In the age of automation the ability to navigate persons and devices in indoor environments
has become increasingly important for a rising number of applications. With the emergence …

In recent years, tremendous advances have been made in the design and applications of
wireless networks and embedded sensors. The combination of sophisticated sensors with …

In regions where global navigation satellite systems (GNSS) signals are unavailable, such
as underground areas and tunnels, GNSS simulators can be deployed for transmitting …

In positioning technology, indoor positioning is known as the “last kilometer” problem
because the global navigation satellite system (GNSS) cannot work indoors. A wide range of …

Despite the wide use of the global navigation satellite system (GNSS), its performance can
be severely degraded due to blockage and vulnerability to interference. Stand-alone ground …

We present a hybrid indoor positioning solution combining angle-based localization,
pedestrian dead reckoning, and map filtering. The angle-based localization system provides …

为提升伪卫星在室内多径环境中的定位精度, 根据室内伪卫星载波多径的时空变化特征建立了一
种基于用户空间位置的多径误差改正模型. 首先提取静态采样点的载波双差多径误差值 …

In the absence of a global navigation satellite system, a ground-based positioning system
can provide stand-alone positioning service and has advantages in layout flexibility of …

In this paper, an indoor positioning system using Global Positioning System (GPS) signals in
the 433 MHz Industrial Scientific Medical (ISM) band is proposed, and an experimental …

视觉惯性里程计(VIO) 和伪卫星已经广泛应用于室内环境定位中, 但在实际应用中,
二者各自都有明显的缺陷. 视觉里程计依赖于实际场景, 在景深变化明显和光照不均匀的环境下 …
