SATELLITE OVERVIEW
ABS-3 has introduced high-powered capacity to Sub-Saharan Africa and is helping to fulfil the insatiable demand for communications in the region.
A Space Systems/Loral FS1300 satellite, ABS-3 features a Ku-band and C-band payload as well as a Ka-band beam that is restricted for government use.
