Wireless-based positioning adjustments using a motion sensor

摘要

Apparatuses and methods for adjusting wireless-derived positions of a mobile station using a motion sensor are presented. One method includes estimating a position of a mobile station based upon wireless signal measurements and measuring a movement of the mobile station using a relative motion sensor. The method further includes detecting a displacement of the mobile station based upon the measured movement, determining that the displacement is below a threshold and then adjusting the estimated position of the mobile station using information from the relative motion sensor. An apparatus includes a wireless transceiver, a relative motion sensor, a processor coupled to the wireless transceiver and the relative motion sensor, and a memory coupled to the processor. The memory stores executable instructions and data for causing the processor to execute methods for adjusting wireless-derived positions using a motion sensor.

主权项

1. A method for adjusting a wireless-based position estimate of a mobile station using a relative motion sensor, comprising:
estimating a position of a mobile station based upon wireless signal measurements; detecting a displacement of the mobile station using the relative motion sensor; adjusting an estimated processing delay of a wireless access point using the detected displacement; and refining the estimated position of the mobile station using the adjusted processing delay.
