getLocation和onLocationChange定位，前后几秒存在500米误差？

-【公司的同事也复现了这个问题，我们可以上传今天的调用日志协助API开发者排查问题】- 以下是API的主要调用方式：  wx.getLocation({    type: 'gcj02',    success: res => {},    fail: res => {}  })  wx.startLocationUpdate()  wx.onLocationChange(res => {})-以下是线上用户的日志（getLocation和onLocationChange的返回记录，分别在两个数组里，有时间戳）：    "onLocationChangeLogStack": [      {        "log": "第0项日志",        "logContent": {          "altitude": 0,
