Workshop 2017 - Min Li - This contribution aims to bring to light the variations of receiver DCB over relatively short time intervals (ranging from one entire day down to an hour). The DLR-based method is extended to estimate the receiver DCBs with hourly time resolution using IGS-provided Global Ionosphere Maps (GIMs). Based on 1 month of data collected within the Multi-GNSS Experiment (MGEX) of the International GNSS Service (IGS), hourly receiver DCBs for the publicly available signals of GPS, GLONASS, Galileo and BDS have been determined. The intra-day stability of receiver DCB was thereby analyzed over a month period.
