Fig. 2From: Observable-specific phase biases of Wuhan multi-GNSS experiment analysis center’s rapid satellite productsBox chart of OSBs for multi-GNSS satellites. Pseudo-Random Noise (PRNs) of satellites are sorted by satellite types and are depicted in the bottom panel. a depicts phase OSBs for GPS L1W, Galileo L1C, and BDS L2I; b represents code OSBs for GPS C1W, Galileo C1C, and BDS C2I after subtracting mean valuesBack to article page
