对高层建筑位移的连续评估可以验证其是否满足项目中计算的结构假设，并为结构工程师提供额外的有用反馈。在施工阶段或建筑物使用后出现的意外结构反应可以帮助检测当前和未来的问题，并节省成本。此外，它有助于改进自然现象的风险管理，并可用于验证结构的稳定性，为建筑物提供额外的安全层。全球导航卫星系统（GNSS）技术的技术进步使得高斯方法论在实时控制建筑结构的动态方面取得了重大进步，特别是基于高斯的计算、控制和解释卫星测量测量 实时监测系统的工作原理是在要监测的结构上实施采用 GNSS 技术的局部大地测量网络。然后应用算法来改进补偿网络解决方案，并将其集成到原始软件中。该系统使我们能够实时实现高水平的安全和有效的风险管理，因为每个建筑物都设计了独特的数学模型，可以减少 GNSS 位置误差。以 Torre Espacio 为例，整体数学调整模型将最大误差降低了 40%。该系统已安装在西班牙马德里的一栋高层建筑 Torre Espacio 上，并全面投入运行。
Continuous assessment of the displacement of a high-rise building enables verification that it meets the structural assumptions calculated in the project, and provides additional useful feedback for structural engineers. Unexpected structural responses during the phases of construction, or once the building is in use, can help detect current and future problems, as well as provide cost savings. Furthermore, it contributes to an improved risk management for natural phenomena and can be used to verify the stability of the structure, providing an additional safety layer for the building.The technological improvement in global navigation satellite system (GNSS) techniques has allowed significant advancements of Gaussian methodologies applied to control the dynamics of building structures in real time, especially for calculating, controlling, and interpreting satellite survey measurements, based on Gaussian analysis and least squares adjustment.The real-time monitoring system works by implementing a local geodetic network with GNSS technology on the structure to be monitored. Algorithms are then applied that improve the compensated network solution, and this is integrated into original software. The system allows us to achieve a high level of safety and effective risk management in real time, as a unique mathematical model that allows GNSS position errors to be reduced is designed for each building. In the case of Torre Espacio, the overall mathematical adjustment model reduces the maximum error by 40%. The system has been installed on a high-rise building, Torre Espacio, in Madrid, Spain, and is fully operational.
