INSAT-2D

Launch Date: 04.06.1997

INSAT-2D

INSAT-2D, the fourth satellite in the INSAT-2 series was an exclusive communication satellite launched successfully by Ariane-4 from Kourou, French Guiana on June 4, 1997. The bus system configuration of INSAT-2D was similar to that of INSAT-2C with minor modifications. It carried 12 C band, 6 extended C band, 3 Ku band, 1 MSS forward and return transponder and 1 BSS S band transponder. INSAT-2B, INSAT-2C & INSAT-2D were co-located in the geostationary orbit thus enabling efficient use of allocated orbital slots. However the satellite became in-operational in October 1997 due to power bus anomaly.  It was later replaced by INSAT-2DT.
