TDB Gives GalaxEye Rs 63.84 Crore for OptoSAR Satellite

The correct answer is Rs 63.84 crore, the financial support agreed under the Research Development and Innovation Fund and routed through optionally convertible debentures rather than paid out as a simple grant. Keep it apart from the other money figure in the same announcement, the total approved cost of the project, which is far larger; a question will often place the two side by side to see whether a candidate has confused the support with the whole outlay. Options A and C are the same digits rearranged, a trap that works precisely because the figure carries two decimal places and is easy to garble under time pressure. Option D is a round-looking amount that appears nowhere in the announcement. The safest habit is to read such a figure once as a whole number of crore and once as its decimal part.

The correct answer is Rs 247.69 crore. This is the approved cost of the whole project, of which the Technology Development Board is supporting a part from the Research Development and Innovation Fund, the rest being borne by the company. The distinction matters because a public fund of this kind is meant to share the risk of a costly technology programme rather than to pay for it outright, which is also why the support takes the form of optionally convertible debentures. Options A, C and D keep the decimal part and change only the leading digit, so a candidate who has memorised the figure loosely will not be able to separate them. Pair the two numbers in your notes as support and total cost, and the pair becomes easier to recall than either figure on its own.

The correct answer is Synthetic Aperture Radar and electro-optical imaging, and the name of the technology is itself the clue, since Opto stands for the optical sensor and SAR for the radar. The two are put on one platform because their weaknesses do not overlap: optical imaging gives rich visual detail but is defeated by cloud cover and by darkness, while radar works irrespective of daylight and can image through cloud. Fusing the two data streams therefore yields a fuller and less interrupted view of the ground, which is what makes wide-area surveillance, detection of people and vehicles and classification of targets possible in all weather. Options B, C and D list real remote-sensing techniques, but none of them is the pair named here, and option D also includes sonar, which works in water rather than from orbit.

The correct answer is TRL-6 to TRL-9. Technology Readiness Level is a scale for how far a technology has travelled from an idea towards routine use, and the stretch named here is the late one: a system already demonstrated in conditions close to the real environment has to be engineered, tested and validated until it is proven in actual service. The Board describes its role in exactly those terms, as support through the critical stages between advanced development and deployment, with commercialisation as the eventual aim. Options A and B describe earlier stages, where the work is closer to laboratory research than to flight hardware, and a candidate who assumes that public funding always goes to early research will be drawn to them. Option D stops short of the top of the scale and so does not match the stated goal of reaching deployment.
