Operator-software impact in local tie networks

Autor: Michael Lösler, Cornelia Eschelbach, Swetlana Mähler, Joffray Guillory, Daniel Truong, Jean-Pierre Wallerand

Publikováno v: Applied Geomatics. 15:77-95

The operator-software impact describes the differences between results introduced by different operators using identical software packages but applying different analysis strategies to the same data. This contribution studies the operator-software im

Datum Problem Handling in Local Tie Surveys at Wettzell and Metsähovi

Autor: Ulla Kallio, Thomas Klügel, Simo Marila, Swetlana Mähler, Markku Poutanen, Timo Saari, Torben Schüler, Heli Suurmäki

The datum problem is a fundamental issue in the network adjustment when connecting a local measurement network to an external reference frame. Datum elements in 3D networks are scale, translation, and orientation. We consider here the local tie netwo

Operating two SLR systems at the Geodetic Observatory Wettzell: from local survey to space ties

Autor: Torben Schüler, J. Eckl, Horst Müller, Ulrich Schreiber, S. Riepl, Swetlana Mähler, Thomas Klügel

Publikováno v: Journal of Geodesy. 93:2379-2387

The present paper provides an overview on the design of a new Satellite Laser Ranging (SLR) system, the Satellite Observing System Wettzell (SOS-W). It pays special attention on the local survey, the determination and monitoring of the ties between t

Co-location of space geodetic techniques carried out at the Geodetic Observatory Wettzell using a closure in time and a multi-technique reference target

Autor: J. Eckl, Jan Kodet, Karl Ulrich Schreiber, S. Riepl, Torben Schüler, Thomas Klügel, Swetlana Mähler, Christian Plötz

Publikováno v: Journal of Geodesy. 92:1097-1112

The quality of the links between the different space geodetic techniques (VLBI, SLR, GNSS and DORIS) is still one of the major limiting factors for the realization of a unique global terrestrial reference frame that is accurate enough to allow the mo

Differential geodetic stereo SAR with TerraSAR-X by exploiting small multi-directional radar reflectors

Autor: Ulrich Balss, Roland Pail, Thomas Klügel, Michael Eineder, Swetlana Mähler, Christoph Gisinger, Martin Willberg

In this paper, we report on the direct positioning of small multi-directional radar reflectors, so-called octahedrons, with the synthetic aperture radar (SAR) satellite TerraSAR-X. Its highest resolution imaging mode termed staring spotlight enables
