Short summary
Receiver and satellite differential code biases (DCBs) are one of the main error sources in estimating precise global ionosphere maps (GIMs) from Global Positioning System (GPS) data. This paper introduces a mathematical model for estimating satellite and receiver DCBs from a GPS network written in the MATLAB environment. Our code was tested and compared with Ionosphere Associated Analysis Centers (IAAC) and other researchers' code results. The results show an improvement for estimated DCBs.
