“Bei Dou” Shining: Preliminary Exploration on the Development “Dao” of China’s Satellite Navigation Industry

In recent years, China has been able to adopt a state-led national strategy for using BeiDou domestically, while expanding its global reach through a market-driven approach. The development of global navigation satellite systems (GNSS) has become an important part of the "One Belt and One Road" Initiative, and it is an important measure to deepen the strategic partnership between China and the Arab world and to realize the "mutual connectivity and communication" between the two sides. This paper attempts to analyze the structural features of China's frontier technology strategy and its impact on the global influence of China. The authors use BeiDou as a case study to analyze the structural features of China's frontier technology strategy and its impact on its global influence. The paper will show that China has achieved a high-tech innovation strategy for the development of the navigation satellite system (BDS).

Performance Analysis of Positioning Solution Using Low-Cost Single-Frequency U-Blox Receiver Based on Baseline Length Constraint.

With the rapid development of the satellite navigation industry, low-cost and high-precision Global Navigation Satellite System (GNSS) positioning has recently become a research hotspot. The traditional application of GNSS may be further extended thanks to the low cost of measuring instruments, but effective methods are also desperately needed due to the low quality of the data obtained using these instruments. Thus, in this paper, we propose the analysis and evaluation of the ambiguity fixed-rate and positioning accuracy of single-frequency Global Positioning System (GPS) and BeiDou Navigation Satellite System (BDS) data, collected from a low-cost u-blox receiver, based on the Constrained LAMBDA (CLAMBDA) method with a baseline length constraint, instead of the classical LAMBDA method. Three sets of experiments in different observation environments, including two sets of static short-baseline experiments and a set of dynamic vehicle experiments, are adopted in this paper. The experiment results show that, compared to classical LAMBDA method, the CLAMBDA method can significantly improve the success rate of the GNSS ambiguity resolution. When the ambiguity is fixed correctly, the baseline solution accuracy reaches 0.5 and 1 cm in a static scenario, and 1 and 2 cm on a dynamic platform.
