的情况均可有效探测。

英文摘要：

The principle for cycle slip detection with Beidou’s triple-frequency observation data was introduced and a new method for cycle slip detection was given.Selection criteria about combination of triple frequency carries and pseudo-range was discussed,and an experiment was made using real triple-frequency data of Beidou.The result showed more excellent combinations of data may be got using triple-frequency data,the cycle slip of single frequency or multi-frequencies can be detected efficiently with the method.
