Simulations and ResultsInter Satellite Links6.2.8.2 Ground and Intersatellite Tracking (Full Network)The following scenario has been processed using all available types of inter satellite links, butlimiting the number of simultaneous ISL's to 6. It can be seen that orbit detereminationaccuracy is improved well below 10 cm in radial direction for both types of satellites. Thefollowing picture show the accuracy figure for the MEO satellites.Radial Error [cm] 1998 07 02 01:12 - 1998 07 07 13:12Radial Std. Dev.

Radial accuracy is nearlyas good as for the MEO, only the tangential accuracy is slightly worse.Page 134R. Wolf
