-# 卫星预测轨道显示功能
-
-## TL;DR
-> 锁定卫星时显示绕地球完整一圈的预测轨道轨迹，从当前位置向外渐变消失
-
-## Context
-
-### 目标
-点击锁定卫星 → 显示该卫星绕地球一周的完整预测轨道（而非当前的历史轨迹）
-
-### 当前实现
-- `TRAIL_LENGTH = 30` - 历史轨迹点数，每帧 push 当前位置
-- 显示最近30帧历史轨迹（类似彗星尾巴）
-
-### 参考: SatelliteMap.space
-- 锁定时显示预测轨道
-- 颜色从当前位置向外渐变消失
-- 使用 satellite.js（与本项目相同）
-
-## 实现状态
-
-### ✅ 已完成
-- [x] 计算卫星轨道周期（基于 `meanMotion`）
-- [x] 生成预测轨道点（10秒采样间隔）
-- [x] 创建独立预测轨道渲染对象
-- [x] 锁定卫星时显示预测轨道
-- [x] 解除锁定时隐藏预测轨道
-- [x] 颜色渐变：当前位置(亮) → 轨道终点(暗)
-- [x] 页面隐藏时清除轨迹（防止切回时闪现）
-
-### 🚧 进行中
-- [ ] 完整圆环轨道（部分卫星因 SGP4 计算问题使用 fallback 圆形轨道）
-- [ ] 每颗卫星只显示一条轨道
-
-## 技术细节
-
-### 轨道周期计算
-```javascript
-function calculateOrbitalPeriod(meanMotion) {
-  return 86400 / meanMotion;
-}
-```
-
-### 预测轨道计算
-```javascript
-function calculatePredictedOrbit(satellite, periodSeconds, sampleInterval = 10) {
-  const points = [];
-  const samples = Math.ceil(periodSeconds / sampleInterval);
-  const now = new Date();
-  
-  // Full orbit: from now to now+period
-  for (let i = 0; i <= samples; i++) {
-    const time = new Date(now.getTime() + i * sampleInterval * 1000);
-    const pos = computeSatellitePosition(satellite, time);
-    if (pos) points.push(pos);
-  }
-  
-  // Fallback: 如果真实位置计算点太少，使用圆形 fallback
-  if (points.length < samples * 0.5) {
-    points.length = 0;
-    // ... 圆形轨道生成
-  }
-  
-  return points;
-}
-```
-
-### 渲染对象
-```javascript
-let predictedOrbitLine = null;
-
-export function showPredictedOrbit(satellite) {
-  hidePredictedOrbit();
-  // ... 计算并渲染轨道
-}
-
-export function hidePredictedOrbit() {
-  if (predictedOrbitLine) {
-    earthObjRef.remove(predictedOrbitLine);
-    predictedOrbitLine.geometry.dispose();
-    predictedOrbitLine.material.dispose();
-    predictedOrbitLine = null;
-  }
-}
-```
-
-## 已知问题
-
-### 1. TLE 格式问题
-`computeSatellitePosition` 使用自行构建的 TLE 格式，对某些卫星返回 null。当前使用 fallback 圆形轨道作为补偿。
-
-### 2. 多条轨道
-部分情况下锁定时会显示多条轨道。需要确保 `hidePredictedOrbit()` 被正确调用。
-
-## 性能考虑
-
-### 点数估算
-| 卫星类型 | 周期 | 10秒采样 | 点数 |
-|---------|------|---------|------|
-| LEO | 90分钟 | 540秒 | ~54点 |
-| MEO | 12小时 | 4320秒 | ~432点 |
-| GEO | 24小时 | 8640秒 | ~864点 |
-
-### 优化策略
-- 当前方案（~900点 GEO）性能可接受
-- 如遇性能问题：GEO 降低采样率到 30秒
-
-## 验证方案
-
-### QA Scenarios
-
-**Scenario: 锁定 Starlink 卫星显示预测轨道**
-1. 打开浏览器，进入 Earth 页面
-2. 显示卫星（点击按钮）
-3. 点击一颗 Starlink 卫星（低轨道 LEO）
-4. 验证：出现黄色预测轨道线，从卫星向外绕行
-5. 验证：颜色从亮黄渐变到暗蓝
-6. 验证：轨道完整闭环
-
-**Scenario: 锁定 GEO 卫星显示预测轨道**
-1. 筛选一颗 GEO 卫星（倾斜角 0-10° 或高轨道）
-2. 点击锁定
-3. 验证：显示完整 24 小时轨道（或 fallback 圆形轨道）
-4. 验证：点数合理（~864点或 fallback）
-
-**Scenario: 解除锁定隐藏预测轨道**
-1. 锁定一颗卫星，显示预测轨道
-2. 点击地球空白处解除锁定
-3. 验证：预测轨道消失
-
-**Scenario: 切换页面后轨迹不闪现**
-1. 锁定一颗卫星
-2. 切换到其他标签页
-3. 等待几秒
-4. 切回页面
-5. 验证：轨迹不突然闪现累积
