Fig. 4From: Multi-GNSS clock combination with consideration of inconsistent nonlinear variation and satellite-specific biasClock differences between ESM, GFM, GRM, JAM, WUM and COM for GPS and GLONASS on DOY 001, 2018. Different colors indicate different satellites and the values in black are the mean STDevs for each constellation. The average bias of all satellites is subtracted from GLONASS clock difference for clarityBack to article page
