摘要

摘要在下一代中，将在工程应用中广泛应用的双频嵌入式GNSS芯片组首次在小米Mi8中使用。考虑到这一发展动态，在土耳其Oyak港用测地GNSS接收器和安卓智能手机对海洋环境监测进行了运动学测试。根据测试结果，水平坐标分量的RMSE为0.0423 m和5.9493 m分别用于大地测量接收器的参考解和PPP-AR解，以及智能手机的参考解与PPP解。此外，单个历元的位置误差计算为0.0411 m和4.6871 m关于给定的次序。采用PPP方法从小米Mi8原始GNSS数据中获得的解决方案为水文测量标准IHO S-44的总水平不确定性（THU）提供了2级。

Precise Point Positioning with GNSS Raw Measurements from an Android Smartphone in Marine Environment Monitoring

Abstract In the next generation, the use of dual-frequency Embedded GNSS Chipset in the smart devices, which will be widely used in engineering applications, has been used for the first time in Xiaomi Mi8. Considering this development dynamics, a kinematic test was carried out in the marine environment monitoring with a geodetic GNSS receiver and an android smartphone in Turkey Oyak Port. According to the results of the test, RMSE for horizontal coordinate components were found as 0.0423 m and 5.9493 m for reference solution and PPP-AR solution of geodetic receiver, and reference solution and PPP solution of smartphone, respectively. Moreover, the positional errors of individual epochs were computed as 0.0411 m and 4.6871 m with respect to given order. The solution obtained from Xiaomi Mi8 raw GNSS data with PPP approach provides the Order 2 for hydrographic survey standards IHO S-44 in terms of Total Horizontal Uncertainty (THU).
