This news report makes it sound like Anvesha (aka Anwesha) is going with XPoSat on an SSLV. Not sure if it's the same SSLV mission or two separate SSLV missions. Confusing.

Following that [Aditya L1] will be the orbiting of Anwesha satellite and XPoSAT- a X-Ray Polarimeter Satellite with the ISRO's Small Satellite Launch Vehicle (SSLV). It will be the country's dedicated polarimetry mission to study the dynamics of bright astronomical X-ray sources in extreme conditions, the government said.

Quote
The launch of the Radar Imaging Satellite- RISAT-1B aboard the PSLV rocket is planned in the second half of 2023.

Quote
The Indian space agency with its Geosynchronous Satellite Launch Vehicle (GSLV) plans to orbit INSAT-3DS and two IDRSS (Indian Data Relay Satellite System) satellites.

Quote
These rocketing missions apart, ISRO will be testing the various systems that will go into its LVM3 rocket for the maiden human space mission.

Anvesha and rideshares delayed into 2025, apparently.

There are three remaining PSLV launches this (chronological) year.

Previous remarks, same page, mention Proba-3 launch as an immediate future launch scheduled for December 2024.  Perhaps the Anvesha launch was scheduled for sometime in January through March when this section of the report went to print, but is since delayed?

This section is to talk about return to flight of PSLV after a failure on PSLV-C61.

As you all know ISRO called that satellite user funded satellite. My guess is they are launching a SSLV EOS satellites (Microsat) with possibly rideshare or POEM.

“Nine major launches have been scheduled to be launched before the end of this financial year (March 2026). The next major mission is the LVM3-M5 mission.
