日本版GPS蓄势待发
日本版 GPS 定位卫星 卫星系统
2017/5/19
卫星定位是物联网、大数据等相关产业的基础，各国竞相竞争。同时，其在宇宙开发应用中也处于先导地位。日本版GPS正在加紧实施，日本内阁府最近公开了准天顶卫星系统“引路”第2号定位卫星。日本计划2017年秋天，用国产火箭“H2A”发射2号机等三颗定位卫星，加上以前发射运行的1号机，从2018年度开始将共有四颗定位卫星运行。离正式运行仅剩1年的日本版GPS试图超越美国及欧洲，开创日本自主的新业态。
针对GPS载波相位定位技术中的周跳问题,提出了一种改进的组合周跳探测与修复方法。电离层残差法很好地适用于双频动态数据的周跳探测,但是该方法不能判断周跳发生在哪个载波相位,同时当两个频率发生特殊的周跳组合时,该方法不能探测出周跳。因此采用载波相位线性拟合方法进行辅助探测,通过对周跳历元附近前6个历元载波相位观测值进行线性拟合,估算出周跳历元的载波相位估值,并与实测值作差,如果差值超出限差值,则认为发...
