How many satellites are in orbit right now?

RocketMapper tracks thousands of active satellites across 14 constellations including Starlink, ISS, GPS, OneWeb, Galileo, BeiDou, and more. The exact count updates in real time as new satellites are launched and old ones deorbit.

How does the RocketMapper satellite tracker work?

RocketMapper uses Two-Line Element (TLE) data from CelesTrak and applies SGP4 orbital propagation to calculate precise real-time satellite positions. The results are displayed on an interactive 3D globe that updates every second.

Can I track Starlink satellites in real time?

Yes, RocketMapper tracks every active Starlink satellite in real time. Open the satellite tracker, select Starlink from the sidebar, and see all satellites plotted on the 3D globe with live altitude, velocity, and position data.

Where is the International Space Station right now?

You can see the real-time position of the ISS on RocketMapper's satellite tracker. Click the ISS dot on the 3D globe to see live altitude, speed, latitude, longitude, and upcoming crew and cargo missions.

What satellite constellations does RocketMapper track?

RocketMapper tracks 17 satellite systems: International Space Station, AST SpaceMobile, Planet Labs, EchoStar, Spire Global, SpaceX Starlink, OneWeb, Iridium NEXT, GPS (NAVSTAR), Galileo, BeiDou, GOES, METEOR, NOAA POES, ICEYE, Capella Space, Umbra. Each constellation has its own detailed page with satellite count, orbital information, and deployment launch history.

Is the satellite tracker free to use?

Yes, RocketMapper's 3D satellite tracker is completely free to use. No account or sign-up required. Simply visit rocketmapper.com/satellites to start tracking satellites in real time.

How many Umbra satellites are in orbit?

There are currently 5 Umbra imaging satellites being tracked in Low Earth Orbit (LEO). RocketMapper updates this count in real time using TLE data from CelesTrak.

What orbit do Umbra satellites use?

Umbra operates in Low Earth Orbit (LEO) at approximately 200–2,000 km altitude. The constellation is operated by Umbra Lab.

How can I track Umbra satellites in real time?

You can track Umbra satellites live on RocketMapper's interactive 3D satellite tracker at rocketmapper.com/satellites. The tracker uses SGP4 orbital propagation with TLE data updated regularly from CelesTrak to show precise real-time positions, altitude, and velocity.

Umbra is operated by Umbra Lab.

Can I see Umbra satellites from the ground?

Umbra satellites in Low Earth Orbit may be visible as moving points of light in the night sky shortly after sunset or before sunrise, depending on conditions and satellite size.

What type of imagery does Umbra provide?

Umbra uses Synthetic Aperture Radar (SAR) to capture high-resolution imagery day or night and through cloud cover. This makes it particularly valuable for defence, maritime monitoring, disaster response, and environmental analysis.
