Presser:Spaceflight Announces Next Three Rideshare Missions on ISRO’s PSLV, Slated Through the End of 2019The rideshare service provider will launch 14 customer satellites from four different organizations on the next three launchesSEATTLE – Oct. 15, 2019 – Spaceflight, the leading satellite rideshare and mission management provider, today announced it will launch 14 more spacecraft from India’s Polar Satellite Launch Vehicle (PSLV) this year. Payloads will launch on PSLV’s C47, C48 and C49 missions, scheduled to launch in November and December 2019 from India’s Satish Dhawan Space Center. Customers aboard the missions include Analytical Space, Spire, iQPS and Kleos Space.<snip>PSLV C48, slated for early December, will carry Japan’s iQPS SAR microsatellite and four multi-payload Earth observation nanosatellites that add to Spire Global's constellation of maritime, aviation and weather monitoring satellites.
ISRO Chairman giving final congratulations. Coming back "very soon."
I think the PSLV-XL( with 6*12 tonne strap ons) would be needed.
Or are they referring to Arianespace's launching of Indian satellites, when referring to the extra mission?

No dog leg manoeuvre?
Are the RISAT-2BRs designed to "stack" under the payload fairing? One would have to be constructed to bear the weight of the other through the rigors of launch.Or, does ISRO have a SYLDA-like device for dual co-payloads?If the answer to both of my questions is no, then I deduce that both RISAT-2BRs cannot be launched on the same PSLV, in the immediate future (now to the end of the year).
Drawing of RISAT 2B from the press kit. Looks like a large deployable antenna on top of the vehicle. Mass is 615 kg to 557 km 37° orbit. Radar frequency is X-Band. Applications include agriculture, forestry and disaster management support.
Interesting re: adding four PSOMsDoes adding first stage performance leave more delta-v for the PS4 after the deployment of RISAT-2BR1?For instance, will the operational orbit for QPS-SAR 1 differ from that of RISAT-2BR1? Delta-v could be for orbit raising or lowering to deploy a secondary payload before the 4th stage end of mission.
PSLV-C48 will also carry 9 customer satellites of Israel(1), Italy(1), Japan(1) and USA(6) as co-passengers. These international customer satellites are being launched under a commercial arrangement with NewSpace India Limited (NSIL).
What are the remaining two USA satellites, and the one each from Israel and Italy?

What bothers me is the fact that the total payload mass is within the CA's capability (between 600 and 700 kg), yet a slightly-more powerful PSLV is being used for this mission.
It is strange they went for a QL variant when payload mass is within CA's payload capacity. Maybe excess S12 solid motors lying around?

URSC Director. Solar panels of RISAT 2BR1 have been deployed. Cartosat 3 is working well. Saying "third satellite in series in two months". Not sure if he means RISAT 2BR2.
Nice launch and mission! Why the huge discrepancy between the original schedule for RISAT-2BRR2 and the new reputed date of February? Maybe the preparation for SSLV-1?
Hmm...I thought the main satellite is supposed to be a secret....
Nice video of the launch, as viewed from Chennai

Has anyone answered, or found the answer to, why a PSLV-QL was used on this launch, as opposed to Core Alone (or DL for that matter)?
Quote from: zubenelgenubi on 02/03/2020 09:49 pmHas anyone answered, or found the answer to, why a PSLV-QL was used on this launch, as opposed to Core Alone (or DL for that matter)?I don’t know the answer, and I was asking the same question.My logic is that the lighter the payload, the less capable variant of a rocket family you use to launch it.
Circling back to this 2019 mission:There was discussion that the rocket had larger capacity than was used.This image looks to me like a dual launch adapter rather than the usual payload adapter for single-main-payload missions. There is a cataloged debris object 2019-089G which SpaceTrack tags with radar cross section = LARGE.It has been pointed out to me that the inclination versus time of object G shows a change in May 2020 suggesting maybe that something finished outgassing?Maybe there was a dummy second payload that replaced a planned second primary payload?Interested in other interpretations.
