This Small Business Innovative Research Phase II project from Signatron is focused on a novel radiolocation technology lowering the costs to the public of determining the location of cellular telephones which place emergency calls. The new technology involves a proprietary technique for collection of the calling phone signal parameters at two or more base stations which are then transmitted to a central computer for position computation. In Phase I, mathematical analysis and computer simulations were used to prove the technical feasibility of the technique. Not only was the technique shown to be feasible, but it was shown to be much more accurate and an order of magnitude less costly than the existing state of the art. In Phase II, a prototype system, comprising base stations linked to a central position location computer, will be integrated into a commercial cellular telephone system to further refine and evaluate the technology in field operation. Besides the important application to emergency cellular phone location (E911), this new technology will have a number of applications in other location based services for which current geolocation technologies are either ineffective or too expensive. Such services include location based billing for wireless telephones, locating fraudulent phone callers, vehicle fleet management, tracking of parolees, child location, location of wandering Alzheimer's disease patients, location of stolen vehicles, location of stolen equipment such as lap-top computers, and location of lost pets.

Signatron的这个小企业创新研究第二阶段项目专注于一种新的无线电定位技术，降低了公众确定发出紧急呼叫的蜂窝电话的位置的成本。这项新技术涉及一种专有技术，用于在两个或更多个基站收集主叫电话信号参数，然后将这些参数传输到中央计算机进行位置计算。在第一阶段，使用数学分析和计算机模拟来证明该技术的技术可行性。这项技术不仅被证明是可行的，而且被证明比现有的技术水平更准确，成本低一个数量级。在第二阶段，一个原型系统，包括连接到中央定位计算机的基站，将被集成到一个商业蜂窝电话系统中，以便在外地业务中进一步改进和评估这项技术。除了在紧急蜂窝电话定位(E911)中的重要应用外，这项新技术还将在其他基于位置的服务中有许多应用，目前的地理定位技术对这些服务要么无效，要么过于昂贵。这些服务包括无线电话的基于位置的账单、定位欺诈性电话呼叫者的位置、车队管理、跟踪假释犯、儿童位置、流浪的阿尔茨海默病患者的位置、被盗车辆的位置、笔记本电脑等被盗设备的位置以及丢失宠物的位置。
