Precision Positioning Technology
The report presents precision positioning methods and technologies suitable for intelligent machines in indoor and outdoor conditions. Precision positioning refers to high-accuracy position determination for localisation, navigation and situational awareness applications. Typically, precision positioning is understood to include location accuracies in the order of sub-meter level.
For intelligent machines, precision positioning is critical for the reliable guidance and control as well the reliable operation of future autonomous machines. This report introduces an overview of the various technologies capable to provide precision positioning for mobile work machines of today and the future. The report gives a thorough oversight of the various technologies and methods, ranging from radio frequency approaches to self-contained sensors and optical methods as well as presantation of observation and localisation algorithms. One part of the report studies hybrid positioning methods.
