The LAM will be fired again on Wednesday to make final alterations to the satellite's orbit.

The 12 extended C-band transponders onboard will boost the country's efforts in tele-education, tele-medicine, disaster management support, telephone services etc.

With the GSAT-12 mission brought to a successful close ISRO is gearing up for the launch of two additional satellites. The first one will be the Indo-French joint venture, the Megha-Tropiques satellite, which is likely to go up by the end of September on board the PSLV-C18.

The 1,000-kg Megha-Tropiques is being put together by the ISRO Satellite Centre, at Bangalore. It will lofted into an orbit at an altitude of 867 km and will be used to study weather conditions in the tropical regions.

The second satellite will be critical for the country's security and will be a surveillance satellite. The RISAT-1 (Radar Imaging Satellite) is expected to be put into orbit December-end onboard the PSLV-C19.

RISAT will be able to survey and image the earth day and night in all weather conditions.
