描述
简介
移动终端设备已经深入人们日常生活的方方面面，如查看所在城市的天气、新闻轶事、出行打车、旅行导航、运动记录。这些习以为常的活动，都离不开定位用户终端设备的位置。
当用户处于这些丰富的使用场景中时，系统的位置定位能力可以提供实时准确的位置数据。对于开发者，设计基于位置体验的服务，也可以更好的满足用户的需求。
当应用在实现基于设备位置的功能时，如：驾车导航，记录运动轨迹等，可以调用该模块的API接口，完成位置信息的获取
基本概念
位置能力用于确定用户设备在哪里，系统使用位置坐标标示用户设备的位置，并使用多种定位技术提供位置服务，如GNSS定位、基站定位、WLAN/蓝牙定位（基站定位、WLAN/蓝牙定位后续统称“网络定位技术”）。通过这些定位技术，无论用户设备在室内或是户外，都可以准确地确定用户设备的位置。
- 坐标
系统以1984年世界大地坐标系统为参考，使用经度、纬度数据描述地球上的一个位置。 - GNSS定位
基于全球导航卫星系统，包含：GPS、GLONASS、北斗、Galileo等，通过导航卫星，设备芯片提供的定位算法，来确定设备准确位置。定位过程具体使用哪些定位系统，取决于用户设备的硬件能力。 - 基站定位
根据设备当前驻网基站和相邻基站的位置，估算设备当前位置。此定位方式的定位结果精度相对较低，并且需要设备可以访问蜂窝网络。 - WLAN、蓝牙定位
根据设备可搜索到的周围WLAN、蓝牙设备位置，估算设备当前位置。此定位方式的定位结果精度依赖设备周围可见的固定WLAN、蓝牙设备的分布，密度较高时，精度也相较与基站定位方式更高，同时也需要设备可以访问网络。

约束
- 使用设备的位置能力，需要用户进行确认并主动开启位置开关。如果位置开关没有开启，系统不会向任何应用提供位置服务。
- 设备位置信息属于用户敏感数据，所以即使用户已经开启位置开关，应用在获取设备位置前仍需向用户申请位置访问权限。在用户确认允许后，系统才会向应用提供位置服务。
