Relative gravity data
There is a ongoing project of measurement of ~200 relative gravity points anchored to the absolute ones.
A first reconnaissance was performed in September 2014 to determine the location of the future campaign measurements (mission J. Hinderer, J.D. Bernard)

Absolute gravity data
A campaign of absolute gravity measurements was carried out from November 25, 2013 to December 5, 2013.
Five absolute points were observed at Patras, Nafpaktos, Panormo, Temeni and Chelmos (see map).
Near each absolute point an auxiliary point was established and connected to the absolute one for easy re-occupation in the future.
The points Temeni and Chelmos were established so as to constitute a calibration base (~1600m of difference of elevation) measurable in less than four hours (good road and time needed for the loop and measurements with relative gravimetre at the points).

There are various methods to process the kinematic GNSS data
- local processing / on-line processing
- dual differences / PPP
Most of our dual difference processing calculations are made with the old but good PNAV software. As PNAV requires data at the Ashtech format BES, this requires a difficult part of preprocessing of the data!
For the PPP processing we use locally GIPSY version 6.4 and GIPSY-X
There are also various good on-line PPP processors, see this page
