Abstract The establishment of the BeiDou global navigation satellite system (BDS-3) has been completed, and current constellation can independently provide positioning service globally. BDS-3 satellites quad-frequency signals, which benefit ambiguity resolution (AR) high-precision positioning. This paper discusses benefits observations, including precision gain multi-frequency sophisticated choice extra-wide-lane (EWL) or wide-lane (WL) combinations for instantaneous EWL/WL AR. Additionally,...
The global BeiDou navigation satellite system (BDS-3) has been in operation recently and many related applications have already compatible with BDS-3 satellites. Most still use the empirical stochastic models for combined regional (BDS-2) positioning. However, different design, may not describe observation precisions correlation characteristics of signals well finally degrade positioning performance. Hence, this contribution, variance-covariance component estimation is applied to calculate...
The emerging Internet of Things (IoT) applications, such as intelligent transportation based on vehicular-lane accurate positioning, have a growing demand for precise and reliable positioning with global navigation satellite systems (GNSSs). It is desirable to use GNSS modules in smartphones achieve high-precision positioning. some brands thus far are able track the new L5 signals GPS QZSS, E5a Galileo, B2a BeiDou-3. L5/E5a/B2a higher quality due their signal structure, which provides an...
