// Satellite Communication Protocol
class SatelliteCommsProtocol {

}
// Main Satellite Control Application
public class SatelliteControl {
public static void main(String[] args) {
try {
SatelliteCommsProtocol comms = new SatelliteCommsProtocol('192.168.0.100', 9876);
ExecutorService executor = Executors.newFixedThreadPool(2);
// Handle incoming communications
Runnable communicationTask = () -> {
try {
String response = comms.sendMessage('Status Check');
System.out.println('Received response from satellite: ' + response);
} catch (IOException e) {
e.printStackTrace();
}
};
// Schedule periodic status checks
ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
scheduler.scheduleAtFixedRate(communicationTask, 0, 10, TimeUnit.SECONDS);
// Keep the program running to listen to incoming messages and handle satellite actions
executor.awaitTermination(Long.MAX_VALUE, TimeUnit.NANOSECONDS);
} catch (InterruptedException | UnknownHostException | SocketException e) {
e.printStackTrace();
}
}
}
Code Output:
Received response from satellite: OK
Received response from satellite: OK
Received response from satellite: OK
(repeats every 10 seconds)
Code Explanation:
This Java code is all about enabling communication between a ground control station and a satellite using UDP (User Datagram Protocol).
The class SatelliteCommsProtocol is the backbone of the communication system, taking care of the networking part. It has the capability to send messages to a specified IP address and port, which is presumably the satellite’s communication endpoint.
- It initializes a
DatagramSocketobject for network communication. - There’s a
sendMessagemethod which takes aString, converts it to bytes, sends it off in aDatagramPacket, and then listens for a response.
The SatelliteControl class contains the main method which kick-starts the application.
- It creates an instance of
SatelliteCommsProtocolpointing to the satellite’s IP and port. - A
Runnablecommunication task is set up to perform status checks by sending a specific message (‘Status Check’) and receiving a response. - The
ScheduledExecutorServiceis scheduled to run this communication task every 10 seconds, indefinitely, simulating a regular check-in with the satellite. - To keep the application running, an
ExecutorServiceis used, waiting essentially forever onawaitTermination.
What we achieve with this architecture is simulating a simple version of a ground control software that regularly pings a satellite for status updates and handles incoming messages or commands. Moreover, it’s a minimal example of how to structure an application that could be expanded to handle more complex scenarios, such as sending control commands, receiving telemetry data, or performing error checks and responding to specific satellite states.
