海量点云数据轮廓特征线的快速生成算法_程效军

这本书延伸科学畅销书“全球定位系统 - 理论与实践”，以涵盖全球导航卫星系统（GNSS），包括俄罗斯GLONASS，欧洲伽利略系统，以及其他系统。书是指在一般意义到GNSS来描述各种现有参考系统的坐标和时间，卫星轨道，卫星信号，可观察，数学模型的定位，数据处理，和数据转换。本书是一本大学级入门教材，目的是作为学生的参考以及为专业人士和科学家在大地测量领域，测量工程，导航和相关学科。(This book extends the scientific bestseller GPS- Theory and Practice to cover Global Navigation Satellite Systems (GNSS) and includes the Russian GLONASS, the European system Galileo, and additional systems. The book refers to GNSS in the generic sense to describe the various existing reference systems for coordinates and time, the satellite orbits, the satellite signals, observables, mathematical models for positioning, data processing, and data transformation. This book is a university-level introductory textbook and is intended to serve as a reference for students as well as for professionals and scientists in the fields of geodesy, surveying engineering, navigation, and related disciplines.)
