The Power of TeleNav Unveiled
How TeleNav Works
GPS satellites do not actually pinpoint your location as is commonly believed. The 24 satellites circling the earth each contain a precise clock that transmits the time to the GPS receiver in your phone. Your mobile device processes the satellite signals to determine geometrically where you are.
When you make a request for directions, the signal goes from your handset through a cell phone tower to the TeleNav servers. TeleNav immediately pulls up the relevant maps, businesses, gas prices, etc. and send this information back through the cell phone towers to your handset.
TeleNav's Unique Architecture
TeleNav's thin-client (cell phone) and server architecture provides several unique advantages not found in traditional in-car or stand-alone GPS systems.
Since the computational and storage power of TeleNav's industrial-strength servers far exceeds that of a self-contained GPS unit, TeleNav is able to provide a richer user experience.
Here are a few examples:
- TeleNav regularly updates its servers with the latest maps, business listings and other premium content elements. TeleNav users benefit without ever having to purchase and perform manual software updates.
- TeleNav's architecture incorporates both the Internet and speech-recognition technology into the navigational experience. This lets TeleNav users conveniently preplan their trips online and enter a destination through a voice call.
- By leveraging both the wireless carriers' assisted-GPS technology and GPS satellites, TeleNav can determine the user's location much more quickly compared to traditional GPS systems.
TeleNav has received several patents (and many more pending) related to the core technology that allows for mobile phone navigation and tracking. These patents address key challenges in mobile phone navigation, such as low computation power and small memory size of mobile phones, network latency and poor GPS location accuracy in challenging city environments.
