• A new method to estimate GPS satellite and receiver differential code biases using a network of LEO satellites 

      Yuan, LiangliangORCIDiD; Hoque, Mainul; Jin, Shuanggen (GPS Solutions, 2021-03-09)
      The differential code biases (DCBs) of the global positioning system (GPS) receiver onboard low-Earth orbit (LEO) satellites are commonly estimated by a local spherical symmetry assumption together with the known GPS ...
