Apparently, GSAT-20 has returned to a scheduled launch on GSLV MkIII.

“The GSAT 24 will be ready for launch by this November/December or next January. The other two satellites GSAT 20 and GSAT 22 are under production,” Sivan added.

The GSAT 20 to be launched by Indian rocket Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III) will be fully propelled by electric power. The satellite will move from the geostationary transfer orbit to geosynchronous orbit with electric propulsion.

Launch has been moved to a SpaceX Falcon 9 with launch in Q2 2024.
Really astonishing since India has always been either launching communication satellites by themselves, or going with Arianespace, but at 4.7 tonnes this definitely needs a LVM-3 and I guess all of these needs to be used by their crew spacecraft program, while aboard the only choice left right now is Falcon 9.

According to ISRO's website, LVM3 is capable of launching 4,000kg into GTO. At 4,700kg, GSAT-20 could be too heavy for LVM3 which could explain why they went with a foreign launch vehicle.

Cost and launch slot availability might be considerations for NSIL as a commercial entity. Not only the launch cost, but the storage cost for GSAT-20 while waiting for a LVM-3 along with no revenue coming in for the satcom.

It appears that SpaceX might get more NSIL business if the LVM-3 could not ramp up launch cadence and alternate launchers (Ariane 6, H3 & Vulcan) are not available.

Any new news?  The satellite should ship to Florida soon to achieve a June launch (the rest of Q2 has passed).

The ISRO April monthly summary (May isn't published yet) just states:

Activities related to GSAT- 20 are progressing, along with necessary launch coordination with M/s SpaceX.

ISRO published an overview page yesterday.

Indian media predict an early July launch date:

Quote
The satellite, with a lift off mass of 4,700 kg and with a mission life of 14 years, is at present undergoing vibration tests.

The mission launch date was yet to be announced by ISRO and in all probability it is likely to take place either in the first week or second week of July.

The dates are expected to be officially announced in the coming days once all pre-launch tests are completed. [Jun 15]

If it's still doing vibration testing on June 15 then it ain't gonna launch the first half of July.

...The propulsion system of GSAT-N2 is configured with a unified bi-propellant chemical propulsion system employing MON3 as oxidizer and MMH as fuel. GSAT-N2’s power system is a single fully regulated 70V bus, consisting of solar panels for power generation, Li-Ion batteries for energy storage and peak load support, and power electronics for power conditioning and distribution. The electrical power system is designed to meet a power requirement of approximately 6 kW ...

The originally planned electric propulsion system was obviously abandoned.
This is probably why GSAT-20 became too heavy for the GSLV-III.

I wonder when the propulsion change decision was made and implemented.

Satellite is expected to leave for the US at the end of this month or early next month. Launch is expected in August:

Quote
India's high-throughput satellite #GSATN2, which is scheduled to be launched on @SpaceX #Falcon9 will leave for the US by the end of this month or early July. 1/n
Quote
Isro chairman S Somanath told me: “...Next week, we'll be clearing it. It’s all ready for shipping. And then, depending upon the readiness of the aircraft (to transport the satellite) it will go (to US) maybe by the end of this month.” 3/n
Quote
Once it reaches its destination, Somanath said, the satellite would need another 25 days or so before it can be declared ready for launch. SpaceX is yet to announce a slot for the GSAT-N2 launch, but it is expected to happen around August. 4/n

GSAT-20 has received clearance to be moved to the US.

Quote
While addressing the India Space Congress (ISC) 2024 Inaugural day, ISRO Chief S Somanath announced that its next satellite GSAT-20 will possibly be launched by August. He further said, "Our next satellite GSAT-20 is ready to be launched and will possibly be launched by August. We need to have higher payload capacity in our rockets as we plan to send people to the Moon."
