GLONASS FDMA data for RTK positioning: a five-system analysis

Brack, Andreas

; Männel, Benjamin; Schuh, Harald

(GPS Solutions, 2020-10-24)

The use of the GLONASS legacy signals for real-time kinematic positioning is considered. Due to the FDMA multiplexing scheme, the conventional CDMA observation model has to be modified to restore the integer estimability ...

GLONASS Observation of Artificial Field‐Aligned Plasma Irregularities Near Magnetic Zenith During EISCAT HF Experiment

Sato, H.

; Rietveld, M. T.

; Jakowski, N.

(Geophysical Research Letters, 2021-02-22)

We report on simultaneous observation of artificial plasma density irregularities near the magnetic zenith (MZ) by incoherent scatter radar and GNSS satellite in the high latitude. During an EISCAT (European Incoherent ...

GNSS code and carrier phase observations of a Huawei P30 smartphone: quality assessment and centimeter-accurate positioning

Wanninger, Lambert

; Heßelbarth, Anja

(GPS Solutions, 2020-04-02)

In 2016, an application programming interface was added to the Android operating systems, which enables the access of GNSS raw observations. Since then, an in-depth evaluation of the performance of smartphone GNSS chips ...

GNSS mobile road dam surveying for TanDEM-X correction to improve the database for floodwater modeling in northern Namibia

Arendt, Robert

; Faulstich, Leona; Jüpner, Robert; Assmann, André; Lengricht, Joachim; Kavishe, Frank; Schulte, Achim (Environmental Earth Sciences, 2020-06-28)

The aim of this study is the improvement of the TanDEM-X elevation model for future floodwater modeling by implementing surveyed road dams and the use of filter algorithms. Modern satellite systems like TanDEM-X deliver ...

Gold Ore Treatment at Tetrem Small Scale Mine

Peters, Winfried Dipl. Ing. (2013-09-02)

This publication is the continuation of a previous presentation of the operation and cost analysis of the partly mechanised Tetrem small scale gold mine which discussed in detail the mining, safety and environmental aspects ...

Gold Trade and Gold Mining in the 15th to 18th Century at the Gold Coast (Ghana) and the Activities of the Brandenburg-Prussians

Peters, Winfried Dipl. Ing. (Zeitschrift der Foerderer des Bergbaus und des Huettenwesens1986-05)

Since 1980 the Institute of Mining and Geosciences of the Technical University of Berlin carried out an educational project at the University of Science and Technology (UST) in Kumasi and the UST School of Mines in Tarkwa, ...
