Abstract

A highly compact and secure municipal area personnel tracking device is described. Position updates to a nominal accuracy of 20 meters for up to 1000 active users are required. Coverage over paging and cellular phone service areas, including most interior office space, is provided. The system is protected from unauthorized position monitoring and from jamming. Dependent tracking and independent tracking are considered. The selected tracking system uses a user beacon operating in the 900 MHz range, the signal emitted by each user consisting of 0.1-s bursts sent every 100 s. A time-bandwidth of 100000 is utilized to overcome high link attenuations and interference. To meet spoof and position-denial requirements, one-time bursts are used in each time slot. A custom all-digital signal correlation system was developed to meet the high processing gain and programmability requirements of master and remote monitor sites. Acquisition times are reduced by transmit time and time interval synchronization obtained over the existing paging or cellular-phone receive link.<>

用于嵌入式寻呼、移动电话和执法应用的高性能位置跟踪器

介绍了一种高度紧凑、安全的市政区域人员跟踪装置。需要多达1000个活跃用户的位置更新标称精度为20米。覆盖寻呼和移动电话服务区，包括大部分内部办公空间。该系统可以防止未经授权的位置监控和干扰。考虑了依赖跟踪和独立跟踪。所选择的跟踪系统使用900 MHz范围内的用户信标，每个用户发出的信号由每100 s发送0.1 s的脉冲组成。利用10万的时间带宽克服高链路衰减和干扰。为了满足欺骗和位置拒绝的要求，在每个时隙中使用一次突发。为了满足主站和远程监控站点的高处理增益和可编程性要求，开发了定制的全数字信号相关系统。通过现有寻呼或蜂窝电话接收链路获得的传输时间和时间间隔同步减少了采集时间。
