Analysis of the effect of aliasing of the temporal signatures by high frequency effects is crucial to the proper interpretation of the data. Data from these receivers are used for our own research and also made available to the NERC EOSI archive of UK continuous GPS data.

Many natural hazards arise from or are associated with very small movements of the Earth's crust.
Measuring and interpreting this deformation is the key to understanding the geophysical processes at work and predicting future hazards. Precise terrestrial and satellite geodesy provides the tool to do this. Simultaneously, the driving force of geophysical study spurs further developments in geodetic analysis methods. We have for a number of years been conducting episodic GPS experiments to measure the long-term deformation of Greece . A further part of this research concerns the smaller but significant post-seismic deformation occurring in the few years after an earthquake, which provides information on the relationship between different layers in the Earth's crust.
