The unit offers superior tracking integrity with any C- Band antenna up to 9.6 meters and any Ku- Band antenna up to 4.5 meters. The control unit uses the INTRAC (INtelligent TRacking Antenna Control) algorithm which has been developed and refined over a 20 year period. It offers exceptional immunity to propagation disturbances and fades, maintaining reliable pointing accuracy even at low angles of elevation in regions of high scintillation. The INTRAC 205 is compatible with INTELSAT and EUTELS
