31. With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements: [I.A.S. (Pre) 2018]

IRNSS has three satellites in geostationary and four satellites in geosynchronous orbits.
IRNSS covers entire India and about 5500 sq. km beyond its borders.
India will have its own satellite navigation system with full global coverage by the middle of 2019.

Which of the statements given above is/are correct?

(a) 1 only
(b) 1 and 2 only
(c) 2 and 3 only
(d) None

Correct Answer: (a) 1 only

Solution:

The Indian Regional Navigation Satellite System (IRNSS), named by P.M. Modi as NavIC (Navigation with Indian Constellation), is a regional satellite navigation system that provides accurate real-time positioning and timing services covering India and a region extending to 1500 km around. In IRNSS, out of seven satellites of the constellation, three satellites were deployed in geostationary orbit and four satellites were placed in geosynchronous orbit. There is no proposed plan to extend it throughout the world. Thus, only statement 1 is correct.

Correct Answer: (b) Navigation with Indian Constellation

Solution:

The Indian Regional Navigation Satellite System (IRNSS), named by P.M. Modi as NavIC (Navigation with Indian Constellation).

(a) Greenwich Polar Satellite
(b) Global Police Surveillance
(c) Global Positioning System
(d) General Pacific Survey

Correct Answer: (c) Global Positioning System

Solution:GPS means Global Positioning System, a space-based navigation system. It was developed by the U.S. Department of Defense. It became fully operational from 27th April 1995.

36. In which of the following areas can GPS technology be used? [I.A.S. (Pre) 2018]

Mobile phone operations
Banking operations
Controlling the power grids

Select the correct answer using the codes given below:

(a) 1 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2, and 3

Correct Answer: (d) 1, 2, and 3

Solution:The Global Positioning System (GPS) is a satellite-based radio navigation system that provides geo-location and time information to a GPS receiver anywhere on or near the Earth. GPS technology is now in everything from cellphones and wristwatches to bulldozers, shipping containers, and ATMs. Major communication networks, banking systems, financial markets, and power grids depend heavily on GPS for precise time synchronization.

37. India developed the Satellite launch vehicles over a period of a few decades. Which is the correct chronological order of development of the following vehicles A, B, C, and D? [U.P.P.C.S. (Mains) 2004]

B. ASLV
C. SLV
D. GSLV

Code:

(a) A, B, C, D
(b) B, C, D, A
(c) D, C, A, B
(d) C, B, A, D

Correct Answer: (d) C, B, A, D

Solution:The correct chronological order of development of the above satellite launch vehicles are:
SLV - August 10, 1979
ASLV - March 24, 1987
PSLV - September 20, 1993
GSLV - April 18, 2001

38. Match the following pairs: [R.A.S/R.T.S. (Pre) 2016]

Launch Vehicle	Satellite

(ii) Augmented Satellite Launch Vehicle (ASLV)	B. Rohini
(iii) Polar Satellite Launch Vehicle (PSLV)	C. SROSS-C
(iv) Geosynchronous Satellite Launch Vehicle (GSLV)	D. EDUSAT

Which of the following codes are correctly matched?

(a) A - B - C - D
(b) B - C - D - A
(c) B - C - A - D
(d) C - B - A - D

Correct Answer: (c) B - C - A - D

(C)	B	C	A	D
(d)	C	B	A	D

SLV-3 was successfully launched on July 18, 1980 when Rohini satellite, RS-1 was placed in the orbit, thereby making India the sixth member of an exclusive club of space-faring nations. The Augmented Satellite Launch Vehicle (ASLV) programme was designed to augment the payload capacity to 150 kg, thrice that of SLV-3 for low earth orbits. The third developmental flight ASLV-D3 was successfully launched on May 20, 1992, when SROSS-C (106 kg) was put into the orbit of 225 x 430 km. PSLV is one of the world's most reliable launch vehicles. It has been in service for twenty years and has launched various satellites for historic missions like Chandrayaan-1, Mars Orbiter Mission, Indian Regional Navigation Satellite System (IRNSS), etc. The Geosynchronous Satellite Launch Vehicle (GSLV) was primarily developed to launch INSAT/GSAT class of satellites into orbit. GSLV is being used for launching GSAT series of satellites. GSLV has launched various communication satellites, among which EDUSAT is notable, being India's first dedicated educational satellite. GSLV-MKIII (LVM3) has launched Chandrayaan-2 and Chandrayaan-3.
