GPS历元比较时间对齐方法

基于“齿轮转动”思想，本文设计了对GPS历元时间对齐比较的方法，实现了两个GPS历元文件各历元准确遍历自动查询，有效解决了历元比较时间对齐耗时、费力问题；通过文件两两比较可实现三文件比较，该方法查询速度快、省时简便，同时为其他具有相同特性的数据比较提供了很好的经验，具有较好的实际应用价值。

Time-aligned Method of GPS Epoch Comparison

Based on the idea of ＂gear rotation＂, we design the method of time aligmnent of the GPS epoch comparison. According to GPS time it can autnmately itermale and query the GPS epoch in two files. The method not only can effectivly solve the time-aligned problem of lime-consuming, laborious and so on, but also through pairwise comparison can achieve time-aligned in three files. Using this method can queries lastly, simply, time-saving, whose experience can be used in other data with the same characteristics. So, it has good practical application .
