I'm currently working on some geolocation javascripts, but am unable to test and debug them properly: My desktop machine (Running Windows, with Chrome 5 or Firefox 3) doesn't have location information and my mobile devices don't feature any debugging capabilities.

How can I test geolocation scripts? Is there a tool which will fake a GPS sensor?

+4  A: 

In Firefox, it's possible to switch the default Geolocation provider (Google) to a manually entered source.

Fake your geolocation in Firefox 3.5

All you need for faking is a text file (eg. /home/username/.mynewlocation.txt) somewhere on your computer with the following content: {"location":{"latitude":50.941863,"longitude":6.958374, "accuracy":20.0}}

The path in Firefox to this file is: file://home/username/.mynewlocation.txt

Type about:config in your location bar, confirm the warning, search for geo.wifi.url, and replace the old url (https://www.google.com/loc/json) with your new one from above. Restart firefox, enjoy your new location :-)

And there's a similar SO question with a number of good answers as well.

A: 

the geo-location-javascript library contains a component for simulating locations, you simply add them with:

locations=new Array();
locations.push({ coords:{latitude:41.39985,longitude:2.19610},duration:5000 });
locations.push({ coords:{latitude:41.40,longitude:2.197},duration:5000 });

and the you initialize the component. look under simulation on the homepage
