Re-reading it I got to the page on "Combination of GNSS Measurements" - and the geometry free combination of L1 and L2 is exactly what I was looking for; some quantity proportional to TEC that I can correlate with the daily excursions of the Ublox PPS. So, yeah, thanks! That gave me just what I needed! :) Now to cobble up a RINEX parser.. > You might also look into seeing if you can put your data in a form to be > processed by GIPSY at JPL - they have a service where you can upload your > raw observables and they post process it. > GIPSY solves using PPP, does it not? I already process the data with PPP from each of the receivers using both the NRCan online service and locally using gLAB - using one to "sanity check" the results from the other, but I'll have another look at GIPSY.
