只需要按第一个代码块接收GnssMeasurementsEvent参数eventArgs,然后遍历获取GnssMeasurement对象,和GnssClock对象传入构造器,就可以从GnssRawData对象中获取所需的信息。注意GnssClock同一历元是相同的,而GnssMeasurement有多个,如果一颗卫星有多频的观测,会有多个GnssMeasurement对象有相同的prn而carrierFrequencyHz不同。 我的...
Android开发者网站有关卫导RawMeasurement的读取有一大段说明,且提供了GNSSLoggerAPP和相应的MATLAB数据处理程序。但是因为受到手机硬件和系统限制,并不一定能得到相应的数据。 2 界面说明 程序打开后不直接开启数据采集,点击开关可以开启数据采集服务,如果选择保存数据就会将各种数据以时间命名,并保存在Android/data/com....
