A single base station position location approach for enhanced-911

The FCC issued Docket No. 94-102 and 1996-97 rulemaking orders which will require wireless providers to locate emergency 911 calls to 125 meter accuracy by late 2001. Current first and second generation cellular networks are designed to maximize quality of service at the base station servicing a user. Most position location approaches require measurements at multiple receiving stations. This requirement is counter to the cellular network design that assigns one base station to service a given user. A new approach is proposed which uses single base station angle of arrival measurements and vehicle speed and heading to perform wireless position location. Simulation results show that this approach can outperform a multiple base station approach
