GPS is primarily used to determine the precise location of an object on Earth's surface using signals transmitted from a constellation of satellites.

The United States Air Force is responsible for operating and maintaining the GPS system, ensuring its accuracy and reliability.

GPS operates by measuring the time it takes for signals to travel from a constellation of satellites to a receiver on Earth. This information is used to calculate the receiver's precise location.

The GPS constellation typically consists of 24 operational satellites, which are arranged in six orbital planes.

The process of determining a receiver's position using GPS signals is referred to as positioning.

GPS is used in various applications in Indian Geography, including mapping and surveying, navigation and tracking, and disaster management.

GPS enhances the accuracy of mapping and surveying by providing real-time location data, enabling precise measurement of distances and coordinates, and facilitating the creation of detailed topographic maps.

Andhra Pradesh was the first Indian state to implement a GPS-based land records system, known as the Andhra Pradesh Land Records Information System (APLRIS).

GPS offers accurate and real-time location information, enables efficient route planning and optimization, and facilitates seamless navigation across different terrains in Indian Geography.

Delhi was the first Indian city to implement a GPS-based public transportation system, known as the Delhi Integrated Multi-Modal Transit System (DIMTS).

GPS plays a crucial role in disaster management by assisting in tracking the movement of natural disasters, facilitating the coordination of relief efforts, and enabling the assessment of damage caused by disasters.

Maharashtra has the most extensive network of GPS-enabled weather stations in India, which aids in accurate weather forecasting and monitoring.

Differential GPS (DGPS), Real-Time Kinematic (RTK) GPS, and Wide Area Augmentation System (WAAS) are all techniques used to correct GPS signals and enhance their accuracy and reliability.

Rajasthan has implemented a GPS-based system for monitoring the movement of livestock, known as the Rajasthan Livestock Identification and Tracking System (RLITS).

GPS plays a significant role in the conservation of natural resources in Indian Geography by enabling the tracking of wildlife populations, facilitating the monitoring of forest cover and deforestation, and assisting in the management of water resources.
