XPoSat is a space observatory satellite being developed by ISRO and the Raman Research Institute. It'll be launched by SSLV, probably in Q4 2022.
Payloads on XPoSat:
1) POLIX (Polarimeter Instrument in X-rays) developed by the Raman Research Institute.
2) XSPECT (X-ray Spectroscopy and Timing) developed by URSC, ISRO.

POLIX is an X-ray Polarimeter Instrument for Astronomical Observations under development at the Raman Research Institute. It is the only instrument in the energy band of medium energy X-rays, 8-30 keV, and is the main payload on the soon to be launched dedicated ISRO satellite XPoSat. A completely in-house design, and development, of the Qualification Model (QM) of POLIX was completed in the current year and has successfully undergone space qualification tests like vibration test and environmental test at the UR Rao Satellite Centre (URSC).

From "Space Research in India" 2020-2021 report
here:
XSPECT: X-ray spectroscopy and Timing on XPoSAT
XPoSat is India’s X-ray polarimeter mission carrying POLIX (A Thomson scattering polarimeter) and XSPECT (X-ray Spectroscopy and Timing) payloads. XSPECT is large area spectrometer payload and has a unique opportunity to observe astrophysical sources for very long durations to study their spectral and temporal variability in 0.8 to 15 keV x-ray band.
XSPECT is configured as two detector packages connected to a single electronics packages, which powers the detectors and does the necessary signal conditioning and has interface with spacecraft. Two different Field of Views (FOV) collimators, 2°X2° and 3°X3 are used enabling us to efficiently model-out the X-ray sky background. Swept Charge Device (SCD)s are used as detectors (effective area of ~35cm2 @ 6keV). These detectors enable XSPECT to have pile-up free observations at the expected count-rates with a very good energy resolution of less than ~ 200 eV @ 5.9keV. XSPECT provides a timing resolution of ~2 msec.
Polarimeter Instrument in X-rays (POlIX): The POLIX payload on-board XPOSAT aims at measuring the degree and direction of polarisation of X-ray photons from about 50 potential cosmic sources of interest in the energy band 8-30 keV. The instrument is being developed by Raman Research Institute, Bengaluru with the support of URSC.

From "Space Research in India" 2020-2021 report
here:
X-ray Polarimeter (POlIX)
During the past few years, RRI has been designing and building an X- ray polarimeter (POLIX) instrument for astronomical observations. POLIX is the main payload onboard the small satellite mission of ISRO called XPoSat dedicated for X-ray polarization measurement from cosmic sources. X-ray polarimetry is an unexplored area in high energy astrophysics. X-ray polarization measurements can give valuable insights into (i) the strength and the distribution of magnetic field in the sources (ii) geometric anisotropies in the sources (iii) their alignment with respect to the line of sight and (iv) the nature of the accelerator responsible for energizing the electrons taking part in radiation and scattering. Development of the Qualification Model (QM) of the X-ray Polarimeter instrument POLIX has been completed and assembly and tests of the Flight Model (FM) is ongoing.

No mention of upcoming SSLV launches in recent months. Apparently, we know ISRO's full orbital launch schedule through July 2023. Thus launch must be NET July or August Q3.
For now, I have re-edited the the thread title from "NET Q3 2023" to date "TBD."

I edited the thread title.
Given the mass and orbit, I think a PSLV-CA will be sufficient, assuming this is the sole payload.
This could also be the "missing" C59 launch.

Confirmed for PSLV:
An excerpt from Malayalam language interview with ISRO chairman on Asianet News dated 26 Aug 2023:
INSAT-3DS on the GSLV, XPoSAT on the PSLV, SSLV-D3 launch, commercial launch of PSLV, unmanned Gaganyaan launch on LVM3,are upcoming missions over the next few months. Will give you enough news items in the next few months.

https://twitter.com/chethan_dash/status/1740668328522534949#Update #Space #India
India’s space activity in 2024 is expected to start with a launch on the first day, with @isro having begun last leg of pre-launch preparations to put into space #XPoSat on a #PSLV, whose last stage will host 10 other payloads after injecting main sat. 1/n
Multiple Isro officials confirmed to TOI that the launch is scheduled for January 1 as on date. With XPoSat, India is on the verge of a groundbreaking leap in space-based X-Ray astronomy. 2/n
Unlike previous missions that focused predominantly on imaging, time-domain studies, and spectroscopy, XPoSat aims to explore the polarisation of intense X-Ray sources, introducing a novel dimension to X-Ray astronomy, the space agency said. 3/n
“The mission's objectives include measuring X-Ray polarisation and conducting long-term spectral and temporal studies of cosmic X-Ray sources,” Isro said, adding that the anticipated mission life is around 5 years. 4/n
Scheduled for observation from Low Earth Orbit (LEO) at an altitude of approximately 650km and a low inclination of around 6°, XPoSat carries two payloads. These payloads enable simultaneous studies of temporal, spectral & polarisation features of bright X-Ray sources. 5/n
“The primary payload, POLIX (Polarimeter Instrument in X-rays), developed by
@RRI_Bangalore
focuses on measuring polarimetry parameters in the medium X-ray energy range. It comprises a collimator, scatterer, and four X-ray proportional counter detectors,” Isro said. 6/n
“XSPECT (X-ray Spectroscopy and Timing), developed by UR Rao Satellite Centre, offers fast timing & excellent spectroscopic resolution in soft X-rays. It's capable of observing various sources, including X-ray pulsars, black hole binaries &active galactic nuclei,” Isro added. 7/n
Isro said XPoSat’s significance lies in its ability to act as a diagnostic tool for examining the radiation mechanism and geometry of celestial sources. 8/n
“By analysing X-Ray polarisation signatures, scientists can measure the mass and spin of accreting black holes, explore accretion flow, outflow, and jets, estimate strong magnetic fields & unveil the radiation zone and particle acceleration processes in pulsars,” Isro said. 9/n
10 Other Payloads On POEM: Aside from #XPoSAT, the main satellite, the PSLV will carry 10 more instruments to Space on its last stage — the PSLV Orbital Experimental Module or POEM. 10/n
They are; Radiation Shielding Experimental Module (RSEM)” to evaluate Tantalum coating effectiveness, by TakeMe2Space, Hyderabad; Women Engineered Satellite (WESAT) to compare Solar Irradiance and UV Index, by LBS Institute of Technology for Women… 11/n
…BeliefSat-0, an amateur radio satellite by KJ Somaiya Institute of Technology; Green Impulse TrAnsmitter (GITA), a green bipropellant CubeSat propulsion unit by Inspecity Space Labs Private Limited… 12/n
…Launching Expeditions for Aspiring Technologies - Technology Demonstrator (LEAP-TD) for demonstration of subsystems of microsatellite by space startup Dhruva Space.” 13/n
The other five include, two instruments from Bengaluru based firm Bellatrix Aerospace — “RUDRA 0.3 HPGP” the green monopropellant thruster and “ARKA-200”, a heater less hollow cathode for Hall thrusters — two payloads by VSSC and one PRL. 14/n
The two VSSC instruments are “Fuel Cell Power System (FCPS)” for demonstration of fuel cell and Silicon-based high energy cell, while the PRL payload, the Dust Experiment (DEX) will measure interplanetary dust count. n/n

The third stage (PS3) I estimate to be in a -530 x 650 km x 17 deg orbit, with impact around 0427 UTC in the Pacific near 120W 15S.
The PS4 stage makes quite a big inclination change to 6 deg, and then for burns 2 and 3 back up to 9.6 deg.
