Long-term seafloor geodetic measurements are important for constraining submarine crustal deformation near plate boundaries. Here we present an integrated analysis of a decade of GNSS/acoustic data collected at a site 60 km to the east of northeast T

GNSS Adaptive Beamforming Including Null-steering for Unwanted Signal
Autor: Toshiaki Tsujii, Mutsumi Awai, Sohshi Ohsawa, Takeshi Fujiwara
Publikováno v: JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES. 69:122-127
Unwanted signal such as spoofing, jamming, and multipath is one of the major error factors in GNSS positioning. The purpose of this research is to mitigate the unwanted signal especially multipath error using an array antenna with six elements. We ve

Evaluation of multipath mitigation performance using signal-to-noise ratio (SNR) based signal selection methods
Autor: Valanon Uaratanawong, Chalermchon Satirapod, Toshiaki Tsujii
Publikováno v: Journal of Applied Geodesy. 15:75-85
Satellite signal strength sometimes decreases when multipath exists. This effect reduces signal quality and can lead to a large static positioning error, even the survey-grade receivers are used. Three signal selection methods based on signal-to-nois

Optimization Technique for Pseudorange Multipath Mitigation Using Different Signal Selection Methods
Autor: Toshiaki Tsujii, Valanon Uaratanawong, Chalermchon Satirapod
Publikováno v: Artificial Satellites. 55:77-86
Nowadays, the use of multi-Global Navigation Satellite System (GNSS) has improved positioning accuracy in autonomous driving, navigation and tracking systems utilized by general users. However, signal quality in urban areas is degraded by poor satell

Publikováno v: Frontiers in Earth Science, Vol 9 (2021)
The sustained seafloor geodetic measurement is crucial, even yet sparse in time and space, to constrain the undersea crustal deformation near the plate boundaries. We present an integrated analysis of a decade of GNSS/Acoustic data collected at a sit
