POSITIONING

Precise GNSS positioning for mass-market applications
Professor Yang Gao
This paper describes some latest work trying to address the abovementioned challenges, including cost and complexity of current correction services, precise positioning with low-cost GNSS sensors,and quick availability of precise positioning solutions in challenging environments. Numerical results are provided to demonstrate their potential to support mass-market applications....

NAVIGATION
Egocentric leisure boat navigation in a smartphone based Augmented Reality application
Thomas Porathe and Jonas Ekskog
In this study, we tested a smartphone based safety app for leisure mariners. The app worked in two modes: "the turned off" phone would give an alarm in the navigator’s pocket 30 seconds before the boat "grounded" (entered into dangerous waters)...

UAV
Automatic detection of dead tree from UAV imagery
Seungmin Lee
In this study, we propose a combination of RF and vegetation index for automatic detection of a dead tree under limited RGB sensor condition. The UAV tree survey has an advantage of observing a large area at one time compared with the visual field survey...
