# Satellite Tracker / 卫星追踪器

**Real-time satellite tracking for AI agents — no API key required.**
实时卫星追踪 —— 无需 API Key，开箱即用。

## When to Use / 何时使用

- User asks where a satellite or space station is / 用户问某颗卫星/空间站在哪
- User asks about Tiangong (CSS) or ISS location / 用户问天宫空间站或ISS位置
- User wants to track a spacecraft after launch / 用户想追踪发射后的航天器
- User wants satellite pass predictions / 用户想看卫星过境时间
- User is following a launch mission / 用户追踪发射任务

## Installation / 安装

```bash
pip install sgp4
```

## Usage / 用法

```bash
# Real-time position by name / 按名称查询
python3 skills/satellite-tracker/track.py --name 天宫
python3 skills/satellite-tracker/track.py --name ISS

# Real-time position by NORAD ID / 按NORAD ID查询
python3 skills/satellite-tracker/track.py --id 48274

# Pass predictions (requires observer coordinates) / 过境预测（需要观测者坐标）
python3 skills/satellite-tracker/track.py --name 天宫 --observer 28.2,112.9 --passes 5

# List all known satellites / 列出所有已知卫星
python3 skills/satellite-tracker/track.py --list

# Update TLE cache / 更新TLE缓存
python3 skills/satellite-tracker/track.py --update

# Continuous tracking mode / 持续追踪模式
python3 skills/satellite-tracker/track.py --name 天宫 --watch 60

# JSON output / JSON输出
python3 skills/satellite-tracker/track.py --name 天宫 --json
```

## Known Satellites / 已知卫星

| Name / 名称 | NORAD ID | Description / 说明 |
|---|---|---|
| 天宫 (Tiangong/CSS) | 48274 | 中国空间站 Chinese Space Station |
| ISS | 25544 | 国际空间站 International Space Station |
| 哈勃 (Hubble) | 20580 | 哈勃太空望远镜 Hubble Space Telescope |

New satellites (e.g. Tianzhou cargo spacecraft) get assigned NORAD IDs after launch.
Use `--update` to refresh TLE data, then search by ID.
天舟等新航天器发射后会分配NORAD ID，用 `--update` 更新后可追踪。
