Realization of a drone tracking system 

What is GPS ?

The Global Positioning System (GPS) is a navigation system using satellites, a receiver and algorithms to synchronize location, velocity and time data for air, sea and land travel .

1/ Hardware used :

NEO-6M GPS module :

The NEO-6M GPS module has four pins: VCC, RX, TX, and GND. The module communicates with the stm32 via serial communication using the TX and RX pins ,So , the GPS module transmits the data via the UART* in the NMEA *format . 

 Nucleo l476rg :

           

2/ CubeMX Setup  :

* UART configuration :

the UART Baud Rate is configured at 9600 bps. This is according to the Neo 6M .

Eanable the  UART interrupt  .

2/ the Code :    

• A simple C library (STM32 HAL) for working with the GPS module NEO-6M  : https://ru.aliexpress.com/wholesale?trafficChannel=main&d=y&CatId=0&SearchText=neo-6m&ltype=wholesale&SortType=total_tranpro_desc&groupsort=1&page=1

• Copy the library header and source file to the appropriate project directories (Inc, Src) .
• Config the GPS module UART  on gps.h file

• In the head file of the project (main.c), include the header file

• add UART call back

• add in main function section for initial initialization of the GPS module NEO-6M
