+### GPSRelaySentinel 应用描述
+
+#### 中文描述 ：
+GPSRelaySentinel 是一款专业的 GPS 定位中继守护工具，支持真实系统 GPS 定位监听与模拟 GPS 坐标仿真双模式运行。应用后台常驻前台服务，实时接收系统 GPS 位置数据，内置订阅者步长阈值判断机制，可对多个 GPS 订阅视图进行定点推送管理。
+提供可视化模拟控制面板，支持选择八大方位、自定义模拟移动距离，自动计算偏移目标经纬度；配备模拟模式勾选开关，可一键切换真实 GPS 工作模式与虚拟仿真模式。模拟状态下系统会接管自定义模拟坐标，忽略原生真实定位数据；普通模式则正常使用设备 GPS 原始位置。
+界面采用深色极简风格，全控件灰色文字与灰色边框统一视觉设计，集成日志实时输出面板，方便调试定位轨迹与订阅推送状态，适合定位开发测试、虚拟位置仿真、GPS 中继转发等场景使用。

+#### English Description :
+GPSRelaySentinel is a professional GPS relay and guardian tool, supporting dual modes of real system GPS location monitoring and simulated GPS coordinate simulation. It runs as a foreground persistent background service, receives real-time system GPS location data, and builds-in subscriber step threshold judgment mechanism to manage fixed-point push for multiple GPS subscription views.
+It provides a visual simulation control panel, supports eight direction selections and custom simulated moving distance, and automatically calculates offset target latitude and longitude. With a simulation mode checkbox, you can one-click switch between real GPS working mode and virtual simulation mode.
+In simulation mode, the app takes over custom simulated coordinates and ignores original real location data; in normal mode, it uses the device’s native GPS position normally. The UI adopts a dark minimalist design with unified gray text and gray borders for all controls, and integrates a real-time log output panel for debugging location tracks and subscription push status. It is suitable for location development testing, virtual position simulation, GPS relay forwarding and other scenarios.
