Complementary research directions being investigated

Computational Methods

Efficient computational methods are required for generating high-accuracy local data in a very short time making use of only local reference stations. This requires a careful identification of the algorithms, which at the same time should exploit the Galileo specific features (e.g. three frequencies) and guarantee the best compromise between the algorithms processing time and the estimation accuracy.

Data Fusion

Innovative data fusion techniques to merge local data with global/regional data are being used to predict and monitor SISE, tropo and iono corrections. We will use in the process data from IGS and EUREF networks for better estimation of local and global parameters.

Local Communication

An efficient local communication architecture is needed, being able to disseminate the SISE and the derived information with the lowest latency time using Internet or UMTS technology. This is building on the example of ESTB, SISnet and the EUREF IP project).
