Optimal spatial assessment of short-time step precipitation for hydrological modelling is still an important research question considering the poor observation networks for high time resolution data. The main objective of ...

The suitability of an improved GPS time and frequency transfer technique, Integer Precise Point Positioning (IPPP), for the frequency comparison of optical clocks on the 1e−16 level was investigated. An optical fiber link ...

For highly precise and accurate positioning and navigation solutions with GNSS, it is mandatory to take all error sources – including phase center corrections (PCC) – adequately into account. These corrections are provided ...

The Swarm mission launched on November 22, 2013 consists of three identical satellites in near-polar orbits, Swarm A and C flying almost side-by-side at an initial altitude of 460 km, Swarm B flying in a higher orbit of ...

Global satellite navigation systems (GNSS) are a standard measurement device for deformation monitoring. In many applications, double-differences are used to reduce distance dependent systematic effects, as well as to ...
