“…During the rapid development of the global navigation satellite system (GNSS) in the last 20 years, the satellite number of each constellation is increasing, but the service provided by single constellation is not able to meet the user location and navigation needs [1, 2]. At the same time, when receivers work in complex environments such as streets with tall buildings and road intersections, the navigation performance is reduced gravely and traditional receivers tracking loop cannot provide real‐time and accurate positioning information, so it is significant to improve the tracking loop algorithm of receivers [3].…”

“…[5] and [6] propose Kalman Filter based adaptive carrier tracking loops to further improve the ability of weak signal tracking. On the other hand, some methods change the architecture of signal tracking including the vector tracking loop [7], [8] and the open loop tracking method [9], [10]. Ref.…”

“…Although there are many multi-constellation receiver solutions at present, most receivers still keep each channel signal track process independently and recent researches on the baseband signal processing of GNSS receiver are mainly focused on the single-constellation receiver system [4][5][6][7], so the nature correlations between the signals of all channels and receiver's dynamic characteristics have been ignored. To develop the potential performance of the receiver, the first contribution of this paper is that a GPS/ BeiDou combined vector tracking algorithm has been www.ietdl.org investigated based on the mechanism analysis of the vector tracking loop (VTL).…”

“…In addition, the Chinese receiver producer OLinkStar released BeiDou/GPS/GLONASS systems compatible single‐chip, which can provide the positioning, velocity measurement and time service. Compared with receivers based on one constellation, multi‐constellation receivers have many advantages as follows: (a) Able to acquire and track more visible satellites in complex environments such as city canyons or forests. (b) Able to improve dilution of precision (DOP) value so that the position accuracy can be improved. (c) Provide more measurements to detect the abnormal system and improve the receiver stability. (d) Improve the receiver anti‐jam and spoof resistance performance. Although there are many multi‐constellation receiver solutions at present, most receivers still keep each channel signal track process independently and recent researches on the baseband signal processing of GNSS receiver are mainly focused on the single‐constellation receiver system [4–7], so the nature correlations between the signals of all channels and receiver's dynamic characteristics have been ignored.
