Q1Consider the following statements: 1. NavIC's coverage area includes India and a region up to 1500 km beyond the Indian boundary. 2. ISRO and the Airports Authority of India implemented GAGAN as a satellite based augmentation system for Indian airspace. 3. GAGAN is described by ISRO as India's independent regional navigation constellation. 4. NavIC provides only one user service, the Restricted Service. Which of the statements given above are correct?
Statements 1 and 2 are correct. Statement 3 is false because GAGAN is an augmentation system, while NavIC is the independent regional navigation system. Statement 4 is false because NavIC has two services, SPS and RS.
Q2Consider the following statements about the NavIC constellation: 1. NavIC is designed with a constellation of 7 satellites. 2. Three NavIC satellites are placed in geostationary orbit. 3. All seven NavIC satellites are placed in low Earth orbit. Which of the statements given above are correct?
Statements 1 and 2 are correct: ISRO states that NavIC is designed as a 7-satellite constellation and that three satellites are in geostationary orbit. Statement 3 is false because the cited design uses geostationary and inclined geosynchronous orbits, not low Earth orbit for all satellites.
Q3Consider the following statements: 1. NavIC offers only a restricted service and has no civilian positioning service. 2. NavIC provides a Standard Position Service for civilian users and a Restricted Service for strategic users. 3. NavIC services are provided only in the C band. Which of the statements given above are correct?
Statement 1 is false because NavIC has a civilian Standard Position Service. Statement 2 is correct. Statement 3 is false: ISRO states that these services are provided in L5 and S bands, not only in C band.
Q4Consider the following statements: 1. In NavIC, all satellites are placed in low Earth orbit. 2. NavIC coverage includes India and a region up to 1500 km beyond the Indian boundary. 3. NavIC services are provided only in the L1 band. Which of the statements given above are correct?
Statement 1 is false: ISRO says NavIC uses geostationary and inclined geosynchronous orbits. Statement 2 is true because ISRO defines the coverage as India plus 1500 km beyond the Indian boundary. Statement 3 is false: the cited service bands are L5 and S, with L1 being introduced for forthcoming satellites.
Q5Consider the following statements: 1. The Indian Mission Control Centre for satellite-aided search and rescue is located at Sriharikota. 2. The objective of the COSPAS-SARSAT system is to reduce the delay or time required to locate distress alerts and provide assistance. 3. ISRO says the Indian satellite-aided search and rescue system has been operational only since 2000. Which of the statements given above are correct?
Statement 1 is false because INMCC is located at ISTRAC, Bangalore. Statement 2 is correct. Statement 3 is false because ISRO says the system has been operational since 1989-90, not only since 2000.
