Dynamic GNSS Testing and Applications
2009 Reno, Nevada, June 21 - June 24, 2009, 2009Satellite-based global navigation systems are a ubiquitous component in modern guidance systems. Automated guidance in agricultural vehicles is a prime example of how Global Navigation Satellite System (GNSS) receivers can be applied to operations requiring a level or precision, or consistency, which may otherwise be unobtainable.

GNSS quality in pedestrian applications - a eveloper perspective
2008 5th Workshop on Positioning, Navigation and Communication, 2008Localization is a vital part of mobile applications. However, the quality of predominant GNSS-based localization remains inadequate for high-precision scenarios for mobile users. Based on previous work, we discuss the relevance of GNSS for mobile applications focusing in particular on mobile pedestrians.

Design of a Compact GNSS Antenna for Vehicular Applications
2018 IEEE International Conference on Electro/Information Technology (EIT), 2018Two crossed dipole antennas are investigated for GNSS operation on vehicles. The first antenna is a wide band crossed dipole antenna designed by using two orthogonal dipoles with 90° phase shift between them to produce circular polarization. The arms of each dipole are etched on opposite sides of Rogers RO4350 substrate with common square feed.

GNSS Reflectometry and Applications
2017© Springer International Publishing AG 2018. When positioning with GNSS, multipath signal is a reflected GNSS signal that is a nuisance and as such needs to be eliminated. Whereas this reflected signal on the one hand is a nuisance for positioning, for environmental monitoring purposes, it could be useful in monitoring sea-wind retrieval, seawater ...

Interference awareness and characterization for GNSS maritime applications
2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018An international maritime measurement campaign was done to detect and record radio frequency interferences in the Satellite Navigation frequency bands. The system, installed on a large container ship, consists of a conformal seven elements antenna array, an ad-hoc data recorder system and a multi-antenna navigation receiver prototype.
