Which of the statements given above is/are correct?

(a) 1 and 2 only (b) 1 , 2 and 3 only(c) 1, 2 and 4 only (d) All of the above

Answer : C

Explanation

An airborne early warning and control (AEW&C) system is an airborne radar system designed to detect aircraft, ships, vehicles, missiles, and other incoming projectiles at long ranges and perform command and control of the battlespace in an air engagement by directing fighter and attack aircraft strikes

he NATO E-3A (or AWACS) is a modified Boeing 707 equipped with long-range radar and passive sensors capable of detecting air and surface contacts over large distances. Information collected by AWACS can be transmitted directly from the aircraft to other users on land, at sea or in the air in near real time.

Question 3

3. It is fourth Indian navigation satellite.

4. IRNSS-1D will be launched into a sub Geosynchronous Transfer Orbit (sub GTO).

Which of the statements given above is/are correct?

(a) 1 and 2 only (b) 1 , 2 and 3 only(c) 1, 3 and 4 only (d) All of the above

Answer : c

Explanation

IRNSS 1 D was launched by Polar Satellite Launch Vehicle (PSLV) C-27. It is launched from Satish
Dhawan Space Centre, Sriharikota in Andhra Pradesh.

IRNSS-1D is a satellite in the Indian Regional Navigational Satellite System (IRNSS) constellation. The satellite is the fourth of seven in the constellation, launched after IRNSS-1A, IRNSS-1B and IRNSS-1C.

The satellite is the only satellite in the constellation slated to provide navigational services to the region.

The satellite will be placed in geosynchronous orbit.

It was launched successfully on 28 March 2015 onboard ISRO’s PSLV-C27 from Satish Dhawan Space Center, Sriharikota
