The bigger launches include...IRNSS-1J, as part of India's navigation constellation, which will carry an indigenous atomic clock.

Do "we" know if IRNSS-1J is intended for GEO or inclined GEO?

Do "we" know if IRNSS-1J is intended for GEO or inclined GEO?

From the government annual (2020/2021) report (pdf attached here), page 51: NVS-01, also known as IRNSS-1J, will take IRNSS-1G's slot in geostationary orbit.
Five replacement satellites are planned: NVS-01 through 05.

Also note that the launch vehicle has been "upgraded" from PSLV-XL to GSLV MkII.  From page 60:
Quote
Future Missions of GSLV planned to be launched in 2021 are GSLV-F10/EOS-03, GSLV-F12/EOS-05, GSLV-F14/NVS-01. These missions are in various stages of realisation.

Given the third stage failure of GSLV Mk II, I expect that this launch will be delayed through the investigation and mitigation.

Whether or not this launch will be the Return To Flight for GSLV MkII, I don't know.

I'm changing the thread title to TBD 2022.

GSLV Mark 2 will be back

The GSLV Mark 2 will soon be back on the launch pad. The IRNSS satellite will be launched on GSLV as part of a naval project. The problem has been identified six months ago and necessary changes have been made. Nisar is also preparing for the NASA-ISRO joint mission. The Aditya L1 mission to study the Sun will also be completed later this year. GSLV Mark 2 should be used for this mission as well.

The Minister informed that the Failure Analysis committee has recommended improvements to enhance the robustness of the Cryogenic Upper Stage for future GSLV missions. The GSLV vehicle with the required modifications in the Cryogenic Upper Stage is expected to be ready by the third quarter of 2022. The satellite identified for the next GSLV mission is expected to be ready for launch in the fourth quarter of 2022. Therefore, no delay is envisaged with respect to the related projects due to the failure.

He said ISRO has planned to launch four NavIC satellites and the first one will go up in 2023."

"Any new news? 👀"

  They seem to have gone quiet on the GSLV Mk2 vehicle. Have the troubles with the CUS-15 stage been dealt with successfully?

   That would be wonderful if a GSLV Mk2 with the first in a  new series of IRNSS went up in March!

From the post launch speeches after the successful launch of SSLV D2:
Preparing GSLV Mk.III for 36 OneWeb satellites in middle of March. Commencing launch campaign immediately after today's launch for PSLV C55 for end of March on commercial mission. Using new facility. Preparing for landing demonstration of RLV in a few days time.

For Gaganyan have abort and recovery mission today, another abort and recovery mission and trying for uncrewed mission before end of year.

GSLV for NAVIC series satellite prior to NISAR, scheduled for end of this year. More PSLV missions as well.

Intelsat License LLC (“Intelsat”) herein requests 30 days of Special Temporary Authority (“STA”),1 commencing March 18, 2023, to use its Nuevo, California C-band earth station, Call Sign E040125, to provide launch and early orbit phase (“LEOP”) services to the NVS-01 satellite.2 NVS-01 is expected to launch on March 18, 2023. Intelsat expects the LEOP period to last approximately seven days.

Why wasn't this launch specifically mentioned as happening soon at this opportunity a few days ago?

 That would be amazing if there is a launch by GSLV Mk2 by the end of March.  Fuzzy or conflicting information on this launch.
