GPS/GNSS

  1. Q1 Mock Test 1, Q1

    Real-Time Kinematic (RTK) GNSS reaches centimetre-level accuracy in the field mainly because it:

    1. AUses signals of geostationary weather satellites in place of GPS
    2. BAverages code pseudoranges of a single receiver over a few seconds
    3. CApplies magnetic compass bearings to correct satellite positions
    4. DUses carrier-phase data with live corrections from a base station or CORS
    Show answerHide answer

    Answer D. Uses carrier-phase data with live corrections from a base station or CORS

    RTK resolves the carrier-phase ambiguity using corrections streamed from a reference station (or CORS network) a few km away, giving cm accuracy instantly; stand-alone code positioning gives only metre-level accuracy.

Astronomy

  1. Q2 Mock Test 1, Q2

    Comet 3I/ATLAS, which made its closest approach to Earth on 19 December 2025, is significant because it is:

    1. Athe third confirmed interstellar object observed passing through the Solar System
    2. Bthe first comet discovered by an Indian telescope
    3. Ca short-period comet returning after 76 years
    4. Da fragment of the Oort cloud captured into Earth orbit

    2. B22 GW
    3. C50 GW
    4. D500 GW
    Show answerHide answer

    Answer A. 100 GW

    India aims to reach 100 GW of nuclear capacity by 2047 using large reactors and small modular reactors; the SHANTI Act enables private participation towards this goal.
