Orbitrack is your desktop and pocket guide to the thousands of spacecraft orbiting our home planet.

For MacOS, iOS, and Android!

Double the Fun

Orbitrack for MacOS, iOS and Android is an advanced satellite tracking app.  It features a database with thousands of spacecraft, plus augmented-reality and virtual-reality modes with voice commands.

Orbitrack includes every active orbiting satellite, plus space debris and rocket boosters large enough to be visible, and now includes classified military satellites.

Rich new graphics, written in the latest OpenGL and Metal APIs, show atmospheric effects, city lights on Earth’s night side, and highly-detailed 3D satellite models.

Orbitrack predicts and displays Starlink satellite passes, and lists radio frequency data for amateur radio satellites.

Descriptions for hundreds of spacecraft have been updated.  Every satellite now has a description from n2yo.com.

Orbitrack supports the latest Apple hardware and software, including iPhone X/11/12, iPad Pro, and iOS 14.  The Mac version runs on MacOS 10.15 (Catalina) and later, with fully native support for both Intel- and Apple Silicon-based Macs.

And for phones, Orbitrack runs in stereo, with a new voice-controlled Virtual Reality mode compatible with any smartphone VR viewer!

Track thousands of satellites – in orbit and overhead!

Orbitrack will tell you when spacecraft pass overhead, show you where to find them in the sky, and let you track them across the planet.  A new Augmented Reality (AR) Sky view blends video from your phone camera, GPS, and motion sensors to display satellites as they cross your sky!

Get the “Bird’s” eye view

You can show the view from any satellite, and see the Earth from orbit just as the “bird” sees it!  Orbitrack includes detailed 3D models for dozens of satellites – see them up close from any angle!  If you have a smartphone VR viewer, you can see them in stereo.  It’s the most realistic spaceflight experience you can get without leaving the planet!

Stay on top of the space race

Fascinating mission descriptions will teach you about the International Space Station, and hundreds of other satellites in orbit.  Orbitrack updates its satellite data from n2yo.com and celestrak.com every day.  When new spacecraft are launched, maneuver into new orbits, or fall back into the atmosphere, Orbitrack shows you what’s happening up there, right now.

Power and Simplicity

Orbitrack isn’t just powerful – it’s incredibly easy to use!  You don’t need an aerospace degree to become an expert satellite tracker.  Orbitrack puts advanced capabilities at your fingertips, with the same intuitive touch interface you use every day.  And if that’s not enough, it includes detailed, built-in Help – and expert, responsive technical support.

Available now for MacOS, iOS, and Android!

Orbitrack is available today on the iTunes Store and Google Play. The iOS version requires iPhone 6 or iPad 2 running iOS 10 or later. The MacOS version requires MacOS 10.15 (Catalina) or later. The Android version requires Android 6 or later, and runs on Android devlces with both ARM and x86 processors.

Two features present in Orbitrack for iOS are not yet available in the Android version: camera-blended Augmented Reality, and voice-controlled Virtual Reality.  These will be added to the Android version in forthcoming updates.  Otherwise, the iOS and Android versions are feature-identical.

Critical Acclaim and User Praise for Orbitrack and Satellite Safari

"Satellite-focused mobile apps are the best tools for tracking the myriad satellites that are visible with unaided eyes ... One of them, a new app called Orbitrack, now offers an immersive virtual-reality view of the sky and voice commands to assist in your hunt!"

Chris Vaughan, space.com [Full Review]

"Orbitrack is a wonderful app for satellite watchers. The sheer numbers of satellites available will keep dedicated satellite watchers busy for years. Casual sky watchers always want to know what satellites they can see in their night sky and Orbitrack will keep them looking up with its ease of use, including its Augmented Reality mode. The extensive satellite descriptions and Virtual Reality mode to view satellites in 3D will educate and entertain its users. Orbitrack is highly recommended for all levels of satellite watchers."

Mike Weasner, Cassiopeia Observatory [Full Review]

"I've been playing with a new app called Orbitrack, which lets you see what satellites are visible to you in the sky, their orbits, and much more. It's pretty cool! From the same folks who made SkySafari, my fave planetarium app."

Phil Plait - The Bad Astronomer [Link]

"Southern Stars released what is likely the best iOS satellite tracker available – Orbitrack, a successor to their Satellite Safari. It tracks thousands of orbiting satellites, including military satellites, and has detailed 3D models, facts, mission descriptions, and when satellites will be visible for one’s location. Southern Stars has been innovating astronomy software for many many years. I found it intriguing that one can see the perspective from the satellite’s view, complete with a 3D model, beyond seeing all of them orbiting together."

Brian Wiser - Call A.P.P.L.E [Link]

"I regard [Satellite Safari] as authoritative ... Amateur astronomers, wanting to get a photo of the ISS, could use it to plan the pass. Government and military people could use it for all kinds of planning operations. And teachers, students and even casual users just wanting to learn more about particular satellites could learn a lot ... It would be hard to ask for anything more."

John Martellaro, The Mac Observer [Link]

"My tests of the app were positive. No crashes, no surprises... Satellite Safari not only does good math, but displays its graphics in a compelling way... A very cool app, which will only become more useful this fall when the SkyCube features ramp up."

Mel Martin, The Unofficial Apple Weblog [Link]

"At 7:00 last night, I used Satellite Safari to 'play a movie' of the satellites that would be visible during the upcoming couple hours. It showed a favorably placed crossing of two naked-eye satellites. Here is an animated GIF of six 5-second exposures of intersecting pieces of space junk.The brighter one is an Atlas Centaur 2 launch vehicle that went into orbit in 1963. The fainter object is a Soviet Soyuz rocket body that launched one of their many Cosmos satellites in 1970. Close approach was over 40 miles, so no spectacular impact this time. It would have taken significant effort to predict this event without the using Satellite Safari. The app continues to amaze me."

Tom Polakis

"Well, they did it again. There are a lot of great and helpful astro apps out there but what keeps coming from Southern Stars are apps of another dimension. This app has in-depth research; it is amazingly user friendly; it raises the developer's high bar even higher; and it is awesomely gorgeous on the iPad. How many more high level apps can these amazing people make for us? They just keep surprising and delighting us."
