Consider the following statements, with reference to the Indian Region...
Both Statement 1 and 2 are correct: NavIC is better than GPS in some aspects. While GPS can get you within 20 metres of your target, NaVIC is more accurate and can get you even closer—within 5 metres.
- For individual users, this might not be significant but for military equipment like guided missiles, it is crucial.
- However, unlike GPS, which can be used anywhere in the world, NaVIC is regional and can only be used within India and up to 1,500 km from its borders.
- NavIC uses satellites in high geo-stationery orbit — the satellites move at a constant speed relative to Earth, so they are always looking over the same region on Earth.
- NavIC signals come to India at a 90-degree angle, making it easier for them to reach devices located even in congested areas, dense forests, or mountains.

Consider the following statements, with reference to the Indian Region...
NavIC (Indian Regional Navigation Satellite System)
Statement 1: NavIC signals come to India at a 90-degree angle.
This statement is incorrect.
NavIC is the Indian Regional Navigation Satellite System developed by the Indian Space Research Organisation (ISRO). It consists of a constellation of satellites in geosynchronous and geostationary orbits to provide precise positioning and timing information for users in the Indian region. The satellites in the NavIC constellation are positioned in geostationary orbits, which means they appear to be stationary relative to the Earth's surface.
Since the NavIC satellites are in geostationary orbits, the signals they transmit reach the Earth's surface at a very shallow angle, not at a 90-degree angle. The satellites are positioned above a specific location on the equator, where their orbital speed matches the rotation of the Earth, allowing them to remain fixed relative to the Earth's surface.
Statement 2: It can reach devices located even in congested areas, dense forests, or mountains.
This statement is correct.
One of the advantages of the NavIC system is its ability to provide positioning and timing information in challenging environments such as congested areas, dense forests, or mountains. The NavIC signals have a better penetration capability compared to other global navigation satellite systems, such as GPS.
The NavIC signals have a higher power level and operate in the L5 frequency band, which allows them to penetrate through obstacles like buildings, vegetation, or terrain. This makes NavIC particularly useful in urban areas with tall buildings or in regions with dense foliage. Users in such areas can still receive accurate positioning and timing information from the NavIC system.
Additionally, NavIC provides a high level of accuracy, with a position error of less than 5 meters for the standard positioning service. This level of accuracy is beneficial for various applications, including navigation, surveying, agriculture, disaster management, and personal tracking.
In conclusion, statement 1 is incorrect as NavIC signals do not come to India at a 90-degree angle. However, statement 2 is correct as NavIC can reach devices located even in congested areas, dense forests, or mountains due to its better penetration capability and high accuracy.
