一个GPS终端，该终端至少应该能实时的显示经度、纬度、海拔高度、当前时间等，并具有一定的扩展能力。-A GPS terminal, the terminal at least should be able to display real-time longitude, latitude, altitude, current time, and has a capacity expansion.

设计预留的功能包括温度、湿度、光照、海拔（气压）、GPS定位、罗盘、风速（需要加风杯和光电管）等-Reserve design features include temperature, humidity, illumination, altitude (pressure), GPS, compass, wind speed (need to add the wind cup and photocell), etc

GPS定位 由于定位最少需要3个卫星，该程序开机就自动搜索上空位置的卫星信号，自动获取当前所在位置的经纬度、时间、海拔高度和移动速度-GPS positioning With positioning requires at least three satellites, the program will automatically boot search over the location of the satellite signals, automatically gets the
