“We are working for a January launch. It will be toward the end of January. The date has to be fixed,” Indian Space Research Organisation Chairman A S Kiran Kumar told reporters here.
Of the 83 satellites, 80 belong to Israel, Kazakhstan, Netherlands, Switzerland and the US. They weigh about 500 kg.
The three Indian satellites are Cartosat-2 series, weighing 730 kg as primary payload, and INS-IA and INS-1B, weighing 30 kg.
Setting a record in its space programme, ISRO in June had successfully launched 20 satellites, including its earth observation Cartosat-2 series, in a single mission on board PSLV-C34 from the spaceport in Sriharikota in Andhra Pradesh.
The space agency had earlier sent 10 satellites into orbit in a single mission in 2008.
Calling 2016 a “good” year, Kumar said ISRO would launch at least five communication satellites in 2017.
“It (launches) will be more next year, we are actually looking at almost something like five communication satellites, then many more others. Some earth observation also,” he said in response to a question on the number of launches that can be expected in 2017.
