With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements:

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

Which of the statements given above is/are correct?

D.None
B.1 and 2 only
C.2 and 3 only
A.1 only

Correct Answer: Option A

The Indian Regional Navigation Satellite System (IRNSS), also known as NavIC, consists of a constellation of eight satellites.

Statement 1: Three satellites are positioned in geostationary orbit, and the remaining four are in geosynchronous orbits. Hence, statement 1 is correct.

Statement 2: NavIC's primary service area extends 1500 km beyond India's borders, not 5500 sq km. Hence, statement 2 is incorrect.

Statement 3: While there are long-term plans to expand NavIC's coverage, achieving full global coverage by 2019 was not feasible. Plans involve adding more satellites to the constellation. Hence, statement 3 is incorrect.
