Wireless-based positioning adjustments using a motion sensor

An apparatus for adjusting a wireless-based position estimate of a mobile station using a relative motion sensor, comprising:

• 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, wherein the memory stores executable instructions and data for causing the processor to
• estimate a position of a mobile station based upon wireless signal measurements,
• detect a displacement of the mobile station using a relative motion sensor,
• adjust an estimated processing delay of a wireless access point using the detected displacement, and
• refine the estimated position of the mobile station using the adjusted processing delay.

An apparatus for adjusting a wireless-based position estimate of a mobile station using a relative motion sensor, comprising:

• means for estimating a position of a mobile station based upon wireless signal measurements;
• means for detecting a displacement of the mobile station using the relative motion sensor;
• means for adjusting an estimated processing delay of a wireless access point using the detected displacement;
• and
• means for refining the estimated position of the mobile station using the adjusted processing delay.

A machine-readable medium comprising instructions, which, when executed by a machine, cause the machine to perform operations, the instructions comprising:

• instructions to estimate a position of a mobile station based upon wireless signal measurements;
• instructions to detect a displacement of the mobile station using a relative motion sensor;
• instructions to adjust an estimated processing delay of a wireless access point using the detected displacement;
• and
• instructions to refine the estimated position of the mobile station using the adjusted processing delay.
