实时定位系统 (RTLS) 的开发已成为许多现有位置感知系统的重要附加组件。虽然 GPS 已经解决了大部分室外 RTLS 问题，但它未能在室内重复这一成功。许多技术已被用来解决室内跟踪问题。准确跟踪室内人员位置的能力具有许多应用，从医疗、军事、后勤到娱乐。然而，当前的系统无法提供对移动目标的连续实时跟踪，或者在覆盖范围较差时失去能力。然而，实时定位系统的部署充满了问题。迄今为止，很少有研究比较市场上的商业系统，以告知 IT 部门其在各个方面的性能，这对于跟踪相对有限区域中的设备和人员非常重要。本文试图通过回顾安装某些位置传感系统的实用性来提供这样一个有用的比较。我们还评论了使用位置传感系统所达到的精度和遇到的问题。
The development of real-time locating systems (RTLS) has become an important add-on to many existing location aware systems. While GPS has solved most of the outdoor RTLS problems, it fails to repeat this success indoors. A number of technologies have been used to address the indoor tracking problem. The ability to accurately track the location of people indoors has many applications ranging from medical, military and logistical to entertainment. However, current systems cannot provide continuous real-time tracking of a moving target or lose capability when coverage is poor. The deployment of a real-time location determination system however is fraught with problems. To date there has been little research into comparing commercial systems on the market with regard to informing IT departments as to their performance in various aspects which are important to tracking devices and people in relatively confined areas. This article attempts to provide such a useful comparison by providing a review of the practicalities of installing certain location-sensing systems. We also comment on the accuracies achieved and problems encountered using the position-sensing systems.
