ISS Current Location Badge

Tracking since Apr 14, 2026.

Changelog

• May 27, 2026
  description

  ISS Current Location Badge lets you track the International Space Station directly from the Chrome toolbar.
  
  Features:
  - Live toolbar badge showing ISS status
  - Popup with the latest ISS latitude and longitude
  - Compact map view of the current ISS position
  - Optional use of your current location to estimate the next overhead pass
  - Local pass prediction using TLE orbital data
  - Diagnostic logs for visible troubleshooting
  - Multi-language popup UI
  
  How it works:
  - The extension refreshes ISS position data in the background on a fixed interval
  - It fetches orbital TLE data to estimate future overhead passes
  - If you choose to allow location access, the extension uses your location only to calculate pass timing for your area
  - Location access is requested only after explicit user action inside the popup
  
  Data sources:
  - Open Notify for current ISS position
  - CelesTrak for orbital TLE data
  - OpenStreetMap tiles for map display
  
  Who it is for:
  - Space enthusiasts
  - Students and teachers
  - Users who want a lightweight ISS tracker in Chrome
  
  Notes:
  - Overhead pass prediction depends on location permission and availability of TLE data
  - If live data cannot be fetched, the extension falls back to the last cached state and shows a visible error status
  - Some optional feedback features may send user-provided responses and related technical metadata only when the user explicitly chooses to submit feedback

  ISS Current Location Badge provides a lightweight and privacy-conscious way to monitor the current position of the ISS in real time. The extension displays live ISS status information in the toolbar badge and offers quick access to orbital data, map visualization, and local pass predictions.
