Orbital Infrastructure

What "orbital infrastructure" actually means

Orbital infrastructure is the layer of permanent, working hardware humans keep in space: communications constellations, navigation satellites, crewed stations, and the gravitationally stable parking spots beyond Earth orbit where observatories and future depots loiter. This pillar of the live Asakasa Space Intelligence app turns that abstract idea into something you can rotate in your hand.

The centrepiece is Starlink. The app renders every active Starlink satellite — more than 10,000 of them — as a 3D shell wrapped around the globe. As of mid-2026 the active count sits in the rough range of 10,400 to 10,600: astronomer Jonathan McDowell logged about 10,413 in orbit and 10,397 working as of 1 June 2026 (HighSpeedInternet, citing McDowell), against a planned constellation of up to roughly 42,000. Around that hero layer, the map draws faint reference shells for the other systems that share the sky — so you see Starlink in context, not in isolation.

This is an independent fan and reference project. It is not affiliated with, endorsed by, or sponsored by SpaceX, Starlink, or any company or agency named here. Marks are used nominatively to refer to the systems themselves.

What you can see in the live map

Open the app and hit the Infrastructure dock button to enter the Constellation panel. From there you can search any satellite by name or NORAD ID, pull up a random satellite or the "satellite of the day," or tap a spot on the globe to find what is overhead. Toggle ORBITAL PATHS in the destination bar and the wider scaffolding of space appears:

• The orbital-regime rings — LEO, MEO and GEO drawn at their true altitudes, each labelled, so you can read the architecture of near-Earth space at a glance.
• Reference constellations — OneWeb's near-polar shell, the GPS navigation fleet, and Europe's Galileo, rendered faintly so Starlink stays the hero.
• Crewed stations — the International Space Station and China's Tiangong, each on its real circular orbit with a moving marker, both flying below most of the Starlink shell.
• Cislunar Lagrange markers — the gravitational parking spots where real observatories actually loiter (Sun–Earth L1 and L2) and where depots and habitats have been proposed (Earth–Moon L4 and L5).

Tap any satellite and a card shows its altitude, speed, orbit and ground track. The reading is simple: bright line = orbit (next ~95 min), faint line = ground track. Note that the 3D scene is deliberately stylized — distances like the Lagrange points (really ~1.5 million km out) and the Moon's orbit are compressed so everything fits one view; the geometry is real, the scale is not.

The orbital regimes: LEO, MEO and GEO

Almost everything humans operate lives in one of three altitude bands, and the trade-off between them is the whole story of orbital design. The table below uses standard reference figures, the same ones the app draws its rings at.

LEO is defined as roughly 160 to 2,000 km: below ~160 km atmospheric drag drags objects down, and the 2,000 km ceiling sits just under the Van Allen radiation belts (Low Earth orbit). Starlink's main shell sits near 550 km, where a satellite completes one orbit in about 95 minutes — roughly 15 orbits, and 15 sunrises, per day (NASA). Orbital speed there is about 7.6 km/s, so a single satellite crosses the continental United States in roughly ten minutes.

MEO is navigation country. GPS flies at about 20,200 km with a ~12-hour period (Medium Earth orbit), and Galileo at about 23,222 km with a ~14-hour period (Galileo). At 35,786 km a satellite's period exactly equals Earth's rotation, so it appears to hover over one spot — ideal for broadcast and weather (ESA — Types of orbits).

The altitude choice is the entire business thesis behind LEO broadband. Dropping from GEO (~35,786 km) to Starlink's ~550 km cuts round-trip latency from roughly 600 ms to about 25–60 ms (ESA) — close enough for video calls and gaming, which a geostationary link can't deliver.

Who else is up there: constellations, stations and Lagrange points

Starlink shares the sky with rivals and reference systems the app draws alongside it. OneWeb runs a near-polar LEO constellation at about 1,200 km and 87.9° inclination, with roughly 600-plus satellites across a dozen orbital planes (eoPortal — OneWeb). GPS and Galileo anchor the MEO band. Crucially, inclination caps coverage: a 53° shell never passes above 53° latitude, which is why Starlink layers in higher-inclination and near-polar (~97° sun-synchronous) shells to reach the poles (Orbital inclination). The app tints shells by inclination (43°, 53°, 70° and ~97°, per SpaceX's FCC Gen2 filings).

Two crewed outposts circle below the constellation. The ISS orbits at about 400–420 km and 51.64° inclination, lapping Earth roughly every 93 minutes (ISS). China's Tiangong flies near 389 km at 41.5°, with a ~92-minute period (Tiangong) — the app renders it on that true circular orbit.

Farther out sit the Lagrange points. Sun–Earth L1 (~1.5 million km sunward) parks solar observatories like SOHO and DSCOVR; Sun–Earth L2 (~1.5 million km anti-sunward) hosts deep-space telescopes including the James Webb Space Telescope and ESA's Gaia (NASA — JWST orbit). Earth–Moon L4 and L5 are the stable triangular points that lead and trail the Moon by exactly 60°, long proposed for propellant depots and habitats (Lagrange points). To see how that scaffolding extends into a permanent off-world presence, read the Space Colonization pillar.

How to read the data — and where it comes from

None of this is faked or animated for show. Every satellite dot is propagated in your browser using SGP4, the orbital model the US government published in 1980 and the world standardized on for two-line element sets (Simplified perturbations models). The orbits themselves come from CelesTrak's public GP (general perturbations) data and SATCAT catalog, derived from US Space Surveillance Network observations and free to everyone (CelesTrak GP data formats). Launch data comes from The Space Devs' Launch Library 2, a free nonprofit spaceflight API (Launch Library 2 FAQ).

Each satellite card also shows a COSPAR / International Designator such as 2024-007A, which encodes the launch year, the launch number that year, and the piece letter — the standard public way satellites are identified alongside their NORAD catalog number (International Designator). The US Space Surveillance Network tracks tens of thousands of orbital objects; the app's Learn panel cites roughly 34,000 catalogued (the precise figure varies by catalog).

This infrastructure is also self-cleaning. At end of mission, Starlink satellites deorbit to burn up in the atmosphere, and the FCC now requires LEO satellites to dispose of themselves within five years of mission end (FCC orbital debris) — the rule that keeps the shell from silting up.
