Understanding environmental change relies on observational technologies that analyze the interaction between electromagnetic radiation and matter. Spectroscopy provides the physical foundation for many sensing techniques used in Earth sciences, operating across the ultraviolet (UV), visible (VIS), and infrared (IR) spectral domains. Technologies such as LiDAR, thermal imaging, photogrammetry, and optical remote sensing rely on these principles to observe environmental processes and monitor changes in the Earth sys...

A decade of improvements and new development of tools for observation statistics, standard point positioning, clock-jumps and cycle-slip detection and other interruptions over all constellations, frequencies and signals, satellite elevations and azimuths, elevation-specific histograms, satellite ascending/descending times for horizon and user elevation cut-off, pseudo-range multipath and noise, carrier-phase signal-to-noise ratio, data gaps and small data pieces and other useful lists and statistics allow us to an...
