Rafael Rivera and Long Zheng have released a handy application for Windows 7 called Geosense, a Windows Sensor, that provides the Location and Sensors platform in Windows 7 with accurate and reasonably ubiquitous positioning information without requiring or the assistance of GPS hardware, enabling more practical location-based applications and scenarios on Windows 7.
Geosense is available for both x86 & x64 versions of Windows 7. You can download the setup file from the link mentioned below. More information is available at the Geosense download page and articles on Rafael Rivera and Long Zheng‘s blog.
