"AlwaysOnGPS enables standard GPS users with WiFi enabled PocketPC/PDA devices to determine their precise location (GPS coordinates) in situations where and when GPS signals are not available. Using the power of our advanced (patent pending) WiFi Positioning System, GPS users with WiFi enabled devices can still access extremely accurate GPS Data while located or situated: within office buildings, warehouses, campus interiors, clubs, restaurants, museums, galleries, conference facilities, newly discovered venues, between tall buildings, within "urban canyons", inside multi-level car parking decks and even underground!"



This seems like a great solution for those of you who suffer from signal loss problems (usually present in heavily built-up settings). As soon as the signal drops out, AlwaysOnGPS makes full use of Wi-Fi positioning to provide a continuous and accurate data feed. There is a 30-day trial if you're interested, and a single license is priced at $19.95.
