Geoid or GNSS processing method? What determines the accurate determination of mountain peak heights?

24-02-2026

The height of mountain peaks can be determined using precise GNSS measurements. However, it should be remembered that GNSS gives the height relative to the ellipsoid – a mathematical reference surface – and not directly above sea level. To obtain the actual height above sea level, it is necessary to use a geoid model, which describes the physical surface corresponding to the average sea level. In addition, there are several methods available for processing GNSS data. So what has a greater impact on the accurate height determination in the mountains – the geoid model or the method of processing GNSS measurements? The answer to this question is presented in the latest article published in GPS Solutions.

GNSS tomography-based monitoring of hailstorm events

04-02-2026

Monitoring convective phenomena, such as heavy rainfall and hailstorms, is crucial for improving our understanding of processes occurring in the troposphere and for enhancing short-term weather forecasts. Traditional observational techniques, including radiosondes, often lack sufficient temporal and spatial resolution to effectively capture the rapid and localized changes that precede severe storms. One response to these limitations is the application of integrated GNSS tomography, which combines ground-based GNSS observations with radio occultation (RO) data.
