Real-time International Space Station (ISS) Position Tracker with Deduplication
detail.loadingPreview
This n8n workflow automatically fetches the current position of the International Space Station (ISS) every minute. It intelligently filters new data points, ensuring only unique latitude, longitude, and timestamp information is processed, preventing redundant data.
About This Workflow
Ever wondered where the International Space Station is right now? This powerful n8n workflow provides a robust solution for real-time ISS position tracking and data collection. Running every minute, it connects directly to the wheretheiss.at API to retrieve the latest coordinates. What makes this workflow stand out is its integrated data deduplication logic. It intelligently stores previously seen timestamps and ensures that only genuinely new position updates are passed through, making your data streams efficient and clutter-free. Perfect for enthusiasts, data analysts, or anyone looking to integrate space data into their applications.
Key Features
- Automated Real-time Tracking: Automatically fetches the ISS position every minute using a Cron trigger.
- Direct API Integration: Seamlessly pulls live data from the
wheretheiss.atpublic API. - Intelligent Data Deduplication: Employs a Function node to store workflow-static data, ensuring only unique ISS position updates (based on timestamp) are processed, preventing redundant data.
- Clean Data Output: Provides filtered latitude, longitude, and timestamp, ready for further analysis or integration.
- Easy to Extend: The clean, filtered output can be easily connected to databases, notification services, or visualization tools.
How To Use
This workflow is designed for immediate use with minimal configuration.
- Deploy the Workflow: Import this JSON snippet into your n8n instance.
- Cron Node (
Cron): This node is pre-configured to run the workfloweveryMinute. No changes are typically needed here, but you can adjust the frequency if desired. - HTTP Request Node (
HTTP Request): This node is set up to call thehttps://api.wheretheiss.at/v1/satellites/25544/positionsAPI. It includes atimestampsquery parameter with={{Date.now();}}to fetch the most current data. No configuration is required. - Set Node (
Set): This node extractslatitude,longitude, andtimestampfrom the API response and ensures only these fields are passed to the next step. No configuration is required. - Function Node (
Function): This node contains the core logic for deduplication. It usesthis.getWorkflowStaticData("node")to store and compare timestamps, only returning data that hasn't been seen before. While pre-configured, you can extend this node to add more complex filtering or data manipulation if needed. For example, you could add logic to check if the ISS is over a specific region. - Connect to Your Desired Output: After the
Functionnode, connect subsequent nodes to utilize the filtered ISS position data. For instance, add a "Write to Google Sheets" node, a "Slack" node for notifications, or a "PostgreSQL" node for database storage.
