Fig. 3From: Precise orbit determination for a large LEO constellation with inter-satellite links and the measurements from different ground networks: a simulation study3D mean RMS of orbit errors for each case. For each case, orbit errors of individual satellite are marked as stars and the mean of all satellites is marked as a bar. “ + ISL” means that ISL observations are included in the estimation together with observations from the station network of the same colorBack to article page
