Detailed Description

@breif Reads NMEA GPS sentences from a UART serial port and prints parsed fix data.

Opens a serial connection to a GPS module wired to the jetson. Waits for GGA sentences, parses them with pynmea2 and prints timestamp, latitude, longitude, altitude, and satelite count.

Setupo

1. Enable serial port on the jetson:

   sudo systemctl disable nvgetty
   sudo systemctl stop nvgetty

2. Find which devide node the serial port maps to:

        ls -l /dev/serial0
   3.   Install dependencies
        @code
        pip install pyserial pynmea2

ser

gps-sensor-data.ser

Initial value:

=  serial.Serial(
    port='/dev/ttyTHS1',  # Adjust this for your specific setup
    baudrate=9600,
    parity=serial.PARITY_NONE,
    stopbits=serial.STOPBITS_ONE,
    bytesize=serial.EIGHTBITS,
    timeout=1  # Timeout in seconds
)

@breif Open and configure the serial connection to the GPS module.

Configure the serial port Replace '/dev/ttyS0' with the correct serial device name for your Pi (e.g., '/dev/ttyUSB0' for a USB-to-serial adapter) Ensure the baudrate matches the device you are communicating with.
