摘要

摘要: Android系统开放了全球卫星导航系统(GNSS)原始数据观测值,开发人员可以直接通过应用程序编程接口(API)获取GNSS原始观测数据．本文选取小米8和华为P30手机作为研究对象,对手机输出的原始GNSS观测数据进行研究,从多路径效应、数据载噪比方面分析数据质量．实验结果表明:相对于测量型接收机,安卓智能手机的原始观测值载噪比较低且多路径效应严重.

Abstract: The GNSS raw data observations are open for the Android system, and developers can directly obtain the GNSS raw observations through the API. In this paper, Xiaomi Mi 8 and Huawei P30 mobile phones are selected as the research objects. The original GNSS observation data output by the mobile phone is studied, and the data quality is analyzed from the aspects of multipath effects, data carrier-to-noise ratio. The experimental results show that compared with the measurement receiver, the original observation value of the Android smartphone is relatively low, and has serious multipath effect.
