gnssrefl是GNSS interferometric reflectometry（GNSS-IR）python软件包。 支撑 终端命令行 （bash） 和 导入库（import xxx） 两种工作方式，包括三个主要的模块。 rinex2snr：将RINEX文件转换为分析所需的SNR文件；gnssir：根据SNR文件计算有效高度（reflector heights，RH）；quickLook：提供一个快速可视化评估（图片），而不需要处理与gnssir相关的细节，它不能用于日常分析，但是可以帮助你选择合适的方位角范围和质量 控制参数。 除此之 …

Permanent GNSS receivers are instruments that receive signals from Global Navigation Satellite Systems (GNSS), such as GPS, GLONASS, Galileo and BeiDou, and use them to position the receiver in space and time.

2018年6月16日 · GNSS-R interferometric reflectometry (also known as GNSS-IR, or GPS-IR for GPS signals) is a technique that uses data from geodetic-quality GNSS instruments for sensing the near-field environment. In contrast to positioning, atmospheric, and timing applications of GNSS, GNSS-IR uses the signal-to-noise ratio (SNR) data.

This portal contains water level data extracted from permanent GNSS receivers using interferometric reflectometry. What is GNSS-IR? A brief explanation. What steps did we take to create these files?

GNSS-IR measures the vertical distance (or reflector height RH) between the GNSS antenna phase center and the horizontal surface (snow, water, soil moisture, soil) below the antenna. If you are familiar with the method and want to try out the technique at different places, choose one of the sites in examples above.

2021年11月25日 · The software developed, named GIRAS (GNSS-IR Analysis Software), can process multi-constellation GNSS signal data and estimate the SNR metrics, namely phase, amplitude, and frequency, for further computations with several optional statistical analyses for controlling the quality of the estimations, as required, such as snow depth retrieval ...
