Answer 1

The correct option is A Only 1 & 3

IRNSS system is similar to other satellite navigation systems like US’s GPS , Russia’s Glonass, Japan’s Quasi Zenith, Europe’s Galileo and China’s Beidou. It would provide two types of 24/7 standard services (i) Restricted Service (RS): an encrypted service provided to authorised users. It will be used for military and missile-related applications. (ii) Standard Positioning Service (SPS): to all users. The complete IRNSS system will include three satellites in geostationary orbit and four satellites in geosynchronous orbit at an altitude of 36,000 km above the Earth. IRNSS is a navigation system that will cover India, and also extend 1,500 kms from its boundaries.
Applications:

• Terrestrial, Aerial and Marine Navigation
• Disaster Management
• Vehicle tracking and fleet management
• Integration with mobile phones
• Precise Timing
• Mapping and Geodetic data capture
• Terrestrial navigation aid for hikers and travellers
• Visual and voice navigation for drivers.
