Initial Results of RTK/OTF Positioning Using the Ntrip Data Teletransmission Technology
Technical Sciences, 2008 The paper presents the initial results of RTK/OTF satellite measurements made using NTRIP Internet data transmission. Two permanent reference stations belonging to the University of Warmia and Mazury in Olsztyn were used for test measurements. As a result of measurements taken at three measurement points situated 1,5 to 20 kilometers from the reference

Handheld‐Colorimeter‐Based Soil Color Survey of Red Soils in SW Brandenburg, North German Lowlands
European Journal of Soil Science, Volume 77, Issue 4, July/August 2026.ABSTRACT Handheld colorimeters are a relatively novel tool in soil science that allow the objective measurement of soil color, potentially even in situ. Here we set out to assess the measurement reproducibility of two low‐cost colorimeters under simulated field conditions.

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.

Datum: Journal of Geodesy and Geomatics, 2022 Kegiatan pengukuran dan pemetaan bidang tanah dapat dilakukan dengan menggunakan GNSS metode RTK (Real Time Kinematic) baik RTK-Radio maupun RTK-NTRIP. Pada metode RTK-NTRIP terdapat dua jenis yaituRTK- NTRIP Single Base dan Network RTK. Kedua metode tersebut dibedakan berdasarkan jumlah titik ikat CORS yang digunakan sehingga menyebabkan terjadinya ...

The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model
Space Weather, Volume 24, Issue 2, February 2026.Abstract The Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed geomagnetic conditions.
