Satellite Orbit and Ephemeris Determination using Inter Satellite Links

Simulations and ResultsInter Satellite Links6.2.3.2 Ground and Intersatellite TrackingIn this scenario, intersatellite links provide also an enhancement in accuracy similar to theIGSO Walker constellation.Radial Error [cm] 1998 07 02 08:59 - 1998 07 11 02:5930.0Radial Std.
