The RDI support is meant to take the OptoSAR technology through which readiness levels?

  1. A.TRL-1 to TRL-4
  2. B.TRL-3 to TRL-6
  3. C.TRL-6 to TRL-9
  4. D.TRL-4 to TRL-7

Correct answer

C. TRL-6 to TRL-9

Explanation

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.

Q1.Science & TechnologyMedium

How much support has the Technology Development Board agreed to give GalaxEye under the RDI Fund?

  1. A.Rs 36.48 crore
  2. B.Rs 63.84 crore
  3. C.Rs 84.63 crore
  4. D.Rs 127.50 crore
Show answer
Correct answer: B. Rs 63.84 crore

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.

Q3.Science & TechnologyEasy

The OptoSAR technology of GalaxEye brings together which two kinds of imaging?

  1. A.Synthetic Aperture Radar and electro-optical imaging
  2. B.LiDAR and thermal infrared imaging
  3. C.Hyperspectral imaging and radar altimetry
  4. D.Satellite navigation signals and sonar imaging
Show answer
Correct answer: A. Synthetic Aperture Radar and electro-optical imaging

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.
