// Initialize the GPS module
GPS gps = new GPS();while (true) {
// Read GPS data
String latitude = gps.getLatitude();
String longitude = gps.getLongitude();// Send GPS data to the cloud-based server
sendToServer(latitude, longitude);try {
Thread.sleep(10000); // Send data every 10 seconds
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}private static void sendToServer(String latitude, String longitude) {
try {
URL url = new URL("https://your-cloud-server.com/api/gps");
