摘要: Authors presented recently an indoor location technique based on Time Of Arrival (TOA) obtained from Round-Trip-Time (RTT) measurements at data link level and trilateration. This new approach uses the existing IEEE 802.11 WLAN infrastructure with minor changes to provide accurate estimation of position static wireless terminals. paper presents advances how incorporate tracking capabilities this in order achieve a noticeable enhancement positioning accuracy while maintaining computational cost low, both essential requirements some critical applications pedestrian navigation which people carrying light mobile devices has be tracked precision. Taking as basis Discrete Kalman Filter, customizations optimizations have been designed presented. Results after conducting extensive simulations fed actual ranging observables demonstrate validity suitability researched algorithms its ability very high performance terms robustness.
