ConclusionsConclusionsA set of instruments were installed in the

frame of the LISN project

Part of LPIM routines were used to compute VTEC with a delay of 5 minutes

A prototype platform for future services

Future WorksFuture Works

Modify LPIM to accept NTRIP data format as input

Include more stations so a regional interpolation can be done
