Could be this one - another Earth observation satellite for the Singaporean government.

PSLV-C55/TeLEOS-2 and PSLV-C57/DS-SAR (NSIL sponsored commercial launches)

DS-SAR satellite acquired by Singapore’s defence technology agency & ST Electronics, Feb 1, 2018 by Deyana Goh

DS-SAR

If it is similar in size and mass to the other SAR satellites produced by IAI, as Gunter has it listed, then it will likely be launched by a PSLV-CA, as the first TECSAR was.

TECSAR

We will see if there are any other payloads.

These low-inclination orbit pointing NOTAMs were released some days ago and it was uncertain whether they are meant for the launch of Aditya-L1 instead (which fits with previously reported rocket serial numbers, however it was reported for an August-September launch before hand).

However this co-passenger report indicates the notices above are for this launch:

Our first 12U-class satellite has been despatched for launch next month via an ISRO PSLV, our 4th satellite launch of the year! This will be hosting a compelling AOCS; coupling an Aliena Pte Ltd Hall thruster with Aurora Propulsion Technologies resistojets! @spacenews @ESABICUK

All major Earth observation satellites from Singapore before (TeLEOS-1/2, DS-EO) are in low inclination LEOs that would maximize coverage frequency for the nation.

How do we know this is C56? The previously published information gave the vehicle as C57. ISRO has launched vehicles out of sequence before, e.g., C30 on 28 September 2015 was before C29 on 16 December 2015.

Launch date is now July 26.

The Polar Satellite Launch Vehicle — C56 (PSLV-C56) mission is expected to lift off from the Satish Dhawan Space Centre towards July-end — July 26 as per the latest updates.

ISRO will be using a ‘core alone’ variant of the PSLV for this mission, S. Unnikrishnan Nair, Director of the Vikram Sarabhai Space Centre (VSSC), ISRO’s lead facility for launch vehicles, told The Hindu.

Quote
A commercial mission, the PSLV-C56 will have seven payloads in all including the 351.9 kg earth observation satellite DS-SAR (short for Synthetic Aperture Radar) from Singapore. The others are Arcade (23.58 kg), Velox-AM (23 kg) and Orb-12 Strider (12.8 kg). The remaining three are nanosatellites weighing less than 10 kg each. They are the Galassia-2 (3.84 kg), SCOOB-II (4.1 kg) and NuLIon (3.05 kg), according to a list provided by the VSSC. These satellites will be placed in a Low Earth Orbit (LEO).

PSLV-C56/DS-SAR Mission

The launch of PSLV-C56 carrying DS-SAR satellite, along with 6 co-passengers from the first launch-pad of SDSC-SHAR, Sriharikota is tentatively scheduled towards the end of July 2023.

PSLV-C56 is configured in its core-alone mode, similar to that of C55. It would launched DS-SAR, a 360 kg satellite into a Near-equatorial Orbit (NEO) at 5 degrees inclination and 535 km altitude.


DS-SAR
The DS-SAR satellite is developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering. Once deployed and operational, it will be used to support the satellite imagery requirements of various agencies within the Government of Singapore. ST Engineering will use it for multi-modal and higher responsiveness imagery and geospatial services for their commercial customers.

DS-SAR carries a Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries (IAI). This allows the DS-SAR to provide for all-weather day and night coverage, and capable of imaging at 1m-resolution at full polarimetry.

The co-passengers are:
1) VELOX-AM, a 23 kg technology demonstration microsatellite.
2) ARCADE Atmospheric Coupling and Dynamics Explorer (ARCADE), an experimental satellite
3) SCOOB-II , a 3U nanosatellite flying a technology demonstrator payload
4) NuLIoN by NuSpace, an advanced 3U nanosatellite enabling seamless IoT connectivity in both urban & remote locations.
5) Galassia-2, a 3U nanosatellite that will be orbiting at low earth orbit.
6) ORB-12 STRIDER , satellite is developed under an International collaboration
