GPS-PFD，利用 GPS 与加速计，在移动设备上模拟飞机驾驶舱的 PFD。
GPS-PFD simulates the cockpit PFD (Primary Flight Display) on mobile devices, by using GPS and accelerometer.
备注：这里的「GPS」指的是位置服务，其利用以 GPS 为代表的卫星导航系统 (GNSS)来精确定位。卫星导航系统包括美国 GPS、俄罗斯 GLONASS，以及中国北斗等。加速计亦称加速度传感器、重力感应器，用于测量姿态、速度与高度。
Note: The "GPS" here stands for location services. Location services use GNSSes such as GPS to precisely locate your position. The most widely used GNSSes include GPS from the US, GLONASS from Russia, Beidou from China, etc. Accelerometer is used to measure attitude, speed and altitude.
建议在搭载了 GPS 芯片与加速计的移动设备（智能手机或平板电脑）上使用本应用程序。否则核心功能可能不可用。在交通工具上可能需要靠窗才能接收到 GPS 信号。GPS 可能会非常耗电，因此建议使用时连接移动电源（充电宝）。
It is recommended that you use this application on a mobile device (smartphone or tablet) with a GPS chip and an accelerometer. Otherwise the basic features may become unavailable. On a vehicle you may have to stay near a window to receive GPS signal. Besides, GPS may be power hungry. It is recommended to connect your device to a power bank while using the application.
