Jingnan Liu, Kefu Gao, Wenfei Guo, Jingsong Cui, Chi Guo
AbstractCommunication, positioning, navigation, and decision-making abilities have evolved into Positioning, Navigation, and Timing (PNT) intelligence during the long process of human migration and hence promoted human evolution. This article defines intelligence and smartness from the perspective of biological intelligence. New requirements as a result of the deve...... hiện toàn bộ
GIL: a tightly coupled GNSS PPP/INS/LiDAR method for precise vehicle navigation Tập 2 Số 1 - 2021
Xingxing Li, Huidan Wang, Shengyu Li, Shuo Feng, Xuanbin Wang, Jianchi Liao
AbstractAccurate positioning and navigation play a vital role in vehicle-related applications, such as autonomous driving and precision agriculture. With the rapid development of Global Navigation Satellite Systems (GNSS), Precise Point Positioning (PPP) technique, as a global positioning solution, has been widely applied due to its convenient operation. Neverthele...... hiện toàn bộ
A review of real-time multi-GNSS precise orbit determination based on the filter method Tập 3 Số 1 - 2022
Yidong Lou, Xiaolei Dai, Xiaopeng Gong, Chenglong Li, Yun Qing, Yang Liu, Yunfeng Peng, Shengfeng Gu
AbstractStable and reliable high-precision satellite orbit products are the prerequisites for the positioning services with high performance. In general, the positioning accuracy depends strongly on the quality of satellite orbit and clock products, especially for absolute positioning modes, such as Precise Point Positioning (PPP). With the development of real-time...... hiện toàn bộ
Estimation method of SBAS dual-frequency range error integrity parameter - 2020
Bo Shao, Qun Ding, Xianbing Wu
AbstractThe development of a dual-frequency multi-constellation satellite-based augmentation system (DFMC SBAS) is in progress worldwide. The broadcasted dual-frequency range error (DFRE) integrity parameter reflects the effects of satellite ephemeris and clock corrections. A user uses the DFRE to calculate the protection level and then determines whether the DFMC ...... hiện toàn bộ
Refining the ERA5-based global model for vertical adjustment of zenith tropospheric delay Tập 3 Số 1
Ge Zhu, Liangke Huang, Yunzhen Yang, Junyu Li, Lv Zhou, Lilong Liu
AbstractTropospheric delay is an important factor affecting high precision Global Navigation Satellite System (GNSS) positioning and also the basic data for GNSS atmospheric research. However, the existing tropospheric delay models have some problems, such as only a single function used for the entire atmosphere. In this paper, an ERA5-based (the fifth generation o...... hiện toàn bộ
Models and performance of SBAS and PPP of BDS Tập 3 Số 1 - 2022
Junping Chen, Yize Zhang, Chao Yu, Ahao Wang, Ziyuan Song, Ji Zhou
AbstractSatellite Based Augmentation System (SBAS) is one of the services provided by the BeiDou Navigation Satellite System (BDS). It broadcasts four types of differential corrections to improve user application performance. These corrections include the State Space Representation (SSR) based satellite orbit/clock corrections and ionospheric grid corrections, and ...... hiện toàn bộ
