### Let this app look for satellites for you!
|
|
|
|
Thanks to the huge database provided by Celestrak and SatNOGS you have access to more than 3000
|
|
active satellites orbiting Earth at this very moment. You can search the entire DB by satellite
|
|
name or by NORAD catalog number. Track them with ease!
|
|
|
|
Satellite positions and passes are calculated relative to your location. In order to get reliable
|
|
predictions set the observation position using GPS or QTH Locator in the Settings menu.
|
|
|
|
The application is built using predict4java library, Kotlin, Coroutines, Dagger2, Retrofit2, Moshi,
|
|
Architecture Components and Jetpack Navigation. It is now and always will be completely ad-free
|
|
and open-source.
|
|
|
|
## Main features:
|
|
|
|
* Predicting satellite positions and passes for up to 4 days (96 hours)
|
|
* Showing the list of currently active and upcoming satellite passes
|
|
* Showing the active pass progress, polar trajectory and transceivers info
|
|
* Showing the satellite positional data, footprint and ground track on a map
|
|
* Custom TLE data import is available via files with TXT or TLE extensions
|
|
* Offline first: calculations are made offline. Weekly update of TLE data is recommended.
