Localization and Target Tracking with Improved GDOP using Mobile Sensor Nodes

open access: yes, 2010
In wireless positioning system, in addition to channel error, the geometric re- lationship between sensor nodes and the target may also affect the positioning accuracy. The effect is called geometric dilution of precision (GDOP).
