Development and Educational Communication Unit (DECU) is an entity of ISRO, which connects with the common people of country at large. The activities of DECU spans following areas:

Satellite Communication Ground Systems
DECU has implemented countrywide Satellite Communication Ground systems for various societal applications in services of the common man. It promotes use of space technology in contributing to overall national development. The networks implemented by DECU, under the guidance from ISRO HQs, have been benefitting the populace in rural and remote regions of the country.

Telemedicine (TM) Network
The majority of country’s population resides in rural areas. The doctors are mostly available in urban areas. ISRO realised this and envisaged to narrow this gap using SATCOM based technology. The TM network is a VSAT network operating in Ext-C band. It connects and brings medical benefits to the underserved patients in the remote regions by connecting them to various super specialty hospitals. This TM network comprising of Hub and TM nodes spread across country is managed by DECU.
