According to a tweet by ISRO earlier today, currently, filling of fuel for the second stage of PSLV-C48 is going on.

The nine foreign satellites, all of which are commercial in nature, are from USA (6) and one each from Japan, Israel and Italy.

According to ISRO, the RISAT-2BR1, which is a Radar imaging earth observation satellite, will be placed into an orbit of 576 km at an inclination of 37 degree. The entire process is likely to take 21 minutes, with the RISAT-2BR1 being the first of the 10 satellites which PSLV-C48 will fire into space, 16 minutes into the launch. A minute after the launch of the Indian satellite, the first of the nine foreign satellites will be sent to space.

The international satellites are being launched under a commercial agreement with NewSpace India Limited (NSIL), a central public sector enterprise of the Government of India, which was established on March 6, 2019.
