Trusted Portable Navigator (T-PN)
The Trusted Portable Navigator (T-PN) offers a software solution that uses existing hardware in mobile devices to provide continuous and accurate location and navigation in any environment.
The T-PN software turns low-cost MEMS inertial sensor signals from the device into seamless navigators that work with any wireless signal update such as GPS and Wi-Fi.
Advantages
The T-PN provides the following advantages:
- Provides navigation information in any environment
- The mobile device can be used in any orientation with respect to the platform of motion (i.e. person or vehicle)
- Provides both mobile device and platform orientation
- Seamless transitions between different modes of transportation, such as walking and driving
- Differentiates between types of movement such as walking, driving, and stopped
- Ability to flag movement abnormalities such as falling, prolonged stillness, and fidgeting
