HAMSAT is ISRO's first theme based Micro-satellite meant for providing Satellite based Amateur Radio Services to the National as well as International Community of Amateur Radio Operators (HAMs).

Scheduled to be launched in May 2005 on-board the PSLV-C6 Mission as an Auxiliary Satellite, it will meet the long felt need for the Amateur Radio Operators of South Asian region who possess the required paraphernalia and operate in the UHF/VHF band based Satellite Radio Communication Channel.

The last Satellite in the LEO providing this type of service ceased operating in mid August 2003 and created a vacuum for the Mode B (UV) services. HAMSAT, once operational by June 2005, will greatly serve this purpose.

The HAMSAT Micro-satellite is India's contribution to the international community of Amateur Radio Operators. This effort is also meant to bring ISRO's Satellite Services within the reach of the common man and popularize Space Technology among the masses.

This Satellite will play a valuable role in the national and international scenario by providing a low cost readily accessible reliable means of communication during emergencies and calamities like flood, earthquakes, etc., stimulation of technical interest and awareness among the younger generation by providing them with an opportunity to develop their technological projects including offering a platform for testing New Technologies.
