<strong>Inter</strong> <strong>Satellite</strong> <strong>Links</strong>Simulations <strong>and</strong> Results6.2.4.3 Ground <strong>and</strong> <strong>Inter</strong>satellite Tracking (Regional Network)The pure regional tracking is an interesting option (not only) for geosynchroneous satelliteconstellations. The figures below shows the tracking accuracy for an IGSO with rare groundcontact, as well as for a GEO with no ground contact.Radial Error [cm] 1998 07 02 13:11 - 1998 07 13 01:1128.014.0Radial Std.
