A potential payload for PSLV C42 is SSTL-S1, a 450 kg Earth observation satellite  manufatured and owned by SSTL for Chinese private company 21AT Co. Ltd (via reddit)

The satellite will be launched on the Indian Space Research Organisation's Polar rocket in August.

NovaSAR-S could also be a co-passenger on this flight. It was supposed to be launched on board C40 mission in January but was delayed for some reason.

NovaSAR-S details:

Mass: 430 kg
Manufacturer: SSTL
Country: UK
Payload: SAR

“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.

Quote
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.

According to this article PSLV C-42 will have 25-30 small satelites onboard with total mass of around 250 kg as well as a primary payload from isro with mass of 800-1000 kg.

I would not be surprised if ISRO decides at the last minute to launch a Cartosat 2G instead of Cartosat 3.

From this article the nominees for this launch are

Cartosat 3
Oceansat 3
RISAT 1A

https://www.hindustantimes.com/science/chandrayaan-2-oceansat-3-isro-s-launch-plans-in-2018/story-KEZikZnvCSSvgARD9Y59QN.html

We can rule out RISAT-1A due to the lift off mass of 1858kg. The article says primary payload will be between 800-1000 kg. 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.

I'm willing to bet the primary payload are two commercial 450 kg satelites (SSTL-S1 and novasar-s) or some satelites we dont know about that isro has in development.

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.

Looks like Centauri I from Fleet is flying on this mission.

http://www.manmonthly.com.au/news/fleet-space-technologies-unveils-launch-partners-first-nanosatellite-launches/

Australian Internet of Things (IoT) startup, Fleet Space Technologies, has today announced launch plans for its first two nanosatellites, Centauri I and II, in 2018.

Fleet Space Technologies has announced that the first of its nanosatellites is under contract to launch with Spaceflight aboard an Indian Polar Satellite Launch Vehicle (PSLV) by Antrix/ISRO. This satellite will establish a global network that will connect the world’s sensors and devices, for free. Just one satellite has the ability to cover 90% of the Earth.

ISAC manifest attached. Note that the quarter dates are based on indian financial year which begins in april and ends in march of next year. So Q3 would indicate a time somewhere September - December

Thanks K210! Perhaps the ISRO payload is EMISAT, which was scheduled to be available in the first quarter of 2018.

At about 400 kg, that still falls short of the 800-1000 kg description.

As the Commission is aware, BlackSky is under a tight timetable to ship its
Global-1 satellite on July 15, 2018, for a September launch.

Global-1 is on a PSLV flight.
Does this mean that PSLV C42 launch date is pushed to the right into September?

Presumably. Strange that ISRO hasn't listed this mission on their website.

The "ISRO EO sat" will be HySIS, Hyperspectral Imaging Satellite

and 30 foreign commercial co-passengers will be onboard

Probably PSLV-XL.

ISRO to develop full-fledged hyperspectral imaging satellite

Quote
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.

Quote
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.

Quote
'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.

Quote
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.

A slew of satellites are expected to be launched by ISRO after a dull year of launch mission.

Quote
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.
