## Experiment: Real-Time Display of GPS Position in Google Earth Visualize GPS data in real-time using Google Earth Pro. ![](https://cdn.shopify.com/s/files/1/0331/9994/7908/files/google-earth-pro.jpg?v=1754007284) **Background:** Google Earth Pro supports NMEA input via serial ports for dynamic tracking. **Setup:** - Use the serial communication code from previous experiments, but set baud rate to 4800 bps (Google Earth requirement). - Modify `Serial.begin(4800);` in setup. - Upload code, verify data in Serial Monitor, then close IDE to free the port. **Steps:** 1. Download Google Earth Pro (desktop version only; online lacks GPS support): [earth.google.com/earth-versions/earth-pro](https://www.google.com/earth/versions/earth-pro/). 2. Open Google Earth Pro > Tools > GPS > Select NMEA format > Start. 3. It auto-detects the serial port; position updates in real-time. ![](https://cdn.shopify.com/s/files/1/0331/9994/7908/files/google-earth-pro-01.png?v=1754007289) ![](https://cdn.shopify.com/s/files/1/0331/9994/7908/files/google-map_42ecb703-fd01-4189-8176-7c5afc7dc362.png?v=1754007294) **Results:** Map zooms to GPS location. **Tips:** Ensure clear sky; use a USB-to-serial adapter for direct PC connection if needed.
