摘要

伽利略是欧洲的全球导航卫星系统(GNSS),它为许多欧洲服务和用户提供了改进的定位和授时数据。伽利略使用户能够比其他可用的系统更精确地知道他们的确切位置。由于性能和精度的提高,在障碍物和无障碍物的环境中访问伽利略信号为工作提供了好处和机会。使用具有伽利略功能的接收器大大增加了观测卫星的数量。与单星座接收机的性能相比,这大大减少了获得厘米级精度位置所需的时间。结果表明,当前伽利略星座适合高精度RTK应用,并且在阻塞和非阻塞环境中提高了可用性、准确性、可靠性和修复时间。比较了RTK GPS和RTK GPS/Galileo在同一天不同时间使用两个参考点获得的结果。研究结果表明,RTK GPS系统与伽利略系统相结合有利于测量应用(厘米精度)。研究表明,在需要厘米精度的测量应用中,RTK GPS/Galileo方法可以替代其他测量方法(全站仪)。

Evaluating Repeatability of RTK (GPS and Galileo/GPS) performance in the analysis of points located in areas with and without obstructions
Abstract Galileo is Europe’s Global Navigation Satellite System (GNSS), which provides improved positioning and timing data with significant benefits for many European services and users. Galileo enables users to know their exact location with greater precision than other available systems. Access to the Galileo signal in the obstructed and unobstructed environment provides benefits and opportunities for work, thanks to the improved performance and accuracy. The use of a Galileo-enabled receiver increases the number of satellites in view significantly. When compared to the performance of single-constellation receivers, this significantly reduces the time required to obtain a position with centimetre-level accuracy. The results indicate the current Galileo constellation’s suitability for high-precision RTK applications, as well as improved availability, accuracy, reliability, and time-to-fix in the obstructed and unobstructed environments. The results of RTK GPS and RTK GPS/Galileo obtained at different times of the same day by using two reference points were compared. The results of this study illustrate that integrating RTK GPS system with Galileo is favorable for surveying applications (cm accuracy). This study shows that in surveying applications requiring centimetre accuracy, the RTK GPS/Galileo method can replace other survey methods (Total Station).
