What's new in this version (2.44):

Remembers file and satellite selection.
Minor fixes.


DroidSat is a real-time satellite tracker.

Point your handset at the sky and see which satellites are there.

Because of DroidSat's minimal interface and complicated configuration, it is suitable for advanced users such as radio amateurs and satellite enthusiasts.

If you want a user-friendly satellite viewer with a beautiful interface, I highly recommend star3map (or Space Junk, the lite version of star3Map).

Key features of DroidSat:

- after satellite files have been downloaded, no network connection is required.
- ability to load your own satellite TLE files.
- highly configurable display settings can minimize CPU use and save power.
- fast forward and orbital path display to show future satellite positions.

Enable GPS location and your internet connection before starting it for the first time.

Menu functions:
menu->choose tles - select the category of satellite to display (stations.txt for ISS, visual.txt for the brightest satellites, tle-new.txt for recent launches)
menu->playback speed - speed up display by a factor of 10, 30 or 60.
menu->updated tles - update the satellite database. Do this once a week, or after new satellite launches.
menu->preferences - change your display properties (colours, etc.)

You may also copy your own TLE files to

DroidSat is GPL. Source code available at

DroidSat uses Horst Meyerdierks' Sputnik 3.1 java program for satellite position calculations.

Love it... Droid Incredible. Could use a dark red screen mode to preserve night vision better.

Marko (****)
It is critical to get the distance (slant range) when having radio amateur communications. Please add range.

Emile (*****)
Great app. Simple yet effective.

Mike (*****)
Camera control for video mode. Tin foil hat not included.

Dave (**)
Why do you need camera control? No way.

Mike (*)
No idea how to use this app... uninstalling

Matthew (**)
Odd app. Potential is great though.

Michael (***)
Quirky interface but interesting, useful. Bug, list of sats uses white font on white bkgd-can see entry when selected.

Would like to be able to search for a specific satellite to assist in aiming satellite dishes. Would greatly improve ability to see the sight lines.
