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
