I want to understand how satellites are accommodated in PSLV. I know about few configurations and adaptors that've been used in the past. Is there any document which gives detailed info on Multiple Satellite Adaptor Version 2 (MSA-V2), Multiple Satellite Adaptor Version 8 (MSA-V8) and other adaptors that are there? I've noticed that there are support structures on Equipment Bay. I need info on them. What variations are there when it comes to Dual Launch Adaptors. I want to learn about those as well.


On page no 553, four Payload Envelope Configurations are shown. I want to learn more about those. Specifically about the two middle configurations.

If there's anyone who knows about this or knows someone who knows about this, please answer.

    $\begingroup$ Apart from MSA-V2 and V8, apparently there is MSA-V5 as well. Here is a tender for it, web.archive.org/web/20180917170635/https://… Vertical dispenser has not been used till date, as far as I am aware. Unfortunately detailed documents on these are not public and all we have are visual references from campaign images, like this flat deck config from PSLVC-34 etc. twitter.com/COMDEV_Intl/status/742349375045787648/photo/1 $\endgroup$

  • $\begingroup$ Thanks a lot for the info. Do you think the ISRO would reveal non-confidential info on this if I reach out to them? $\endgroup$

    $\begingroup$ They should, do try to contact them. Ideally this all should be public in a form of user manual or as brochure. $\endgroup$
