    I have no idea why you guys keep coming into my threads to claim things that are not true. In the major Indian forums, you are free to claim whatever you want. I don't bother you there. I have this little corner in the Chinese sub-forum. When you make a claim that is flat-out untrue, I have to...

    The sensor is not Indian. That fact will never change.

    No. The CCD sensor is imported. Thus, the most important part of your satellite is foreign. It is foreign technology. Without the foreign electronics and semiconductor chips, you don't have an imaging satellite. India gets no credit for buying foreign technology. "RISAT-2's main sensor is an...

    Mars Orbiter was due to NASA's experience and NASA's Deep Space Network. None of it was Indian. NASA has decades of experience in launching Mars missions. India has none. The flight was a success. That was no surprise. NASA has been doing it for decades. India could not communicate with a Mars...

    That's my point. Israel licenses American technology (from America's spy satellite programs) and sold a variant to India. The most critical piece of an imaging satellite is the advanced sensors and it is western as I have said all along. Without the advanced sensors, what do you have? Nothing...

    Give me a break. India launches ridiculously useless satellites that weigh a few pounds each. What can you do with 104 tiny Indian satellites? Nothing. China launches DFH-4 telecommunication satellites that each weigh 10,000 pounds and last 15 years in orbit. China's DFH-4 satellite has a...

    At the micron level, not at the nanometer level. India is about 10 to 20 years behind the rest of the world. Also, that is only a research lab and has never produced chips for commercial use.

    Satellite sensors are based on semiconductors and electronics. China's most advanced semiconductor fabrication plant is run by SMIC, which produces advanced semiconductors with 28nm width. India has no commercial semiconductor plants. Since India does not produce any modern semiconductors...

    No. The sensor is imported western electronics. Assembling together a bunch of western sensors does not make it an INDIGENOUS Indian satellite. It is merely a screwdriver-ed western satellite. This is not that hard to understand. India's heavy-launch rocket uses Russian rocket engines. It is...

    Those are imported western sensors. India has no indigenous semiconductor fabrication plant capable of manufacturing modern sensors.

    How much do countries invest in R&D? New UNESCO data tool reveals emerging players "China’s R&D spending only amounts to 2% of its GDP, but this means that the country is pouring about PPP$369 billion into this sector each year. As the share of global R&D expenditure by high-income countries...

    I want to make it clear that this problem of claiming credit for other people's technology is not limited to India. Japan imports American turbofan engines and they give you the impression that the F-2 fighter is indigenous. The Japanese F-2 fighter is imported American technology. Japan has...

    The Chinese SAR satellite provides black-and-white images in one meter. Western SAR satellites provide color images in one meter. China slowly climbs the technological ladder with indigenous invention. Other countries buy from the West and claim the technology as their own. This is silly. The...

    Let's use common sense. When India buys a TESLA, does that mean India owns TESLA technology? No, India can't built a TESLA electric vehicle. Similarly, India bought an American SAR satellite. Does that mean India possesses SAR satellite technology? No. It only means you bought American technology.

    China's SAR satellite technology is indigenous. China deserves credit for building INDIGENOUS advanced technology. You can trace all Chinese technologies from primitive prototypes all of the way to advanced state-of-the-art mature technologies. On the other hand, some countries import US...

    Why are you showing me pictures of a satellite built from foreign parts? India does not build semiconductors and all of the sensors on the so-called "Indian" SAR satellite was imported from the West. The technology and the components of the "Indian" SAR satellite were both imported.

    China's Gaofen-3 SAR satellite was built by China. India's SAR satellite was built by NASA in the US. Not the same thing. "The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO."

    China released pictures from its "first high-resolution Synthetic Aperture Radar (SAR) [Gaofen-3] satellite." The resolution is one meter. Interestingly, a more advanced Gaofen-5 satellite is scheduled for launch in six months. "Gaofen-5 hyerspectral satellite is planned to be launched in...
