ESAs Navigation Support Office at ESOC generates a wide range of geodetic (earth orientation parameter, station coordinates), atmospheric (troposphere and ionosphere estimates/models), time (station clock offsets, drifts and characteristics) and satellite (orbits, clock offsets, drifts and metadata, e.g. estimated code biases and phase centre offsets, variations), reference and monitoring products.

The products are generated by using different space geodetic techniques such as GNSS, DORIS and SLR and finally by combinations of these techniques. A public subset of the products can be found on our web server ( ) and can be retrieved via a file browser or http download methods (e.g. wget or curl).
