Time Synchronization of TESLA-enabled GNSS Receivers [PDF]
As TESLA-enabled GNSS for authenticated positioning reaches ubiquity, receivers must use an onboard, GNSS-independent clock and carefully constructed time synchronization algorithms to assert the authenticity afforded. This work provides the necessary checks and synchronization protocols needed in the broadcast-only GNSS context.

Micromachines, 2017 When strong earthquake occurs, global navigation satellite systems (GNSS) measurement errors increase significantly. Combined strategies of GNSS/accelerometer data can estimate better precision in displacement, but are of no help to carrier phase ...

Towards a Semiautonomous Young Spruce Forest Late Cleaning
Journal of Field Robotics, EarlyView.ABSTRACT Cleaning a seedling spruce stand is an important silvicultural task required to help the young spruce trees thrive. It is usually manual work with a clearing saw. Mechanized solutions have been proposed, but they have not worked out well, since the driver has challenges in seeing the seedling trees that should be left growing.

Remote Sensing in Ecology and Conservation, EarlyView.We used fixed‐wing drones and Beyond Visual Line of Sight flying to create high‐resolution imagery and Digital Surface Models (DSMs) of six large king penguin colonies (colony population sizes ranging from 10,671 to 132,577 pairs) in South Georgia. We used a novel DSM‐based method to facilitate automated and semi‐automated counts of each colony to ...

An Experimental Validation of Accurate and Precise GNSS Time Synchronization in Vehicular Networks [PDF]
arXiv, 2020 Vehicular Networks are one of the enabling technologies for cooperative Intelligent Transportation Systems. For accurate and precise time synchronization in vehicular networks, Global Navigation Satellite System (GNSS) is getting increasing attention for effective use of its time dissemination to vehicular networks.

Small, EarlyView.A systematic study of gold‐silver nanostars (GNSs) formation reveals the key role of silver and AgCl in directing GNSs growth. Using a rapid and green synthesis approach, temperature and AgNO₃ addition influence the process. This enables control over GNSs morphology, size, and concentration, allowing their properties to be tuned for various fields such
