本研究讨论了一个简单的多传感器多网络定位系统，该系统集成了全球定位卫星（GPS）测量、加速度计和数字指南针，并利用行人运动模型和航位推算进行无线网络定位。讨论了多技术系统实现室内外无缝行人导航的可行性，重点讨论了系统的可靠性问题和适应性要求。多传感器多网络定位系统是为室内和城市峡谷等具有挑战性的导航环境而开发的。本文研究了如何估计和提高多传感器多网络系统的可靠性，并估计其精度。进行了室外到室内的行人试验。展示了多技术解决方案的自适应滤波性能，以及在过度确定解决方案时的一般测量质量监控和误差检测。提出了利用环境检测形式的自适应来估计最终定位精度的可靠性估计方法。
This study discusses a simple multi-sensor multi-network positioning system that integrates global positioning satellite (GPS) measurements, accelerometers and a digital compass with wireless network localisation utilising a pedestrian motion model and dead reckoning. The feasibility of the multi-technology system for seamless outdoor to indoor pedestrian navigation is discussed with the emphasis on reliability issues and adaptability requirements. The multi-sensor multi-network positioning system is developed for challenging navigation environments such as indoors and deep urban canyons. This study considers how to estimate and improve such a multi-sensor multi-network system's reliability and estimate its accuracy. An outdoor to indoor pedestrian test is conducted. Adaptive filtering performance of the multi-technology solution as well as general measurement quality monitoring and error detection when an over-determined solution is at hand is shown. Reliability estimation utilising adaptation in the form of environment detection to estimate the final positioning accuracy is also presented.
