A Troposphere Tomography Method by Combining the Truncation Coefficient and Variance Component Analyilization rate of GNSS observation but also leads to a low percentage of voxels crossed by rays. In order to overcome this issue, the GNSS signals penetrating from the model’s side face are also used to build the observation equation by introducing the truncation coefficient in this paper. Due to th

Research on Smoothing Filtering Algorithm of BDS/GPS Slow Deformation Monitoring Sequencee method, a robust moving average method is proposed. An adaptive windowing method is developed and combined with ARMA time series analysis to improve the prediction precision of monitoring sequence. The experimental results show that, the robust moving average method can effectively weaken the erro

A Study of TEC Storm on 13 October 2016GPS stations from 0°E to 360°E. Total electron content (TEC) was calculated with polynomial method, and TEC difference between the storm time and quiet time (ΔTEC) were calculated. The variations of TEC difference were different at different longitudes. There was a positive phase storm at the local

An Alternative Approach for Estimating SNR Metrics in GPS-IRh as soil moisture, snow depth and vegetation parameters. The direct and reflected signals will be mixed by omni-directional geodetic GPS antenna and the interference patterns of the both signals are recorded in signal-to-noise ratio (SNR) data. The SNR metrics, which refer to the phase, amplitude a

Feasibility Study of Low Cost Receiver for Deformation Monitoringthe positioning accuracy ultimately. Therefore, the receiver is sufficiently important for the whole navigation and positioning process. Deformation monitoring belongs to precise engineering survey and it often needs to reach the millimeter-level accuracy, so that the geodetic receiver with excellen
