Look4Sat: Satellite tracker

Arty Bishop

About this app

Track satellite passes with ease!

Thanks to Celestrak and SatNOGS you have access to over 9000 active satellites.
You can search the entire database by NORAD Catalog Number or the satellite's name.

Orbital positions and passes are calculated relative to your location.
To get reliable data make sure to set the station position via the app Settings.

The application is built using Kotlin, Coroutines, Jetpack Compose and Navigation.
It is now and always will be completely ad-free and open-source.

Main features:
- Predicting satellite positions and passes for up to 10 days
- 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 the map
- Custom TLE satellite data import is available via Three Line Element .txt files
- Offline first: calculations are made offline. Weekly TLE data update is recommended.

Ratings and reviews

This app looks great! However it is a bit challenging to interpret the frequencies for linear repeaters. It would be better if the range for both uplink and downlink were displayed (which can be much wider than typical 3 kHz SSB). Also, frequencies are displayed reversed from common nomenclature (typically I see uplink/downlink, e.g. in terminology like V/U, but this app uses the order downlink/uplink).

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.
