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.
If you like the app you can make a donation to the developer from the menu extensions.
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.

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.
v1.4
Fixed bug.
The first time you do not get frequency data automatically.
v1.3
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.

Could use a listing of all (fm at least) sats and their frequencies.

Really Sucks!!! Not enough Amateur Radio Satellites! No Uplink or Downlink Frequencies!!! AMSAT Droid Free is way better!!!

I would like to see a more vivid satellite footprint,or an adjustable colour one,otherwise its very nice.

Very useful software. But i couldnt able to add satellite which i want to see. TLE data is not updating. No way to add TLE data manually.

The only thing that I can imagine to make this app better would be to include the amateur radio frequencies, modes, offsets and PL tones for each satellite, perhaps accessible in a popup by single-tapping the satellite icon on the display? Please!

Great app, the live view of satellites in the sky is very useful. Minor problem in that when the live view is in use the haptic feedback in my phone vibrates intermittently, but I can live with that. Some ideas that would make this even better in future are brief details of satellite health; up/downlink frequencies (preferably with doppler shift calculation); the ability to see all (operational) satellites in view simultaneously; the live view being superimposed on the camera live image.

I'm a daily user of this app...and i would say that this easily helped me to locate satellites...just like radars...its worth keeping in my smartphone.
