三个用户反馈一并解决: 1. 解码文字不再消失 (核心) 旧实现: 20 秒环形缓冲满了就静默覆盖最旧样本, 文字随之从屏幕消失。 新实现: CwDeepBuffer 新增 overflow —— 满时被覆盖的旧样本先进 overflow, 解码器累积到 15 秒就单独解码一次, 结果追加到 historyText (只增不减)。 UI 记录区显示 historyText + decodedText (历史稳定 + 当前窗口实时)。 ICwDecoder 接口新增 historyText StateFlow。 归档音频已离开主窗口, 不再被 CTC 修正, 故其文本是"最终版", 追加安全。 归档窗口 15 秒: 内容已在 20 秒窗口里解过多次, 短一点几乎无损, 且推理 开销小。 2. 瀑布图更好看 配色从"深蓝->青->黄"换成 matplotlib inferno (黑->紫->品红->橙->黄), 与静态频谱图保持一致。相邻 bin 之间用水平渐变做线性插值, 消除 65 列 离散方块的像素感。 3. AGPL 合规补漏 (用户提醒: 仓库许可证没体现 AGPL 组件) README 新增 License 章节: 声明项目主体 GPL-3.0 + feature/cw 的 DeepCW 模型 AGPL-3.0-only, 并说明合并作品按 GPL-3.0 §13 / AGPL-3.0 §13 处理。 验证: - :core:domain:test => 31 个 CW 测试全绿 (CwDeepBufferTest 新增 3 个 overflow 归档测试: 顺序/清空/reset) - :core:domain:compileKotlin + :core:data + :feature:cw:compileDebugKotlin => BUILD SUCCESSFUL

### 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.
