Hi there. I noticed that the sensor=false in your google maps API code. Maybe this is related? I will help review further. - Stephen Blum

Ionic Geo Location Testing

You are getting a security error. User's location and position are protected by browsers. You need to run your project from an HTTP Server. I recommend an HTTPS Server which you can run with one command:

## HTTP(S) Secure Server
python <(curl -L https://goo.gl/Rrko89)

Your static files will be available on https://0.0.0.0:4443/index.html.

Alternatively you can run an insecure HTTP Server by running this command instead:

## HTTP Insecure Server
python -m SimpleHTTPServer

Your insecure static files will be available on http://0.0.0.0:8000/index.html.

Now it will work when you see my screenshot below.

Ionic Geo Location Tracking

To run the code in Cordova PhoneGap you need enable the permissions https://cordova.apache.org/docs/en/2.3.0/cordova/geolocation/geolocation.html

Ionic Cordova PhoneGap Geo Permissions

Android

app/res/xml/config.xml

<plugin name="Geolocation" value="org.apache.cordova.GeoBroker" />

app/AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

iOS

config.xml

<plugin name="Geolocation" value="CDVLocation" />
