用户指出 GitHub 上显示的许可证仍是 GPL-3.0,未反映合并 AGPL 组件的事实。 根因: 之前只在 README 加了 License 章节,根 LICENSE 文件仍是 GPL-3.0 原文, GitHub 的自动检测(只扫 LICENSE 文件)自然还是 GPL-3.0。 修复: 合并作品按 GPL-3.0 §13 / AGPL-3.0 §13 处理,根 LICENSE 改为: - 顶部 LICENSING NOTICE 说明构成 (Look4Sat 代码 GPL-3.0 + DeepCW 模型 AGPL-3.0-only, 合并作品按 AGPL-3.0 分发) - 正文为 AGPL-3.0 原文 (从 DeepCW-AGPL-3.0.txt 复制) 原 GPL-3.0 原文保留在 feature/cw/licenses/Look4Sat-GPL-3.0.txt。 README License 章节同步更新,与新 LICENSE 一致。 此后 GitHub 侧边栏将识别为 AGPL-3.0。

### Track satellite passes with ease!
|
|
|
|
Thanks to [Celestrak](https://celestrak.com/) and [SatNOGS](https://satnogs.org/) 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.
