The satellite will be launched on the Indian Space Research Organisation's Polar rocket in August.
“We are looking at including 25 to 30 small satellites of foreign customers in the next PSLV launch depending on the configuration. They may total 250 kg,” said Rakesh Sasibhushan, Chairman and Managing Director of Antrix Corporation Ltd, which exports ISRO’s products and services.
C-42 would have new customers as well as repeat users of the Indian launch vehicle, he told The Hindu. The main load in it from ISRO could weigh around 800-1,000 kg.Mr. Sasibhushan said the international launch market was “looking very good” and Antrix had sought two fully commercial launches (i.e., without an ISRO satellite) each year from the space agency.
From this article the nominees for this launch areCartosat 3Oceansat 3RISAT 1Ahttps://www.hindustantimes.com/science/chandrayaan-2-oceansat-3-isro-s-launch-plans-in-2018/story-KEZikZnvCSSvgARD9Y59QN.html
According to isros own manifest however both cartosat-3 and oceansat-3 wont be ready till october/november so unless those satelites are ready ahead of time i dont think it will be them either.

Do you have a link for the ISRO manifest? I couldn't find it on the ISRO website. This page only lists GSAT 11, Chandrayaan-2 and GSAT 29.https://www.isro.gov.in/missions
Thanks K210! Perhaps the ISRO payload is EMISAT, which was scheduled to be available in the first quarter of 2018.http://space.skyrocket.de/doc_sdat/emisat.htm

What version of PSLV will this launch use?
Quote from: zubenelgenubi on 08/15/2018 03:47 pmWhat version of PSLV will this launch use?Probably PSLV-XL.
A new set of future satellites called hyperspectral imaging satellites is set to add teeth to the way India is gleaned from about 600 km in space. The Indian Space Research Organisation (ISRO) says it plans to launch a full-fledged niche Earth observation (EO) satellite - called the Hyperspectral Imaging Satellite or HySIS - using a critical chip it has developed.
About a decade ago, ISRO added another EO niche with microwave or radar imaging satellites RISAT-1 and 2 that could 'see' through clouds and the dark - an important feature useful for the military and security agencies.
'Hyspex' imaging is said to enable distinct identification of objects, materials or processes on Earth by reading the spectrum for each pixel of a scene from space. The payloads development centre, Space Applications Centre, Ahmedabad, designed the architecture of the chip which was made at ISRO's electronics arm, the Semi-Conductor Laboratory, Chandigarh. The result was a detector array that could read 1000 x 66 pixels.
ISRO first tried it out in an 83-kg IMS-1 experimental satellite in May 2008. The same year, a hyperspectral camera was put on Chandrayaan-1 and used to map lunar mineral resources. Very few space agencies have such a satellite; a German environmental satellite called EnMAP is due to be launched on an Indian booster in 2018.
In October itself, another launch of PSLV C43 is scheduled that will carry HySIS or hyperspectral imaging satellite. The satellite is set to add teeth to the way India is gleaned from 630 km altitude as it will enable the country to see in 55 spectral or colour bands.

And, even 30 more secondary passengers would not overfill the PSLV-CA payload mass limits to a SSO?(SARAL also used this satellite bus and was launched to a similar polar orbit, with secondary payloads. SARAL massed only 346 kg.)
Launch date has slipped to mid november according to the reaktor hello world cubesat website (one of the payloads on C43). Source: https://reaktorspace.com/reaktor-hello-world/
Also this might end up being a XL variant rather than a CA variant reason being that a extra 450 kg payload was intended to fly on C42 (Which was supposed to be XL variant rather than CA). If that extra 450 kg payload is included on this mission than this will become a XL variant due to payload mass being too heavy for CA and G variant of PSLV being retired.

Talking to TOI, Isro chairman K Sivan said, "We are going to launch HySIS at 9.59 am on November 29 from Sriharikota. Over 30 foreign satellites, including nano and mini satellites, will also be launched along with the main payload. Out of the 30 commercial satellites, 23 are from the US."
The satellite, which can see in 55 spectral or colour bands from 630 km above the ground, will be used for a range of applications like agriculture, forestry and assessment of coastal zones, inland waters, soil and other geological environments. Being an earth observation satellite, HySIS will also be used by the military for surveillance purpose. The optical imaging detector array chip in the HySIS satellite has been designed by Isro's Ahmedabad-based Space Applications Centre and manufactured by its electronic arm, Semi-Conductor Laboratory, Chandigarh.The hyspex technology is still an evolving science and has become a new global trend. Hyperspectral imaging combines the power of digital imaging and spectroscopy. It collects and processes information from across the electromagnetic spectrum. Hyspex imaging enables distinct identification of objects, material or processes on the Earth by reading the spectrum for each pixel of a scene from space.
HySIS carries two payloads in visible and near infrared regions of the electromagnetic spectrum. This earth observing imaging spectrometer will operate in the 0.4 to 0.95µm spectral range, will have 55 spectral bands with 10 nanometre spectral sampling and 30 metre spatial sampling. Push-broom scanning mode is the operating mode of this sensor from a 630-km orbit. According to Isro officials, 1000 X 66 pixels were designed to be readout, from both top and bottom directions, using four analog video ports to meet the frame rate requirement.
Metal strapping was used for swiftly transferring integrated charges from image to storage region, in order to reduce image smear. Designs (both at chip and package levels) went through detailed review, before clearing for mask making and package fabrication, by a team consisting of members from Isro's SCL (Semiconductor Laboratory) and SAC (Satellite Application Centre).HySIS spacecrafts carries the Hyper Spectral Compact Imaging in VNIR (Visible and Near Infrared) and SWIR (Shortwave Infrared) spatial region in 60 and 256 contiguous spectral bands respectively, with 10 nm bandwidth providing 30m spatial resolution and covering a swath of 30 km at 630 km orbit.
According to the previous and latest mission kits it appears that C43 is the first flight of the Higher Performance HPS3 stage which replaces the standard PS3 stage as part of the overall PSLV Higher Performance Project (PSLV-HP).

He said the PSLV fourth stage has a 'cluster' of two liquid engines. I don't think that's correct. The stage has a twin liquid engine configuration, whereas the first stage of the GSLV Mark 3 has a cluster of two Vikas type liquid engines. I do know there's a difference . K210, mind giving a very brief definition of clustering? Just a one time thing
As has been noted before in previous Sriharikota launch coverage, Sri Lanka doesn't appear on the trajectory map.

So googled a map of sri lanka and the trajectory and it seems the vehicle passes over some part of northern sri lanka.The omission seems deliberate to avoid controversies.

The same is true for the other descending-node SSO launches from Sriharikota. I believe most or all launch threads here for previous Indian SSO launches have the NOTAMs mapped out.
