Satellite Safari is your tour guide to the universe of satellites that humanity has launched into orbit around our home planet.
The Unofficial Apple Weblog (TUAW) writes: "My tests of the app were positive. No crashes, no surprises... A very cool app." Here's the full review:
You can use Satellite Safari to learn more about the International Space Station and many hundreds of other satellites already in orbit. Satellite Safari will tell you where to find them in the sky, when they'll pass overhead, and where they are orbiting over Earth right now.
Satellite Safari can show you the spacecraft that will pass over your location at any given time. You can even get a "bird's eye view" from a satellite itself, and see the Earth from orbit exactly as the satellite sees it!
Satellite Safari updates its satellite orbit data from celestrak.com automatically every day. All satellites include facts and figures computed for your precise GPS location, and updated every second. Many satellites also include descriptions that give you the mission's history, purpose, and more.
Satellite Safari's simple user interface and super high accuracy make it an invaluable tool for exploring the spacecraft in orbit around our home planet. Please feel free to contact us at www.southernstars.com if you have further questions. We hope you enjoy using Satellite Safari!
Intuitive and powerful satellite tracker to view International Space Station(ISS), Hubble Space Telescope(HST),Tiangong1(天宮一号) and others with your naked eye using Augmented Reality technology.
This simulates a way of satellite on top of reality through the camera and map.
Not only satellites,planets,fixed stars,galaxies,black hole,spacecrafts(Voyager1, Voyager2, New Horizons etc.),tweets and even world cities are shown as if earth was transparent.
Displaying geostationary orbits will also be very helpful when you adjust a parabolic dish antenna.
It connects Twitter too. So you can share excitements of finding satellites and weather conditions with others all over the world.

You will not find ads in our games, as we think ads only take away attention from what's going on inside the game and they do not provide much value to the player.
The game has a few levels. First two are free and the rest you can unlock by an in-app purchase.
* DISTANCE FROM SUN - Drag the planet above to the correct place between the planets below (according to the distance from Sun)
* TIMELINE OF SOLAR SYSTEM EXPLORATION - Place the event in the correct chronological spot on the timeline of Solar system exploration
* FAMOUS ASTRONOMERS - Do you know who was first – Galileo or Copernicus?
* PLANETS SIZE - Place the planet according to its size – smallest on the left
* SEND SPACECRAFT TO THE PLANET - Pick the right planet the spacecraft was sent to
* PLANET’S NATURAL SATELLITES - Do you know which moon belogs to which planet?

Before long, your phone chirps in your pocket to let you know! Pulling out your phone, you see a 3D view of the sun a digital reconstruction of images freshly downloaded from NASA's "STEREO" satellites, orbiting millions of miles away.
You rotate the sun with your finger to view it from any angle. You pinch in and out to zoom in
for a closer look at the sun's ever-changing surface.
Now *this* is living in the 21st Century! :-)
"3D Sun" lets you carry a virtual window onto today's sun, right in your pocket. Open this app
anytime to see what's happening today on the sun's ever-changing surface. See when major solar flares erupt on the sun's surface. Track sunspots that reveal the churning activity inside the sun's fiery inferno.
News alerts provided by a Ph.D. trained astrophysicist inform you of important solar
events. Optional push notifications will alert you of the most important events even when "3D Sun" is not running.
Great for aurora watchers who want to be notified of when they should look up!
Along with the 3D view of the sun, this app is frequently updated with movies and image
galleries of solar events, such as massive explosions on the sun and the beautiful auroras,
or "northern lights," that those explosions can trigger.
Developed in collaboration with NASA scientists.
NASA's STEREO mission is a pair of satellites orbiting on nearly opposite sides of the sun.
Together, these two satellites provide an unprecedented wrap-around view of most of the
sun's surface each day. "3D Sun" provides the first-ever 3D display of STEREO's images, right on your Android phone.
Some satellites carry radio repeaters that can be used by amateur radio from the ground.
This application helps the amateur to know the real time position of these satellites.
It shows on the map the position of the satellite, semi circle representing the approximate coverage as well as the user's position.
You can switch from the menu the selected satellite.
From the menu visible passes shown a window with two buttons on the top.
Pressing the right (circular arrow) visible passes are calculated for the selected satellite within 24 hours.
Pressing the left (arrow circular dot in the center) visible passes are calculated for all satellites for the next 3 hours.
Clicking on one of the visible passes entered the 3D locator.
The locator uses accelerometer, the compass of the device and the calculated data to show the position of the satellite on sky from observer's position.
That is, when we moves the device to the sky shows a red triangle in the position of the satellite and a dotted line showing the pass.
The app calculates the orbits from the current time of the device and TLE data that www.celestrak.com obtained.
The internet is used to get the maps and update TLE data.
If you like the app you can make a donation to the developer from the menu extensions.
Option to manually include the TLE data in a file on the SDCard with satellites that the user wants is added.
For each satellite include 3 lines like these.
1 24792U 97020A 13350.44946552 .00000550 00000-0 18933-3 0 6234
2 24792 86.3985 133.2143 0002 005 108.3180 251.8234 14.34218916869917
From the preferences menu of the main screen mark the check
"TLE data from file in SD"
For now, this option is only available to donors users.
The first time you do not get frequency data automatically.
Frequency data from the window "visible passes"
In each satellite pass, if a letter F appears in blue,
When pressed frequency data for this satellite are deployed.
Data is obtained automatically the first time from:
If you want to update later will be done by checking
"Last updated Frequency data" in the preferences window.
If you want to learn something about the satellites you are seeing instead of just getting a name and a number (what is an SL-16 R/B anyway?) this is the app that does that. For each satellite listed there is a description and a photo (when available). And our dataset is maintained by pros so we only track the most interesting of the 100's of visible satellites.
As an educational tool for casual sky watchers, Satellite Flybys beats the others hands down. And if you are an avid satellite spotter, this app is a good way to introduce others to your hobby. Also, unlike some of the other satellite spotting apps, the flyby predictions are stored so they are available offline. That's important if you go out to a nice dark sky area to view flybys and don't happen to have cell coverage there.
