Galaxynav Positioning and Orientation System

The new generation Positioning and Orientation System (POS) that integrates
Inertial Navigation System (INS) and Global Navigation Satellite System (GNSS)
has become the core element of next generation spatial information acquisition
systems or Mobile Mapping Systems (MMS). The requirements of an
un-interpreted and stable navigation system from navigation applications initialize
the development of INS/GNSS integrated navigation and positioning system.
However, the higher positioning and attitude estimation accuracy requirements of
a modern mobile mapping system that integrates digital mapping camera,
LIDAR, and video camera with a geo-referenced platform from geomatics
engineering applications further revolutionize the latest development of those
technologies adopted by INS/GNSS integrated positioning and navigation system.
Figure (1) illustrates the examples of MMS.

     General speaking, the accuracy requirement of mobile mapping system is at
   least ten times higher than that of general navigation applications. In other words,
   geomatics applications dominate the progress of INS/GNSS technologies in
   terms of accuracy requirements.
