GPS Tracking System

Our project consists of three main components:

  1. TM4C123GH6PM microcontroller
  2. Ublox NEO-6m GPS Module
  3. Trajectory Plotter web python based app

Project features

  • serial watchdog with esp-32 to monitor the operations and easily debug code.
  • flask web server to update the location.
  • shortest path algorithm (A*) along with some other algorithms and structures.
  • lcd to print current latitude and longitude beside the accumulated traveled distance.

TODO

  • sensor fusion algorithm with IMU (gyro, accel, magnetometer) to compensate the considerable gps error, also it is a must in high speed scenarios like driving a car. The best and easy-to-implement algorithm is Extended Kalman filter.

  • implementing RTOS, the simplest algorithm is Round-Robin, which will prove beneficial in multi-sensor setup

  • implementing interrupt.

  • adding simple voice commands to direct the user towards the destination

  • correction methods for the distance function

idea of working

  • When the tiva lunch it first wait for the gps to receieve sentances displaying loading
  • when it starts working we use 
    SW1 ---> set the current location as the end point
SW2 ---> set the current location as the start point

Usage

LINUX platforms

  • First, download the tivaware (either the full SDK version or TM4c123gxl) from here, this step requires TI account.

  • Clone the project to your local machine

git clone https://github.com/mohamedrezk122/tivac-based-map-router

  • Follow this tutorial on how to setup lm4tools( for flashing binaries to the board), and tivaware.

  • Open terminal in project directory and execute the following commands

mkdir build
cmake ..
make 
sudo make flash
