Global Navigation Satellite System (GNNS) Applications: Mapping & Tinning


Global Navigation Satellite System (GNSS) refers to a network of satellites that transmit signals allowing individuals to determine their exact location on Earth. GNSS applications include mapping and surveying, which involve creating detailed maps or diagrams of a specific area or site.

Mapping applications use GNSS technology to accurately locate and measure points on the Earth’s surface, creating a detailed digital map. These maps can be used for a variety of purposes, such as land management, navigation, and urban planning.

Surveying, also known as tinning, involves the precise measurement of land or structures for construction, engineering, or other purposes. GNSS technology allows surveyors to accurately determine the location, elevation, and orientation of points on the Earth’s surface.

Overall, GNSS applications such as mapping and surveying have greatly improved the accuracy and efficiency of land measurement and mapping, allowing for more precise and reliable data collection and analysis.

GNNS Applications: Mapping

Global Navigation Satellite Systems (GNSS) are used to determine the location, speed, and time of a device or vehicle by receiving signals from satellites in orbit around the Earth. Some of the main applications of GNSS in mapping include:

  1. Geodetic surveying: GNSS is used to measure the Earth’s shape, size, and orientation in space, as well as to determine the precise position of points on the Earth’s surface. This information is used to create accurate maps, measure land boundaries, and perform geodetic surveys.
  2. GIS mapping: GNSS is used to gather and analyze spatial data for geographic information systems (GIS). This includes mapping features such as roads, buildings, and natural features, as well as collecting data on land use, population, and other variables.
  3. Vehicle navigation: GNSS is used to provide real-time navigation information to drivers and pilots, including directions, traffic updates, and location-based services.
  4. Asset tracking: GNSS is used to track the location and movement of assets, such as vehicles, shipping containers, and equipment, in real-time. This information can be used to optimize routes, improve efficiency, and reduce costs.
  5. Disaster response: GNSS is used to map and assess the impact of natural disasters, such as earthquakes and floods, and to help coordinate rescue and recovery efforts.
  6. Agriculture: GNSS is used to map and monitor crops, soil conditions, and irrigation systems in precision agriculture applications. This can help farmers optimize crop yields and reduce the use of pesticides and fertilizers.

GNNS Application: Tinning

  1. Location tracking and navigation: Global Navigation Satellite Systems (GNSS) such as GPS, GLONASS, and Galileo allow devices to determine their location accurately and provide navigation services, allowing users to track their location or find directions to a desired location.
  2. Vehicle tracking and fleet management: GNSS can be used to track the location and movement of vehicles, allowing fleet managers to optimize routes and improve efficiency.
  3. Agriculture and precision farming: GNSS can be used to map and monitor crops, allowing farmers to optimize their use of resources such as fertilizers and pesticides.
  4. Disaster response and emergency services: GNSS can help emergency services locate and respond to incidents more quickly and efficiently.
  5. Environmental monitoring: GNSS can be used to track the movement of animals and monitor environmental factors such as air and water quality.
  6. Surveying and mapping: GNSS can be used to accurately measure distances and create detailed maps, allowing for more precise construction and land development.
  7. Geotagging and location-based services: GNSS can be used to add location data to photos, videos, and other media, allowing users to easily share their location and experiences with others.
  8. Military and defense: GNSS can be used for various military applications such as guiding missiles and providing location data for soldiers.


Global navigation satellite systems (GNSS) are used in a wide range of applications, including mapping and surveying. These systems utilize satellite signals to accurately determine the location and orientation of a device, allowing for the creation of precise maps and the identification of specific locations on the earth’s surface. GNSS applications have greatly improved the efficiency and accuracy of mapping and surveying tasks, and have become essential tools for many industries and government agencies. In conclusion, GNSS technologies have significantly impacted the fields of mapping and surveying, and will continue to play a vital role in these industries in the future.
