The atmospheric excess path delay is a major contributor to the error budget of space
geodetic positioning applications and should therefore be reduced to the maximum possible …

The GNSS precise point positioning (PPP) technique requires high quality product (orbits
and clocks) application, since their error directly affects the quality of positioning. For real …

Precise satellite orbits and clock information for global navigation satellite systems (GNSS)
allow zero-difference position solutions, also known as precise point positioning (PPP) to be …

Surface waves generated by the 2011 Mw 9.0 Tohoku, Japan earthquake were recorded by
both the high‐rate GPS and broadband seismic stations in Taiwan. In this study, we …

Space geodetic applications require to model troposphere delays as good as possible in
order to achieve highly accurate positioning estimates. However, these models are not …

We have been developing a state-of-art tool to estimate the atmospheric path delays by ray-
tracing through meso-scale analysis (MANAL data) data, which is operationally used for …

Dalam bidang survai dan pemetaan, untuk melakukan akuisisi data yang memiliki ketelitian
tinggi harus menggunakan GPS dengan menggunakan biaya peralatan yang relatif besar …

Multi-GNSS networks, for example M-GEX and iGMAS, are set up and grow quickly with the
development of new navigation systems and multi-GNSS receivers. It is unavoidable that …

The ray tracing tools, which we have named'KAshima RAytracing Tools (KARAT)', are
capable of calculating total slant delays and ray-bending angles considering real …
