Satellite Safari is your tour guide to the universe of satellites that humanity has launched into orbit around our home planet. And later this year, it will become your personal gateway to a real satellite in orbit that you can take pictures and send broadcasts from!
Satellite Safari is the official app of the SkyCube mission. The SkyCube satellite launched to the International Space Station on January 9th, 2014. It deployed from the ISS on Febrary 28th, 2014. And soon, you'll be able to request your own images of the Earth, and broadcast your own radio messages from orbit as "tweets from space", using this Satellite Safari app on your iPhone or iPad. For more information on the SkyCube project, go to www.skycube.org.
The Unofficial Apple Weblog (TUAW) writes: "My tests of the app were positive. No crashes, no surprises... A very cool app, which will only become more useful this fall when the SkyCube features ramp up." 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!

Through this application you will come to better understand the benefits that the EU's Galileo and EGNOS programmes bring to your daily life, both private and professional.
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?

The full version of Exoplanet Explorer 2 introduces a feature that will automatically download the latest planetary discoveries, keeping you up to date. For the first time it also includes models of some of the binary star systems that are known to have planets, giving you a much better idea of the variety of different worlds in our Galaxy.
The data is sourced from The Planetary Habitability Laboratory, SIMBAD, and scientific papers, and if it's not available from one of these sources, then wherever possible it will be calculated or estimated, giving you access to one of the most complete exoplanet databases.
In addition to an intuitive interface which allows touch driven navigation through our Galaxy, Exoplanet Explorer also offers a comprehensive search tool which will let you find the planets and systems that you are interested in. This includes the ability to both search and sort by planet name, the number of planets in a system or even then number of stars in a system, to name just a few.
Statistics are provided to summarise the information in the database and give you a global perspective.
Planets have been divided up into 6 classes, and further subdivides into 3 temperature classes. This information has then been used to create models which are then assembled into working solar systems to give you an idea of what they might look like if we could travel there today.
Planet are divided into the following mass classes:
* Mercurian - rocky worlds that have the approximate mass of Mercury
* Sub-terran - rocky planets with a mass similar to Mars
* Terran - rocky worlds with similar mass to Earth
* Super-terran - rocky worlds with a higher mass than Earth
* Neptunian - gas giants similar to Neptune
* Jovian - gas giants as massive or more massive than Jupiter
The planets are further divided into the following temperature classes:
* Hot - planets that are too hot to support liquid water
* Warm - planets in the star's habitable zone where liquid water could exist
* Cold - planets beyond the habitable zone where water would only exist as ice
* Please report problems at apps.burlock.org or email at firstname.lastname@example.org. I can't help you here because Google won't let developers contact users who make comments.
* This app supports ICS, but custom ROMs are not supported. If you install a non-standard ROM and have a problem, then contact the ROM developer and report the bug so they can fix it.

WiFi Heat is simple to use--you can create an informative map in minutes. It will create a detailed heatmap that can be used for adjusting your wireless access point settings or location for maximum speed, signal quality and best coverage. You can either use your own floor plan, or simply use Google Maps satellite view. Once you have a map imported into WiFi Heat, you simply walk around the area the map represents and mark your position.
* WiFi heat will display the signal strength of every wireless network in your survey area.
* Supports multiple building levels and will display 2D or 3D signal strength maps of an area.
* WiFi Heat helps you select which channel is the quietest for minimum interference from neighbors.
* WiFi Heat uses a unique algorithm which accurately estimates signal strength in unknown areas.
* Designed for both phones and tablets, in portrait and landscape orientations.
* Supports metric and imperial systems.
* Visualizations are distinguishable for people who are color blind.
* Professionally made with no tolerance for bugs.
If you see anything that you like, would like, or don't like in WiFi Heat, please let us know! We are happy to receive feedback of any kind. Leave us feedback at http://wifiheat.com/
Please note that parabolic antennas have not been tested, so the generated visualisations might not be as accurate as an omnidirectional antenna.
OCEARCH facilitates unprecedented research by supporting leading researchers and institutions seeking to attain groundbreaking data on the biology and health of sharks, in conjunction with basic research on shark life history and migration.
In addition to the supplied stars, the app allows you to import more data from external sources, with built in support for the format used by two of of the most popular collections, HYG and XHIP. If this isn't enough, you can also create your own data file, including any fields you'd like to see, and import it into Galaxy Explorer using the generic importer.
Although the built in database of 15,000 stars should run on any device, if you choose to download a large dataset containing around 100,000 or more stars, then you'll need a good graphics chip and at least 1MB of RAM.

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.
