3. INTRODUCTION The Global Positioning System (GPS) is a satellite-based navigation system that allows users to determine their precise location on Earth. It consists of a network of at least 24 satellites that orbit the planet, continuously transmitting signals. GPS receivers use these signals to calculate their position through a process called triangulation. The system provides accurate information about latitude, longitude, and altitude. GPS is widely used in various applications, including navigation, mapping, and location-based services.

4. Circuit Diagram There are so many GPS tracking systems are available…..

5. Users Elderly people with memory loss problems. Some parents will use it for neuro- typically children. There is also need in other countries. Other possible uses for GPS tracking device- cars, teenagers, etc. or wear it as a bracelet.

8. Advantages Cost-Effective : Low operational costs compared to other tracking systems. User-Friendly : Easy to use with various applications and devices. Integration : Can be integrated with other technologies for enhanced functionality. Emergency Response : Enhances response times for emergency services by pinpointing locations. Navigation : Assists in route planning and navigation, reducing travel time. Real-Time Tracking : Enables live tracking of vehicles, assets, and individuals.

9. GPS Location Tracker Working GPS is basically based on the time and known positions of the satellites. The satellites use ultra-precise atomic clocks to synchronize with each other and also to the receivers on the earth. How GPS works- The satellites transmits radio signals at regular intervals carrying information. This information is about the time and it’s location at the point in time. The receiver has to monitor information form multiple satellites to calculate and identify the precise location. For this purpose, at least 4 satellites have to be in the viewing field to the receiver.

10. GPS Location Tracker Segments

11. GPS System Segments Space Segment:- It is the constellation of satellites which moves in a circular orbit around the earth. It is also called satellite segment. Control Segment:- Using the control segment we can monitor and control stations on the ground to catch the radio signals sent by the various satellites. User Segment:- The user segment is the receiver that uses the transmitted data to estimate the precise location of the user. The number of satellites it can monitor simultaneously defines the user’s capability.

12. Accuracy: While GPS can typically provide accuracy within a few meters, factors like signal interference, satellite geometry, and atmospheric conditions can affect precision. Advanced techniques can improve accuracy even further.

13. Applications Asset Tracking Ambulance Tracking and Emergency Medical Services Fleet GPS Wildlife Tracking Anti Hijack and Vehicle Security System Adventure/ Travelling GPS bracelet locate people

14. Future Scope Better Accuracy: New technologies will make GPS even more precise, helping things like self-driving cars and farming equipment know their exact location. Stronger Systems: New tools and backup systems will make GPS more reliable, reducing issues caused by interference or signal loss. Tracking the Environment: GPS will be used to monitor changes in nature, helping with things like disaster response and managing resources more effectively.
