Look4Sat: Satellite Tracker is an Android application designed to assist users in tracking satellite passes with precision. This free utility falls under the Utilities & Tools category and is developed using modern programming approaches, ensuring both reliability and efficiency. Users can access a vast database of over 5,000 active satellites, sourced from Celestrak and SatNOGS, allowing for easy searches by satellite name or NORAD catalog number. To enhance accuracy, the app calculates satellite positions relative to the user's specific location, which can be set through GPS or QTH Locator settings.

The application features advanced capabilities such as predicting satellite positions and passes for up to a week in advance. Users can view lists of current and upcoming satellite passes, track active passes, and examine polar trajectories. The app also presents detailed satellite positional data, including footprint and ground track visualizations on a map. Custom TLE data can be imported for personalized tracking, and calculations are performed offline, with weekly TLE updates advised for optimal performance. This ad-free, open-source tool is well-suited for enthusiasts and professionals in satellite tracking.

The very app creation and design is hugely inspired by the open-source Gpredict desktop satellite tracking application, created by Alexandru Csete, OZ9AEC and contributors, supported by the Libre Space Foundation.

The Libre Space Foundation team is also behind the epic SatNOGS project that provides an extremely easy to use API and DB with a huge amount of information about satellites, their telemetry and transmitters, which the app uses under the hood.

For TLE data calculation and passes prediction Look4Sat uses the mavenized version of predict4java library, created by David A. B. Johnson, G4DPZ and Dave Moten. Thank you guys for your hard work making this lib efficient and easy to use!

https://github.com/davidmoten/predict4java

The app is built using Dagger2, Retrofit2, Kotlin and Kotlin coroutines, Architecture Components and Jetpack Navigation.

Main features:

Calculating satellite passes for up to one week (168 hours)

Calculating passes for the current or manually entered location

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

Offline first: all the passes predictions are made offline. It's up to you to decide when to update the TLE file and the transceivers DB. (Updates once a week are recommended)
