GPS AND MEMS HYBRID LOCATION-DETECTION ARCHITECTURE |
摘要 |
<p>The present application describes a computer-implemented method and system for obtaining position information for a moving mobile device with increased accuracy ars.d reduced power consumption. The subject of the present application combines information from a GPS location sensor with information from MEMS devices such as an acceleration detector and a gyroscope using statistical analysis techniques such as a Kalman filter to estimate the location of the device with greater accuracy while using numerical, methods such as the Newton-Raphson Method to minimize power consumption. Minimizing power consumption is possible because GPS signals sampled at a lower rate can conserve power, while GPS sampled at a lower rate and working together with MEMS devices can achieve the same level of location prediction accuracy as a GPS alone sampled at a higher rate.</p> |
