Loading orbit data...
Overhead turns a real satellite, passing over you right now, into a coin with a proof of the moment stamped inside it. Here is exactly what happens, and what the numbers mean.
Share your location or pick a city. Your browser downloads public orbit data from CelesTrak and runs the same orbit math space agencies use (SGP4) to place thousands of satellites, Starlink included, in real time. Your location never leaves your device.
Live positions, updated every secondA satellite counts as overhead when it is more than 10° above your horizon. Each one stays up for only a few minutes, so a ring counts down how long you have to press Launch before it sets. Rarer orbits, like the ISS and Hubble, earn a higher rarity.
The countdown is the gamePress Launch and Overhead freezes seven facts: the satellite's name, NORAD ID, latitude, longitude, altitude, speed and the exact UTC time. They are joined into one line and run through SHA-256 in your browser. The first eight characters become the coin's orbit hash, like ORB-7F3A9C21. See it happen below.
The name, ticker and artwork are filled in for you, for example $SAT25544, or write your own. The art is the real Earth as it looked at that moment, with the satellite's path drawn over it. The orbit hash and the line that produced it go in the description. You approve one transaction in your own wallet and the coin is created on pump.fun. Overhead never holds your funds or keys.
Your coin gets a card sized for X, with the Earth, the ground track, the telemetry and the orbit hash. Set a re-pass alert and post again when the satellite comes back over you.
Save the card, attach it to your post
This is a real calculation, run in your browser, on an example reading of the ISS. Your launch does exactly the same with your satellite.
Change any digit, even the altitude by 0.1 km, and the hash comes out completely different. A stamp cannot be edited after the fact.
The exact line is printed in the coin's description on pump.fun. Paste it into any SHA-256 tool and the first 8 characters, in capitals, should match the stamp.
It fingerprints the captured data. It does not prove where you were standing. Anyone can compare the satellite's position against public orbit records for that time.
Every coin made on Overhead can be checked by anyone, in their own browser, with public data. Open any coin from the Launched coins tab and its page runs these checks live.
When a coin page opens, your browser reads the coin from Solana, finds the orbit line in its metadata, hashes it again with SHA-256 and compares it to the stamp. It then runs the satellite's public orbit data (CelesTrak) to that exact second and compares the position, and it compares the captured time with the block time of the transaction that created the coin.
A fake stamp, an edited number or a backdated time fails a check and the page says so.When you launch, Overhead checks the capture is fresh, then signs three things together: the orbit hash, the ticker and your wallet address. The public key is in the site's code, so the page verifies the signature itself. Copying a coin's metadata to launch from another wallet makes the signature fail.
Honest limit: it proves the coin came through this launchpad. It does not prove where you were standing.After your coin confirms on Solana, Overhead's server reads the transaction itself and only then lists the coin: it must have succeeded, been paid by your wallet and carry the exact metadata Overhead pinned. Listed coins become gold dots riding their satellites on the globe and feed the leaderboards.
Market caps come from DexScreener and can lag by a minute or two.Rarity is a collectible label based on where a satellite flies and how old it is. It says nothing about what a coin is worth.
Low Earth orbit, under 1,000 km. Weather, imaging and communications satellites that cross the sky most often.
Thousands of Starlink satellites fly in shells around 550 km. They are Common by orbit, there are always dozens above you, and they glide across the sky in lines. The fastest way to find something to launch from.
High low Earth orbit, 1,000 km and up. Fewer satellites fly here and they stay in view longer.
Medium Earth orbit, 2,000 km and up, like navigation satellites. A single pass can last hours.
Launched 25 or more years ago. Many are retired or silent, still circling long after their missions ended.
The International Space Station, Tiangong, the Hubble Space Telescope and Vanguard 1, the oldest satellite still in orbit.
On top of its tier, some satellites carry a Rare find badge. These are the ones people chase. The badge shows on the coin card, in the leaderboards and on the coin page.
The ISS and Tiangong. Humans live aboard, and every pass is a moment people look up.
Hubble, still taking pictures after more than 30 years in orbit.
NOAA, GOES, Meteor, Fengyun and other satellites that watch the weather for us.
Switched off for good, still circling in silence. Listed as non-operational in the public satellite catalog.
Spent rocket bodies and fragments from old collisions, tracked by name in the public catalog.
Paste that line into any SHA-256 tool, for example printf '%s' 'LINE' | shasum -a 256. The first 8 characters in capitals should equal the stamp. Then look up the satellite on CelesTrak and propagate it to that time to see where it was.
