问：Cordova Phonegap地理位置获得正确的速度？

Question

I made an app that tracks users location now i need to get the speed also. I manage to put position.coords.speed but it always shows 0. I noticed that the gps tracker/icon is not actively tracking. What is the best practice on tracking the speed of the user? I am using the plugin cordova-plugin-geolocation

Answer 1

Have you requested high accuracy in the options when requesting location? For example:

navigator.geolocation.watchPosition(onSuccess, onError, {
  enableHighAccuracy: true,
  timeout: 30000,
  maxAge: 0
});

If position.coords.speed is zero and the gps/location icon is not shown in the taskbar, this might be the cause.
