Look4Sat: Satellite Tracker - A Powerful Tool for Tracking Satellites
Look4Sat: Satellite Tracker is an Android application designed for tracking satellite passes with ease. Developed by Arty Bishop, this app is available for free in the Utilities & Tools category. The application is built using Kotlin, Coroutines, Architecture Components, and Jetpack Navigation, making it reliable and efficient.
Thanks to the massive database provided by Celestrak and SatNOGS, the app provides access to more than 5000 active satellites orbiting Earth. You can search the entire database by satellite name or by NORAD catnum. The satellite positions and passes are calculated relative to your location. To get reliable information, make sure to set the observation position using GPS or QTH Locator in the Settings menu.
One of the main features of this application is predicting satellite positions and passes for up to a week. Additionally, it shows the list of currently active and upcoming satellite passes, active pass progress, polar trajectory, and transceivers info. The application also displays the satellite positional data, footprint, and ground track on a map. Custom TLE data import is available via files with TXT or TLE extensions. The calculations are made offline, and weekly updates of TLE data are recommended. This ad-free and open-source application is a must-have for anyone interested in satellite tracking.
