Preliminary Study on Multi-Station GPS RTK Positioning to Support Emergency Service Operations in Indoor Areas

  title={Preliminary Study on Multi-Station GPS RTK Positioning to Support Emergency Service Operations in Indoor Areas},
  author={Liu Binghao and Wang Jian and Meng Xiangchao and Chris Rizos},
An indoor positioning system for emergency operations such as fire fighting based on radionavigation principles needs the coordinates of portable transmitters to be determined rapidly and with high accuracy. Generally GPS real-time kinematic (RTK) positioning requires tracking of 4 or more satellites with good geometric distribution to provide centimetre-level accuracy. In urban canyons, however, high buildings block signals from satellites with low to medium elevation angles hence… Expand

The Use of the L-Curve in the Regularization of Discrete Ill-Posed Problems
A unifying characterization of various regularization methods is given and it is shown that the measurement of “size” is dependent on the particular regularization method chosen, and a new method is proposed for choosing the regularization parameter based on the L-curve. Expand
