Automated Collection and Storage of International Space Station Trajectory Data
Key Features and Highlights
This workflow periodically calls the International Space Station (ISS) location API to obtain real-time latitude, longitude, and timestamp data of the space station, automatically storing the information into a TimescaleDB database. It achieves automated data acquisition and persistent storage. The highlights include an efficient scheduled triggering mechanism and streamlined data processing workflow, ensuring data is captured in real-time, accurately, and stored in a structured format for easy subsequent analysis and querying.
Core Problems Addressed
It solves the inefficiencies and error-prone nature of manually acquiring and recording ISS location information by implementing an automated process for continuous data retrieval and storage, significantly enhancing the timeliness and reliability of data collection.
Application Scenarios
- Real-time monitoring of space station trajectories by aerospace research institutions
- Educational demonstrations using ISS location data in academic settings
- Historical trajectory data analysis by data analysts
- Development of applications or services based on ISS location data by developers
Main Process Steps
- Scheduled Trigger (Cron): Automatically initiates the workflow every minute to ensure real-time data updates.
- API Request (HTTP Request): Sends requests to the open API at “wheretheiss.at” to fetch the current ISS location data at the given timestamp.
- Data Extraction and Formatting (Set): Extracts latitude, longitude, and timestamp from the API response and formats it into structured data.
- Data Storage (TimescaleDB): Writes the formatted data into a predefined TimescaleDB table, supporting efficient storage and querying of time-series data.
Involved Systems or Services
- wheretheiss.at API: Provides an open interface for real-time ISS trajectory data
- TimescaleDB: A PostgreSQL-based time-series database optimized for storing time-series data
- n8n Automation Platform: Facilitates automated orchestration of data collection, processing, and storage workflows
Target Users and Value
- Aerospace researchers and engineers for convenient tracking and analysis of ISS trajectory data
- Data scientists and analysts seeking quick access to reliable time-series data sources
- Educators providing authentic data to support teaching and demonstrations
- Automation developers using this as a reference case for API data collection and time-series database storage techniques
By leveraging automation, this workflow delivers a stable, efficient, and maintainable solution for ISS trajectory data acquisition, effectively reducing manual operation costs and enhancing the value of data applications.
Extract Information from an Image of a Receipt
This workflow can automatically extract key information from receipt images, such as the merchant, amount, and date. It retrieves receipt images through HTTP requests and calls an intelligent document recognition API to achieve accurate recognition and parsing, significantly improving the efficiency and accuracy of manual data entry. It is suitable for scenarios such as financial reimbursement, expense management, and digital archiving of receipts, helping users quickly obtain structured information, reduce errors, and enhance data management and analysis capabilities.
ETL Pipeline
This workflow implements an automated ETL data pipeline that regularly scrapes tweets on specific topics from Twitter, performs sentiment analysis, and stores the data in MongoDB and Postgres databases. The analysis results are filtered and pushed to a Slack channel, allowing the team to receive important information in real time. This process effectively avoids the tedious task of manually monitoring social media, improves data processing efficiency, and supports quick responses to market dynamics and brand reputation management.
Daily Product Hunt Featured Products Scraping and Updating
This workflow automatically retrieves the latest product information published on the Product Hunt platform every day, including the name, tagline, description, and official website link. It intelligently handles redirects and unnecessary parameters in the official website links to ensure data accuracy and conciseness.
