🛰️Are there any serious pitfalls in the multi-epoch filtered PPP-RTK corrections that the #GNSS users should avoid ? Apparently yes. New paper in Journal of #Geodesy, where we demonstrate such intricacies and also their user-impact:

Just published a paper on generating ionospheric corrections for PPP-RTK, addressing challenges associated with wide-area networks such as large inter-station distances and appropriate weighting of corrections at the user end. Thanks @RemoteSens_MDPI
