Correct Answer - Option 2 : NAVIC
Explanation:
NAVIC:
The Indian Regional Navigation Satellite System, with an operational name of NavIC, is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km around it, with plans for further extension.
- It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area.
- An Extended Service Area lies between the primary service area and the area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.
- IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users, and Restricted Service (RS), which is an encrypted service provided only to the authorized users.
- The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area.
Some applications of IRNSS are:
- 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 travelers
- Visual and voice navigation for drivers
The IRNSS Signal-in-Space Interface Control Document for Standard Positioning Service (SPS) is released to the public to provide the essential information on the IRNSS signal-in-space, to facilitate research & development, and aid the commercial use of the IRNSS signals for navigation-based applications.

The Global Positioning System, originally Navstar GPS, is a satellite-based radio navigation system owned by the United States government and operated by the United States Space Force.
- The BeiDou Navigation Satellite System is a Chinese satellite navigation system. It consists of two separate satellite constellations i.e. BeiDou-1 and BeiDou-2.
-
GLONASS, or "Global Navigation Satellite System", is a space-based satellite navigation system operating as part of a radio navigation-satellite service. It provides an alternative to GPS and is the second navigational system in operation with global coverage and of comparable precision.
