Space Communication System

A simulated space communication system demonstrating client-server architecture with error handling, packet transmission, and satellite communications.

Overview

This project simulates a space communication system between an Earth station (client) and a Satellite (server). It implements various networking concepts including:

• TCP/IP communication
• Packet transmission and acknowledgment
• Error detection and correction
• Signal interference simulation
• Logging and monitoring

Simulation Example

Network simulation showing packet flow between Earth station and Satellite

System Architecture

High-level architecture diagram of the communication system

Components

• earth_client.py - Earth station that sends messages
• satellite_server.py - Satellite server that receives transmissions
• utils.py - Utility functions for error handling and network operations
• logger_config.py - Logging configuration and setup
• satellite.py - Base satellite class implementation

Features

• Real-time signal strength visualization
• Packet acknowledgment system
• Automatic reconnection attempts
• Error detection using checksums
• Simulated atmospheric interference
• Comprehensive logging system

Requirements

• Python 3.6+
• Standard library modules (socket, json, logging)

Usage

1. Start the satellite server:

python satellite_server.py

2. Launch the earth client:

python earth_client.py

3. Follow the prompts to input the satellite server IP and message to transmit

Error Handling

The system includes:

• Packet corruption detection
• Automatic retransmission
• Connection loss recovery
• Timeout handling

Logging

All communications are logged to the logs directory with:

• Timestamp information
• Error reports
• Transmission status
• Signal quality metrics
