AndroideSimple

ISS?

AndroideSimple
The ISS (International Space Station), completing one orbit around the earth every 92 minutes, approximately.

This application places the ISS on the map in real time.

Calculate the orbit from the current time of device and TLE data, which obtained www.celestrak.com.

Green line is drawn 50 minutes before and after the current position of the ISS.

The user's position is marked with an android with the arm held high, surrounded by a semi-transparent red circle.

The red circle indicates approximately the area where the ISS would be visible by the user. That is, if the ISS is inside the circle, in theory, you could watch it at the sky. Remember, NEVER LOOK DIRECTLY AT THE SUN!

Internet access is used to obtain maps and update once a day TLE data. More zoom means more data traffic.

From the preferences menu you can enable/disable automatic tracking on the map.

The local time Can also be superimposed on the map.

Visible Passes.

Although you can get to see the ISS for the day is much easier to see at night, because in the night sky is the second brightest object after the Moon and before of Venus.

But to be visible at night must be some circumstances:

-The ISS must be illuminated by the sun, ie outside the cone of shadow of the Earth.

-The sun must be at least 10 degrees below the horizon or, in other words, must have had at least 40 minutes before or must miss more than 40 minutes to come out.

-In its pass, the ISS must rise more than 5 degrees above the horizon. Less than 5 degrees is not visible by the distortion generated by the atmosphere.

From the main application window, pressing the menu key you can select "Visible Pass".

From this screen we have the date, time and position of the observer and a refresh button (circular arrow).
Pressing the button proceed to calculate the visible pass for the next 2 days (changeable in preferences screen).

The result is a list of steps visible. Each step consists of:

-Day and month.

-Initial instant. Time, altitude in degrees, azimuth in degrees (cardinal point equivalent)
-Instant of Maximum altitude. Time, altitude in degrees, azimuth in degrees (cardinal point equivalent)
-Final instant. Time, altitude in degrees, azimuth in degrees (cardinal point equivalent)

Alarms: You can on/off pressing alarm button (top-left icon).

3D Locator.

The locator uses accelerometer, the compass of the device and the calculated data to show the position of the ISS 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 ISS and a green dotted line showing the ​visible pass.


It also includes a positioning aid, based vibration:

- Hold the device pointing to the horizon, turn on your feet so as to vary only the azimuth (N, NE, E, SE, S, SW, W, NW). When the azimuth differs from the ISS in less than 10 ° there is a vibration.

- Now vary the altitude, vibration intensifies as it approaches the ISS and will be greatest when the red triangle is displayed.

- You can activate / deactivate the vibration by touching the screen.

Notes:

Altitude: The angle of a celestial object measured upward from the horizon of the observer. An object on the horizon has altitude 0 ° while one directly overhead the observer is 90 °.

Azimuth: The direction of celestial object measured along the direction of clockwise from the northern horizon of the observer. An object in the north has azimuth 0 °, east 90 °, south 180 ° and 270 ° west

Ping Pong Matrix

AndroideSimple
To play Ping Pong Matrix need a friend.
Every android device is a field.
With one finger you control your bat.
The ball moves from one device to another by bluetooth.

To start playing the app has to be running on both devices.
You have to pair the devices via Bluetooth.
In one press menu and select "Discoverable".
At the other press menu and select "Connect".
Choose the device to your friend. Sometimes you need to specify a password ("1234" for example) on both devices.

Once paired again select "Connect" and start the game.

May the best win.

Tiangong 1?

AndroideSimple
Tiangong 1 is a Chinese space station under construction that is in orbit since September 29, 2011.

This application places Tiangong 1 on the map in real time, and other 146 satellites, including the ISS. (I recommend install before "ISS?" , is more easy).

Calculate the orbit from the current time of device and TLE data, which obtained www.celestrak.com.

Red line is drawn 50 minutes before and after the current position of the satellite.

The user's position is marked with an android with the arm held high, surrounded by a semi-transparent red circle.

The red circle shows approximately the area in which the satellite would be visible by the user.

Internet access is used to obtain maps and update once a day TLE data. More zoom means more data traffic.

From the main application window, pressing the menu key, you can select other satellites.

Visible pass:

At night you can see many satellites, some are very bright as the ISS and others require a more darker sky.

From the main application window, pressing the menu key, you can select "Visible Pass".

From this screen we have the date, time, position of the observer and two buttons.

Pressing the left button (arrow circular with dot in the center) are calculated the visible passes for all satellites for tonight, sorted by time of onset.

Pressing the right button (circular arrow) the visible passes are calculated for the next two days for satellite selected on the main screen.

Clicking on one of the visible passes entered the 3D locator.

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 red dotted line showing the ​visible pass.

Iridium

AndroideSimple
The Iridium communication satellites have a peculiar shape with three polished door-sized antennas, 120° apart and at 40° angles with the main bus.

Occasionally, an antenna reflects sunlight directly down at Earth, creating a predictable and quickly moving illuminated spot on the surface below of about 10 km diameter. To an observer this looks like a bright flash, or flare in the sky, with a duration of a few seconds.

This app displays in real-time where is each Iridium satellite, predicts when these flares will occur from the observer's position and allows from the 3D locator, locate the exact point in the night sky.

Gets the data needed from android device (accelerometer, compass, location) and from the following urls:
www.celestrak.com and www.heavens-above.com

Divide

AndroideSimple
Divide is a simple game.

Children will learn simple divisions.

OSCAR

AndroideSimple
OSCAR: Orbiting Satellite Carrying Amateur Radio.

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.

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.

v1.2

Option to manually include the TLE data in a file on the SDCard with satellites that the user wants is added.

/sdcard/com.androidesimple.oscar/TLE.txt

For each satellite include 3 lines like these.
IRIDIUM 8
1 24792U 97020A 13350.44946552 .00000550 00000-0 18933-3 0 6234

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:
http://www.ne.jp/asahi/hamradio/je9pel/satslist.htm

If you want to update later will be done by checking
"Last updated Frequency data" in the preferences window.
