In December, Isro's PSLV C44 will launch Emisat.

I see that Gunter has listed the PSLV-CA as the LV version for PSLV C44.

Am I right to deduce that this is because the primary payload, EMIsat, is using the SSB-2 microsatellite bus?  And, even if there are secondary passengers, they would not overfill the PSLV-CA payload mass limits to a LEO?

(SARAL also used this satellite bus and was launched to a low polar orbit (SSO?), with secondary payloads.  SARAL massed only 346 kg.)

EDIT: cross-post/response re: similar question about the LV version for PSLV C43:
Exactly - the small mass of all payloads is a very strong hint, that the CA version will be used.

Belated cross-post re: ISRO launch cadence, apparently placing EMIsat's launch in January 2019:

Here is what Dr K Sivan told NDTV:

Q) In these next few weeks, how many missions are you doing? You have quite a packed schedule?

A) Actually that is true. If you have seen our schedule up till January,  we have 10 missions; that is, four launch vehicle missions and six satellite missions. The immediate mission is PSLV C-43. Then the GSLV will launch GSAT-7A.  Then another PSLV is going to launch EMISAT. Then GSLV Mk III will launch Chandryaan-2. Alongside, we have two procured launches that is GSAT-11 and GSAT-31. So we have totally 10 missions in a packed mission schedule.

Wasn't there a SPADEX (SPAce Docking EXperiment) payload that was supposed to be launched along with EMIsat?
Whatever happened to that?

Where does it say EMISAT in January? It says EMISAT is between GSAT 7A (19 December) and Chandryaan 2 (31 January), so it could still be launching in December, although I agree January is more likely.

Given that F11 is not going to take off earlier than December 19th, there are little chances of C44 getting launched within next 12 days.

Sorry, Steven.  I should have included the other item below...

The second piece of evidence is from:
ISRO has three launches planned over November and December.

November 14th - GSLV Mk-3 D2/GSAT-29    (Second Launch Pad)
November 26th - PSLV C43/HySiS + 30 co-passengers    (First Launch Pad)
December 14th - GSLV Mk-2 F11/GSAT-7A       (Second Launch Pad - First use of SVAB)

Source: https://timesofindia.indiatimes.com/city/kochi/isro-lines-up-3-rocket-launches-in-two-months/articleshow/66538316.cms
And:
Quote
Isro will have a busy year-end with three rocket launches.

The article doesn't preclude another launch, but the wording appears to imply an inclusive listing of launches planned through December 31.

Based on currently available information in the media, post launch speeches, interviews, EMISAT will be launched some time in end Dec or early Jan 2019. I expect it to be a PSLV-CA and launched from FLP.

Chandrayaan-2 should follow soon after from SLP on a MKIII

In a first, Isro will make dead rocket stage ‘alive’ in space for experiments - TOI
https://timesofindia.indiatimes.com/india/in-a-first-isro-will-make-dead-rocket-stage-alive-in-space-for-experiments/articleshow/67067817.cms
Quote
NEW DELHI: Can a dead rocket in space be anything but debris? Isro believes it might actually be useful. Feted for its frugality and tech savvy, the Indian Space Research Organisation is working on a new technology where it will use the last stage of the PSLV rocket for space experiments. It will perform a technology demonstration of this new system when it launches the PSLV C44 rocket in January.
Quote
Talking to TOI here, Isro chairman K Sivan said, “Normally, the last stage of a PSLV rocket after releasing the primary satellite in space becomes dead and categorised as debris. It remains in the same orbit as that of the released satellite. Now, we are working on a new technology where we will give life to this “dead” last stage of PSLV, also called PS4 stage, for six months after its launch. This rocket stage will double up as a satellite. This will be the most cost-effective way to perform experiments in space as we don’t have to launch a separate rocket for the purpose.” He said that “India is the only country in the world that is working on this new technology”.
Quote
Explaining the technology, the chairman said, “The rocket stage of PSLV C44, which will be carrying a microsat as the primary satellite in January, will be made alive with the help of new systems that will include batteries and solar panel. Even after the primary satellite separates from the PSLV, the last stage of the rocket will remain active and can be used as an experimental platform for new space technologies. Students or space scientists can use this “alive” rocket stage for space experiments for free. They can attach their small experimental module or satellite (micro or nano) in the last stage and can perform experiments in space once the PSLV delivers the primary satellite into its orbit.” He said that Isro “can do the same with the GSLV rocket as well where we can use its last stage as an experimental platform”.

I am doubtful this will launch in January. I hope isro proves me wrong.

As per ground reports, PSLV will launch right behind GSLV-F11

As GSAT-7A prepares to launch from the SLP, any sign of activity at the FLP towards assembling the PSLV inside for the EMIsat launch?

The relevant paragraph.

"The new year’s very first mission is set for January and will try out a unique experiment to re-control and rework the fourth and last stage of the PSLV-C44 rocket after it completes its job in space. C-44 is slated to carry the 150/200-kg special purpose Microsat-R to a low-Earth polar orbit."

Thanks Steve...

Do we know the list of non-Indian satellites on this mission in Jan-2019

So PS4 is being turned into an Agena equivalent.

As per sources, launch is expected on Jan-15-2019 (or in that week)
I will look out for official confirmation

Further from same article--solar power usage such as used by Progress in extended free-flight following its primary mission:
Quote
Dr. Sivan said the revived stage of the PSLV-C44 flight would be equipped with solar power systems to keep it working and monitored from ground.

And, re: RH's observation, I hope the next quote is a misunderstanding by the journalist, and not by Dr. Sivan:
Quote
ISRO Chairman K. Sivan said the trial with the expired fourth rocket stage would easily be the first of its kind by any space agency.
