LC29D模组支持双频段GNSS原始观测量数据输出和IMU原始数据输出，结合RTK技术和DR，可实现亚米级最高厘米级定位精度。L26-P模组支持多星座卫星信号并发接收，并集成6轴传感器，可输出GNSS raw data和 IMU 数据，在开阔环境下可实现厘米级定位精度（算法运行在 HOST 端）。移远通信GNSS定位模组新品 在本次研讨会上，...
In this paper, we propose a method to improve the positioning accuracy in urban areas by integrating raw data from satellites with sensors installed in smartphones through the Kalman filter and the Gaussian sum filter. Experimental results by these filters are compared, and it is shown that the...
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...
