The Indian Space Research Organisation (ISRO) plans to launch four satellites later this year.

Vikram Sarabhai Space Centre (VSSC) director PS Veeraraghavan told the Press Trust of India that the ISRO would be launching the satellites this December.

“Currently the two rockets are being assembled,” he said.

VSSC is one of the ISRO centres.

The two rockets that will carry the satellites include the polar satellite launch vehicle (PSLV) and the heavier geosynchronous satellite launch vehicle (GSLV).

The PSLV will carry three payloads including Resourcesat and two small satellites, each weighing around 90kg, made in Singapore and Russia.

The GSLV will launch the INSAT series communication satellite.

ISRO aims to double the number of rocket launches to eight a year, according to Veeraraghavan.
