Contemporary navigation systems heavily rely on the satellite based systems, mostly still on GPS. The systems proved robust and accurate enough for the vast majority of its today uses. However, there are situations where the reliability and the accuracy of such systems do not meet the expected criteria…

Massive point cloud acquisition is an effective approach for 3D modeling of unknown objects in an indoor environment.

Introduction contains sections of status about the GNSS satellites, back ground of GNSS–based positioning methods, Threats in positioning and description of faults.

Indoor positioning is highly desired for many applications, including personnel tracking for safety in normally unmanned locations. There are several methods and technologies available to…
