Abstract
Recently, with the development of signal processing methods the accuracy of global navigation satellite system (GNSS) services has been improved. However, in urban environment, since the main challenges are multipath, non-line-ofsight (NLOS), weak signals and low accessibility to satellite in the sky, the positioning is unreliable, inaccuracy, therefore, it decreases the potential for various positioning applications. Vector-based tracking has been applied in modern GNSS receivers as the perfect approach instead of conventional tracking. This paper reviews the literature regarding the performance of vector-based methods applied in GNSS receivers under harsh environments. Under a range of conditions, the vector tracking loops demonstrate their robustness against many error sources in GNSS applications. Moreover, the development as well as the application of different methods based on vector tracking loop also rises a promising for further researches. The goad of paper is to provide the state of art relating to vector tracking loop for future approaches in positioning in urban canyons.
