What is the total approved cost of the GalaxEye multisensor satellite project?

  1. A.Rs 147.69 crore
  2. B.Rs 247.69 crore
  3. C.Rs 347.69 crore
  4. D.Rs 447.69 crore

Correct answer

B. Rs 247.69 crore

Explanation

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.

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.

Q2.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.

Q3.Science & TechnologyHard

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
Show answer
Correct answer: C. 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…
