ISRO had successfully launched five British satellites on Friday, said it has planned a slew of launches, including GSLV-Mark II next month and three more navigational satellites before March 2016.

"The next launch going to take place is GSLV-Mark-II. Satellite has already reached Sriharikota and is going through final tests. We plan to make the next launch in August," ISRO Chairman Kiran Kumar said.

"We expect the next navigational satellite to be launched in November," he added,  that "right now discussions are going on for one more mission to Mars or Venus or we should look at asteroids. There is a science team which is going through this discussion."

Regarding Mangalyan he said, "Now we are back on track. Now operations have resumed. Having crossed this hurdle we expect the longevity of the satellite to be quite normal and the health of the satellite is in good health".

On the status of Chandrayaan-II, he said, "Right now it is going through the realisation phase. Work is going on".

When asked about the capacity of the commercial launch, he admitted it cannot be anything near to that. "Our maximum capacity is 1700-1800 kg, whereas international heaviest launches are somewhere around six to seven tonnes." "Today's launch is the 30th PSLV launch, so far 29 consecutive launches. This is 17th launch in Solar Synchronous Orbit and the fifth dedicated commercial launch. The first dedicated commercial launch was on May 29, 1999," Kumar said.

"So far, 27 national satellite and 45 international satellites have been launched," he said. To a query, he said, "ISRO has 28 satellites belonging to six to seven countries in next three years or so. Including today's launch, we have completed 45 commercial launches belonging to 19 countries."
