About
Space coverage and tracking tools for people who care what's in orbit now.
Leo.space is an independent content and utility site focused on the operating layer of the space economy: launches, low earth orbit infrastructure, satellite operations, and the amateur radio community that talks to satellites with a handheld radio.
The site is built for readers who want concise, source-aware coverage — and for operators who need a practical tool open on their phone while they're pointing an antenna at the sky.
What's live
Features and tools
News
Source-aware editorial coverageArticles covering launch cadence, LEO infrastructure, satellite operations, and space policy — with clear source attribution on every piece. Original reporting, licensed summaries, and curated snapshots, always labeled.
Read the news stream →Tracking
ISS real-time positionLive ISS ground track, current latitude/longitude, altitude, and velocity pulled from a cached snapshot pipeline. TLE data refreshed from CelesTrak and Space-Track on a nightly schedule.
Open tracking →Satellites
LEO constellation catalogBrowse tracked constellations — Starlink, OneWeb, Iridium, GPS, Galileo, and more — with live TLE age indicators and per-satellite orbital data sourced from CelesTrak and Space-Track.
Browse satellites →Ham Radio
Amateur satellite operating guideA four-step guide for licensed operators working satellites from the ground. Equipment tiers by license class, a filterable satellite picker with band and modulation data, a Doppler shift calculator, and browser-side SGP4 pass predictions using your live TLE feed.

How we operate
Leo.space is not affiliated with any launch provider, constellation operator, or government agency. Coverage decisions are made editorially, not commercially.
Alongside articles, the site develops utility tools: real-time tracking, TLE feeds, pass prediction, and field-ready references for ham operators working LEO satellites.
Every article carries a source mode label — original reporting, licensed summary, or source snapshot. Readers always know what they're reading and where it came from.
Field Mode increases text size and contrast for outdoor use. HAM pages are designed to be bookmarked and read on a phone during a satellite pass.
Roadmap
What's coming
The current build is the editorial and tracking foundation. Next priorities:
- ›HAM pass audio cues — Field-mode audio alerts at AOS and LOS so operators don't have to watch a screen during a pass.
- ›Multi-satellite pass calendar — A combined schedule view showing all ham satellite passes for a location across a 24-hour window, exportable for offline use.
- ›Live TLE age indicators on ham pages — Show how fresh the TLE data is for each satellite directly on the frequencies and passes pages.
- ›APRS heard log — Display recently heard APRS packets relayed through the ISS digipeater.
- ›Expanded constellation catalog — Add more commercial and government constellations to the /sats browser with deeper per-satellite orbital metadata.
