ISRO To Launch Third Cartosat Satellite In Mid-DecemberThere will be a few foreign co-passenger satellites...about 15 to 20 (nano satellites)
Its rather intriguing why another Cartosat-2 series satellite was added later to the plan. Considering that the satellite is named 2ER and not 2F I wonder whether one of the earlier satellites met with an as yet undisclosed failure, or that they felt a need for an additional satellite in the fleet.
"We plan to launch Cartosat-2 series satellite 3 mission, which is a follow-on mission in the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imagery, in mid-December," the official said.
Where does it say that this satellite is Cartosat-2ER? The article saysQuote"We plan to launch Cartosat-2 series satellite 3 mission, which is a follow-on mission in the Cartosat-2 series with the primary objective of providing high-resolution scene specific spot imagery, in mid-December," the official said.There were three previous Cartosat-2 Series missions (Cartosat 2C, 2D and 2E), so I'm not sure why this one is called Satellite 3.
Where does it say that this satellite is Cartosat-2ER?

"In the next launch, we have a Cartosat along with 28 international commercial satellites, which we will launch in the second half of December," said S. Rakesh, the Chairman and Managing Director of Antrix Corporation Ltd, the commercial arm of state-run Indian Space Research Organisation (ISRO). There will be 25 nanosatellites and three microsatellites from the US and other countries as co-passengers along the space firm's own satellite of the Cartosat-2 series, he said. The satellites will be launched into the orbit onboard the Polar Satellite Launch Vehicle (PSLV), Rakesh added.

THIRUVANANTHAPURAM: After the recent failure of PSLV-C39 on August 31 this year, Isro centres here including VSSC and LPSC are doubly cautious. They are focused on the next mission of PSLV-C40 to launch 31 satellites including Cartosat -2ER by December end this year.Though PSLV-C40 was planned for launch in November end, it is now decided to launch by December end after a series of tests. "Preparations are on for the next mission of PSLV-C40 by next month end to launch 30 satellites at one go including the Cartosat-2ER satellite. It will be a robust launch," Vikram Sarabhai Space Centre (VSSC) director K Sivan had told TOI.
All precautions will be taken to prevent any anomalies, he said. In the previous PSLV launch, there was no design fault. The heat-shield at the top nozzle of the rocket failed to release the satellite into orbit and it could be due to a fault in pyro-techniques, he said.
Normally the heat shield split into two halves at the conical nozzle opens up to release the satellite into the orbit, it failed to open 20 minutes after lift-off, the scientist explained. The heat shield is designed to absorb excessive heat produced by friction against atmosphere during take-off and to protect the components and fuel tanks of the rocket.
"The reason why it failed could be due to some hitch in the pyrotechnic material of the heat shield or probably failure of the springs to trigger the force against atmosphere to open the shield to eject the satellite out. The exact reasons are being ascertained by the 'Failure Analysis Committee of core scientists and the report will be released soon, said a lead scientist at VSSC.While a VSSC scientist said, the failure analysis report is ready but it will be released only within the Isro centres. Based on its findings and recommendations all precautions will be taken to avert any failure, we are doubly cautious. A series of tests will be conducted before the next mission of PSLV-C40 slated for Dec end, he said.

And here's CARBONITE-2 in our cleanroom before ship out to launch site. CARBONITE-2 is a 100kg tech demo mission flying a COTS telescope & HD video to deliver 1m GSD images. @Earthi_
28 co-passengers (according to latest news):https://economictimes.indiatimes.com/news/science/india-to-launch-new-cartosat-2-28-foreign-satellites-in-december/articleshow/61344032.cms
They said most of the co-passengers of Cartosat-2 series satellite would commercial satellites from foreign countries, including Finland and the US.
The Finnish ICEYE-X1 satellite is ready, tested and has recently been shipped for launch! Radar imaging through clouds, through darkness. #eo #satellite #X1 headed for orbit -- soon!
