Practical analysis of using PPPH and raPPPid for Precise Point Positioning in Europe

Reports on Geodesy and Geoinformatics
Assessing the reliability of using open-source software packages for post-processing of the Global Navigation Satellite System (GNSS) is essential since GNSS modernization has the potential to assist satellite navigation users.

The benefits and tolerance of exercise in myasthenia gravis (MGEX): study protocol for a randomised controlled trial

Trials, 2018
Background Research exploring the effects of physical exercise in auto-immune myasthenia gravis (MG) is scarce. The few existing studies present methodological shortcomings limiting the conclusions and generalisability of results. It is hypothesised that

Impact of flex power on inter- and intra- differential code bias variation

Geodesy and Geodynamics
Differential Code Bias (DCB) is the time delays between two different GNSS signals, which is crucial for GNSS positioning. Previous studies have shown that it can be significantly affected by the flex power operations in satellites. This study proposes a
