Earth Station Background

The satellite uplink facility of 9 channels of DDK Delhi, also called as Earth Station was commissioned in 2007. The technology available those days was not spectrum efficient and the compression technique used earlier was MPEG-2 in DVB-S format which resulted in spectrum utilisation of approx. 4 MHz per channel. In order to replace the old outdated and obsolete equipment and also save precious spectrum, the compression chain of the Earth Station is now replaced with state of art new equipment which uses MPEG-4 compression and DVBS-2 standards resulting into reducing bandwidth requirement per channel to half i.e. 2 MHz per channel.This spectrum efficient technology will result in increasing capacity of the Earth Station to almost double the number of channels in the same bandwidth.
