Inertial Positioning to Reduce Power Consumption in GPS Watches



Inertial Positioning to Reduce Power Consumption in GPS Watches
Invensense, a manufacturer of semiconductors that specializes in motion sensing has announced at the Mobile World Congress in Barcelona a solution to solve the problem of poor battery life on sport and fitness watches.

Manufacturers of sport - or smart - watches are constrained by the size of their device hence the battery in one hand and in the other hand by the power consumption of GPS apps. To solve this power problem Invensense offers an inertial navigation software that calculates the position of the device based on its movements between two GPS fixes. Therefore GPS does not need to run continuously.

This can expands the battery life from two to five times, according to Invensense.

This inertial positioning system was developed by Trusted positioning, a start-up company from Calgary, Canada, bought by Invensense last summer.
