Full Description
This open access book presents the high-precision Real-Time Kinematic (RTK) positioning technique of global navigation satellite systems, including its development, principle, implementation, applications and recent innovations. As the highlights of this book, various extensions of the RTK technique are introduced with emphasis on their features to overcome different challenges of different applications. The applications include the positioning with few reference stations available in a large scale of area, the positioning requiring instant convergence, the positioning at sea without normal communication, the high-precision positioning and attitude determination of rigid objects, the positioning with low-cost chip in the canyon environments. The mathematical models of different extended RTK techniques are derived in a unified framework. The characteristics of different RTK extensions are vividly compared with each other based on diagrams. The demonstration application and experimental results of each RTK extension are introduced. In brief, this book provides comprehensive outdoor high-precision positioning solutions for different scientific, engineering and social applications. It is suitable for readers who need or are interested in the high-precision positioning technique.
