Where the Rassvet constellation actually is, right now
Rassvet is the low-orbit broadband constellation being built by Bureau 1440. This page reads the public orbital catalogue every time you load it, works out where each Rassvet satellite is and how high it is flying, and shows the result next to the figures the operator publishes about the service. Every measurement below comes from tracking data, and the method is written out at the bottom.
Live positions and coverage
Each dot is one satellite, moving in real time. The shaded circles show the ground a satellite at the fleet's main altitude currently has in view above 25°. A constellation provides continuous service once those circles overlap everywhere it covers, so the size of the gaps is a direct measure of how far along the build-out is.

The short answer
What the operator states, and what the catalogue shows
These are the figures Bureau 1440 publishes about the service on its own site, each placed next to the corresponding measurement from today's catalogue. Where orbital elements cannot speak to a claim one way or the other, that is said rather than left out. No other party's account of the programme is used or quoted anywhere on this page.

Progress against the federal project target
The constellation is being built under the federal project «Инфраструктура доступа к информационно-телекоммуникационной сети „Интернет“», part of the national project «Экономика данных и цифровая трансформация государства». Its indicator is an increase in the number of functioning spacecraft in the low-orbit broadband constellation, from zero to 292 by the end of 2030.
Whether a spacecraft is functioning is not something a catalogue of orbits can establish. So the two bars below show the two things it can count: how many objects are in the catalogue at all, and how many of those are at the fleet's main altitude. Neither is the quantity the indicator asks for, and the real figure is not necessarily either of them.
Altitude of every satellite
Satellites are released low and raise themselves over a period of weeks, so a batch spreads out in altitude while it climbs. The shaded band is the altitude where most of the fleet currently sits, found by clustering the satellites' own altitudes rather than taken from any announcement. How long each satellite has been in orbit is in the table below.
Orbital planes
A constellation covers the globe by spreading satellites across planes that cross the equator at different longitudes. Each batch so far has gone into one plane.

Launch history
How these numbers are produced
- Where the orbits come from
- Celestrak's general perturbations catalogue, filtered to objects named RASSVET. This is the same public data every tracking site uses. The page shows how old the newest and oldest element sets are so you can judge how current the answer is.
- Altitude
- Derived from the mean motion through Kepler's third law, then reduced by the Earth's equatorial radius. Perigee and apogee use the catalogued eccentricity. These are mean elements, so values are accurate to roughly a kilometre, which is far below the distinctions being drawn here.
- The federal project target
- Taken from the project's own indicator, cited by name in the list below and not from anyone's reporting of it. The indicator counts functioning spacecraft; this page counts catalogue entries and altitudes, which are not the same thing, and it says so where the figures appear rather than letting them pass as equivalent.
- The main altitude
- Not taken from any published figure. Altitudes are binned in 25 km steps and the most populated bin is treated as the fleet's main altitude, so if the satellites move the page follows them. A satellite is counted as being at that altitude within ±20 km of it. This is a description of where the fleet currently is, not a statement about where it is meant to be.
- Which way an orbit is moving
- The catalogue fits a drag term to each object, and atmospheric drag can only ever shrink an orbit. A fit showing an orbit that is growing therefore means energy is being added to it. The page reports only that: whether an orbit is currently growing or not. It does not report why, because the catalogue cannot show that - a satellite between manoeuvres and one that is not manoeuvring look the same in a single element set. Time since launch is given alongside so the reader can weigh a low altitude themselves.
- How many objects a launch put up
- Read from the international designators rather than from any published launch report. Every object of a launch is given a designator ending in a letter, issued in sequence, so the highest letter present shows how many were catalogued and any letter skipped below it belongs to an object that was catalogued at some point and is not in the feed now. That is reported as exactly what it is - a designator with no current entry - and nothing is inferred about why.
- Footprint and coverage
- A satellite's footprint is the ground within which it sits at least 25° above the horizon, a typical minimum for a flat-panel user terminal. The coverage figure is the share of the Earth's surface inside at least one working satellite's footprint at that instant, computed by sampling an equal-area grid.
- Live positions
- Propagated in your browser with SGP4 from the same elements, updated every second. Nothing about your location leaves your device.
Everything this page draws on
Two sources, and no others. The measurements come from the catalogue; the published figures come from the operator.
This is an independent page, not affiliated with or endorsed by Bureau 1440. It reports measurements taken from a public orbital catalogue alongside figures the operator publishes about itself, and it draws no conclusions about the causes behind them or about the programme's prospects. Orbital elements are a snapshot: they show where an object was at one moment, not whether it is working, under control, or doing what its operator intends. Where a published figure and today's measurement differ, both are shown side by side. Corrections are welcome.
