Look4Sat: Satellite tracker

About this app

Track satellite passes with ease!

Thanks to the huge database provided by Celestrak and SatNOGS you have access to more than 5000 active satellites orbiting Earth. You can search the entire DB by satellite name or by NORAD catnum.

Satellite positions and passes are calculated relative to your location. To get reliable info make sure to set the observation position using GPS or QTH Locator in the Settings menu.

The application is built using Kotlin, Coroutines, 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 a week
- 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.

Ratings and reviews

A free app - no ads, no nags for a review, no monthly subscription and still being developed. A tip is on the way, thank you. My use case is manually tracking APT and SSTV satellites as they pass over and using a cheap radio handset to listen. Combined with a Yagi, perfect app to track them. Now with reminders I will (hopefully) not miss the ISS when it sends images this coming week. Split screen with Robot36 gives just enough room to scroll frequencies (Pixel 9a) but not on all phones/tablets.

LOVE IT!! I use this application every day for tracking amateur and other satellites! It is accurate on the doppler shift which is extremely helpful! Though, I wish there was a button or something to update satellite data or add a new ones. And, I would like a frequency range filter in the area that you choose the satellites you want. Overall, this is the only tracker I can find that is perfect for me! Thanks alot!!

Great satellite tracking app! Very concise and accurate. Easy-to-use. Nice user interface. Low impact on memory and Battery. Plus, and here's a big one, it has no ads everything you need to know about satellites is installed in this app. I consider it one of the best (if not the best) of its kind out there. It's a keeper and highly recommended.
