Off the top of my head:

1) Highly agile/steerable antennas. Can image a "location of interest" for longer and from multiple angles
2) Multispectral imaging
3) 0.25 cm images in panchromatic and 1 m resolution in multispectral imagery

Overall, a very sophisticated satellite, the first in its series

There may be a typo .. image resolution could be around 0.25 meters (or 25 cm). May like to edit the statement.

****
This corresponds to theoretical limit for 1 m optics. ( 500 x10^3 m/0.25 m = 2*10^6, so if wavelength = 500 nm, you need 1 meter objective)

In photos: The scientists who launched India’s space programme
By Manavi Kapur October 11, 2019


Image
Homi Bhabha (glass in one hand) showing prime minister Jawaharlal Nehru (extreme left) the model of the Tata Institute of Fundamental Research. To Nehru’s left is SS Bhatnagar; to Bhabha’s left is Morarji Desai, who later became the prime minister of India in 1977. Between Bhabha and Desai, in the background, is MC Chagla, the eminent jurist and diplomat.


Image
Some of the early recruits of Sarabhai’s were trained by NASA at its Wallops station in Virginia. In this picture, they are familiarising themselves with the operation of the Kodak K-24 aerial camera suitably modified for vapour trail photography with custom-made mountings.

Image
NASA also supplied Nike-Apache sounding rockets (including the one for the inaugural flight) and some tracking equipment. Note the bicycle in the background; it was the only readily available mode of transport in Thumba Equatorial Rocket Launching Station, in Kerala, in the 1960s.

Image
The very first rocket flight from Thumba was watched by boy scouts, among others.

Image
D Bhavsar (right), the project director for the first sodium vapour cloud experiment, watching for the release of the vapour.

Image
The very first indigenous rocket made by ISRO was known as RH-75 (RH stands for Rohini and 75 refers to the diameter of the rocket in mm). It was made from readily available extruded aluminium alloy tubes from the market. YJ Rao (with spectacles) is showing Sarabhai the RH-75.

Image
Sarabhai, the newly appointed chairman of the Atomic Energy Commission, addressing employees of the Atomic Energy Establishment gathered to condole the death of Homi Bhabha, who was killed in an air crash on Mont Blanc on Jan. 24, 1966.


Image
On Feb. 2, 1968, then prime minister Indira Gandhi dedicated Thumba Equatorial Rocket Launching Station to the United Nations.


Image
This photograph of the rocket nose cone on a bicycle taken by Henri Cartier-Bresson is by now famous. On the right: engineer, CR Sathya. His assistant, Velappan Nair, is taking care of the nose cone.


Image
Sarabhai and then prime minister Indira Gandhi with a farmer during the inauguration of Krishi Darshan, a TV programme meant exclusively for farmers. Sarabhai conceived of this programme to convince the government that TV could be used to inform farmers of the latest developments in agriculture.

We are considering buying a Unidirectional shotgun mic and mount it on a boom to record the roar of the rocket minimising the noise as much as possible

I remember the Vikram processor being on board a PSLV in Sept/2009( carrying Oceansat-2). Was that a different version of the Vikram chip, or the same, but actually fabricated elsewhere( i.e Taiwan, S.Korea), and designed by ISRO.

Vikram Lander Found

Image

Image

The Chandrayaan 2 Vikram lander was targeted for a highland smooth plain about 600 kilometers from the south pole; unfortunately the Indian Space Research Organisation (ISRO) lost contact with their lander shortly before the scheduled touchdown (7 September in India, 6th September in the United States). Despite the loss, getting that close to the surface was an amazing achievement. The LROC team released the first mosaic (acquired 17 September) of the site on 26 September and many people have downloaded the mosaic to search for signs of Vikram. Shanmuga Subramanian contacted the LRO project with a positive identification of debris. After receiving this tip the LROC team confirmed the identification by comparing before and after images. When the images for the first mosaic were acquired the impact point was poorly illuminated and thus not easily identifiable. Two subsequent image sequences were acquired on 14, 15 October and 11 November. The LROC team scoured the surrounding area in these new mosaics and found the impact site (70.8810°S, 22.7840°E, 834 m elevation) and associated debris field. The November mosaic had the best pixel scale (0.7 meter) and lighting conditions (72° incidence angle).

The debris first located by Shanmuga is about 750 meters northwest of the main crash site and was a single bright pixel identification in that first mosaic (1.3 meter pixels, 84° incidence angle). The November mosaic shows best the impact crater, ray and extensive debris field. The three largest pieces of debris are each about 2x2 pixels and cast a one pixel shadow.

ISRO to launch surveillance satellite on Dec 11.

India will put into orbit another of its sharp-eyed surveillance satellite RISAT-2BR1 with synthetic aperture radar on December 11, an Indian space agency official said on Tuesday.

"The next space mission is to orbit RISAT-2BR1, a radar imaging satellite. The rocket launch will be on December 11," an official of the Indian Space Research Organisation (ISRO), who spoke on the condition of anonymity, told IANS.

Piggy backing on the 615 kg RISAT-2BR1 in the Polar Satellite Launch vehicle would be four foreign satellites that India will be carrying for a fee.

According to the official, another radar imaging satellite 2BR2 with synthetic aperture radar will soon follow after December 11 mission.

A clutch of such sharp-eyed satellites are necessary to look down at the earth on a continuous basis. In May this year, ISRO had launched 615 kg RISAT-2B.

News reports say that the RISAT-2BR series are a more sophisticated version of TECSAR1 (from Israel, which was named RISAT-2). Much better resolution (0.35 m)

https://www.moneycontrol.com/news/science/isro-to-launch-second-spy-satellite-risat-2br1-on-december-11-to-enhance-indias-surveillance-capability-4695061.html

I hope we are using the humongous amount of data from these satellites to perfect AI/ML algorithms to detect aberrations, auto-classify objects, flag threats etc. Its a treasure trove of data to build next-gen AI systems and to train an army of math & comp-sci techies. Can spin-off many startups & commercial products

Some changes/ surprises already to the Dec 11 launch- 4 strap-ons, 9 customer satellites instead of the previously announced 4, and 628kg for RISAT-2BR1( as opposed to 615kg, no big deal, still..)

https://www.isro.gov.in/launcher/pslv-c48-risat-2br1

PSLV-C48 is scheduled to launch RISAT-2BR1 and 9 commercial satellites on December 11, 2019 from Satish Dhawan Space Centre SHAR

PSLV-C48, which is the 50th mission of PSLV, will launch RISAT-2BR1 from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. The launch is tentatively scheduled at 1525 Hrs IST on December 11, 2019, subject to weather conditions.

RISAT-2BR1, a Radar imaging earth observation satellite weighing about 628 kg, will be placed into an orbit of 576 km at an inclination of 37 degree.

PSLV-C48 will also carry 9 customer sa...
