Relative navigation and control of a hexacopter
2012 IEEE International Conference on Robotics and Automation, 2012 This paper discusses the progress made on developing a multi-rotor helicopter equipped with a vision-based ability to navigate through an a priori unknown, GPS-denied environment. We highlight the backbone of our system, the relative estimation and control.

A survey on terrain based navigation for AUVs [PDF]
, 2010 Terrain Based Navigation (TBN) is a method rootedto the early cruise missile navigation systems, when GPS wasnot yet available. For decades, TBN has been applied as acomplementary system to INS navigation for Unmanned AerialVehicles (UAV).

Control of rodent and human spatial navigation by room and apparatus cues [PDF]
, 2009 A growing body of literature indicates that rats prefer to navigate in the direction of a goal in the environment (directional responding) rather than to the precise location of the goal (place navigation).
