Navizon is a software-only wireless positioning system that triangulates signals broadcasted from Wi-Fi access points and Cellular towers to help the users find their way in most major metropolitan areas worldwide.
The Navizon network is based on a collaborative database. Members with a GPS device can use Navizon to map the Wi-Fi and cellular landscape in their neighborhoods. Once they synchronize their data, it is made available to all the other users of the network. This way, users who don't have a GPS device can benefit from a positioning system. And it's free for personal use!
JOHNNY ROCKET a new version for WM2003 came out and it connects to my GPS without issues. I'll be able to start uploading data for my area. yay! (Version 1.1.2)
JOHNNY ROCKET haven't been able to get the java version to recognize my Holux GR-231 gps receiver. But the iPhone version works fine. I did find that you can manually upload data collected by KisMAC and they'll add this to the servers and make it available to everyone. (Version 1.1.2)
