Personal Navigation System

Overview

This personal navigation system utilizes GPS technology to provide real-time location tracking and navigation assistance. It has USB satellite receiver support for real time updates. You can view the design document here.

Technologies Used

• Java Programming: JavaFX & Swing, Object-oriented Programming
• GPS Technology: Integration with satellites, real-time location tracking, GPGGA sentences
• Data Structures: Graphs, trees, and algorithms (Dijkstra's and Bellman-Ford) for pathfinding
• Hardware: Integration with GPS receivers

The Product

The Navigation System is a Java-based application designed to provide real-time GPS navigation and mapping services.

It features a user-friendly interface that allows users to input destinations and receive directions.

The system utilizes GPS satellite technology to track the user's location and provide accurate navigation instructions.

It also includes features such as route-relocation.

The GIF is a very simple demonstration of the system's capabilities in real-time navigation and mapping.

Challenges & Solutions

Going into this project, I knew nothing about the world of GPS technology and real-time navigation systems. I had to learn everything about this subject while also figuring out how to program it at the same time.

The biggest challenge I faced was system optimization. A GPS system must process location data quickly and efficiently to provide real-time updates to users. I had to learn about algorithms for pathfinding and how to manage data from multiple sources.

Takeaways

This project taught me the importance of understanding both the hardware and software aspects of GPS technology. I learned how to effectively integrate these components to create a functional navigation system.

Working on this project also improved my skills in Java programming, particularly in GUI development and real-time data processing. Threading was also a key aspect, as it allowed for smoother user interactions and more responsive updates.

Additionally, I gained insights into design patterns that are crucial for building scalable and maintainable software. Understanding patterns such as Model-View-Controller (MVC), Observer, and Strategy helped me structure the application more effectively.

Some key takeaways include:

• Improving my skills in Java programming and GUI development.
• Understanding the systems behind navigation systems.
• Gaining experience in optimizing algorithms for efficient pathfinding and navigation.
