You can use bower to install ngCordova like so or download the zip file here, and locate the .js file in the dist folder:

 $ bower install ngCordova

Include ng-cordova.js or ng-cordova.min.js in your index.html file before cordova.js and afteryour AngularJS / Ionic file (since ngCordova depends on AngularJS).

angular.module('myApp', ['ngCordova'])
