Point this at your address and it answers that question literally. Project Over Head
Live plots every aircraft currently in the sky above you on a single overhead view —
the same view you'd get lying on your back and looking straight up. Positions refresh
roughly every 15 seconds, and clicking any aircraft shows its callsign, altitude,
speed and heading.
There's nothing to install and no account to create. Type an address, a postcode, or a
raw latitude, longitude pair, or tap Use my current location
and the map centres on you immediately.
The ISS, satellites, stars and planets — all in the same sky
Aircraft are only the lowest layer. The same overhead view also renders the
International Space Station, updated about every 10 seconds, alongside satellites
ranging from recognisable craft like Hubble and Tiangong up through the full Starlink,
OneWeb and Kuiper constellations if you want them.
Behind all of that sits the real sky: named stars, the planets, the Sun and the Moon,
each computed from your exact coordinates and the current time rather than pulled from
a generic star chart. Deep-sky objects — the Andromeda Galaxy, the Orion Nebula, the
Pleiades — are marked at their true positions too. Day and night modes shift the
palette so the view stays readable whether it's noon or 3 a.m.
Put the real sky on your ceiling
The view was built for a projector. Switch Orientation to
Projector, point the projector at your ceiling, and rotate the image so
the N marker faces geographic north. The map mirrors itself so east
falls on your left — which is what east actually does when you lie down and look up.
The result is a 1:1 replica of the sky above your roof, planes and all.
Unlike the Raspberry Pi builds of this idea, there's no hardware to buy: no
software-defined radio, no antenna, no single-board computer. It runs in a browser tab
on whatever you already own, which also means it works at any address, not just the one
your antenna can hear.
Where the data comes from
Live aircraft positions come from the
OpenSky Network
and airplanes.live,
both community-run ADS-B networks, with callsign and route lookups from
adsbdb.
ISS telemetry comes from
wheretheiss.at.
Satellite orbits are propagated locally in your browser with SGP4 from
CelesTrak
orbital elements, and the positions of stars, planets, the Sun and the Moon are
calculated on your device from your coordinates — none of that needs a round trip to a
server. Address search is geocoded by
Nominatim
using open data from
OpenStreetMap contributors.
Coverage depends on those volunteer receiver networks, so quiet or remote areas will
show fewer aircraft than a busy approach corridor. Military and other non-broadcasting
traffic generally won't appear at all.
Desktop: map view (N up, E right). Projector: mirrored for a ceiling —
orient N to true north and East falls on your left, matching the real
sky when you look up.
Satellites
Computed live with SGP4 from CelesTrak orbital data. Heavier tiers show
far more objects and use more processing — “Recognizable” is the smoothest
and is the default for the best experience on any device.
Deep-sky objects
Galaxies, nebulae & clusters — Andromeda, the Orion Nebula, the
Pleiades and more, visible to the eye or a backyard telescope.
Constellations
Joins the catalogue stars into the classic figures and names them.
Turn it off for a clean sky.
Meteor showers
Marks the radiant of any shower active tonight — the point its meteors
appear to come from. Nothing is drawn when none is running.
Aurora
Glows on the poleward horizon when NOAA's planetary K index puts the
auroral oval within reach of your latitude.
About Project Overhead Live
Project Overhead Live renders a real-time map of everything
above you — commercial flights, the International Space Station, named
stars, planets, and the Moon — all projected onto a single overhead view
anchored to your exact location.
🎥 Best on a projector. Switch Orientation to
Projector, point it at your ceiling, and turn the image
so the N label faces geographic north — you'll see a true
1:1 replica of the sky above you (East falls on your left, just like the
real sky when you look up). Enable night mode for full star visibility.
