On 25-27 of April laboratory of Navigation and GNSS again took part in International exhibition and conference InterExpo Geo-Siberia 2018 in Novosibirsk (Russia). In a frame of the 9th conference “Early warning and crises management in the big data era” PhD candidate at University of Latvia, Riga Technical University & University of Applied Sciences Karlsruhe, Katerina Morozova, has presented the report “QGeoid Computation for Ulaanbaator Region and Parameter Estimation and Optimization Concepts for Integrated Gravity Field Determination with Zenith Camera, Gravity and other Hybrid Data”. As usual the main part of the participation was based on the booth of the laboratory, presenting the last results of the developments in respect to geodetic RaD projects on SatNav&MIT and GNSS/MEMS/MOEMS navigation-platform algorithms, flight control for scalable UAV and manned volocopters, on geodetic infrastructure for GNSS-Services and on geomonitoring.

Three new projects were announced: 1. Flight Control & Automomous Flight for Indoor Navigation (UAV - Daimler Project) 2. Precision GNSS on Smartphones & Tables (Project PREGON-X) 3. Multi-sensor Self-referencing 3D Mapping System for building Information Modeling As a part of the booth the developments on digital Zenith Camera from the partner University of Latvia has been also presented. With the great help of the students of Siberian State University of Geosystems and Technologies and also due to the help with equipment of Department of the Geodesy and Mine Surveying the real demonstration of the online geomonitoring process using GOCA System has been organized.

After a successful testperiod, the R & D project 'Geomonitoring Stuttgarter Fernsehturm' started in 2017 in the con­sortium of the HS Karlsruhe Laboratory for GNSS & Navigation, the engineering geodesy enterprise Messmer, the SWR B.W., the B.W. State Agency for Geoinformation & Landmamagement (LGL) B.W. and the B.W. IT service provider LF.NET. As a combined modeling of integrated 3D network ad­just­ment and finite element models of structural mechanics (FEM) the respectivy RaD deals with the question and forthcoming research topic, whether a monitoring-object is in a 'healthy' or an 'unhealthy‘ physical state. This inter­dis­ciplinary research topic, titled "Structural Health Monitoring (SHM)", aims at an early diagnostics and warning concerning the risk potential of structural objects (high buildings, bridges, towers, etc.) as a tasks in the age of global changes. The mul­tisensor-data is submitted to an integrated server-based modeling, and the resulting time-domain and spectral proper­ties are used to determine changes in the physical state parameters of a geomonitoring object. The geo­monitoring soft­ware processes in real time the internet-communicated multisensor data. A smart­phone app serves both, the remote maintenance of the system, and the presentation of the subject matter to the public and visitors of the Stuttgart TV tower, e.g. based on the visualization of generally com­prehensible state variab­les, such as the amplitude response of the tower oscillating in about 0.2 Hz.

From September to October 2017 the evaluation of new Sokkia iX-1001 and Topcon GT-1001 total stations was done in the HSKA Laboratory on GNSS and Navigation . As a result of the large-scale tests on indoor and outdoor conditions all attributes on quality and accuracy of both stations could be confirmed. The integration of the above new total stations and the online geomonitoring system GOCA was done in that frame and achieved on a 100% functionality. So, both geomonitoring sensors, Sokkia iX-1001 and Topcon GT-1001 ATR, can be used as GOCA-system components for the geomonitoring of any kind of object.

On 8th of February 2018 in a frame of International conference of University of Latvia "Geodinamics & Geospatial research" the laboratory of Navigation & GNSS Technologies has presented two reports with the most actual developments in direction of geomonitoring and navigation tasks. Prof. Dr.-Ing. Reiner Jäger gave a report with topic "Geodetic challenges on positioning & navigation for mobile GIS presented along the NAVKA-Disy project PREGON-X". The second report was presented by master student and GOCA project assistant Dipl-Ing. Lyudmila Gorokhova. The topic of the report is "Model- and Sensor-Integration for an Integrated 3D geomonitoring in a modern data communication structure with applications to the Stuttgart TV tower". The participation in a conference has allowed to organize useful experience exchange and find new possibilities for the further cooperation with international colleagues. The laboratory of Navigation and GNSS Technologies expresses its gratitude to the latvian partners for the invitation to participate in such significant and interesting event!

On 23rd of June 2017 in a frame of study plan a master class of satellite geodesy for students from University was orginized. The laboratory of navigation and GNSS technologies has the whole process of geomonitoring, based on the example of system using u-blox receivers, presented. The students could get the experience in real work with equipment and see the chain of data processing and results analysis.

On 19-21 of April laboratory of Navigation and GNSS Technologies again took place in International Exibition InterExpo Geo-Siberia 2017 in Novosibirsk (Russia). This exhibition was the 13th, where following the tradition the online geomonitoring process based on the GOCA system and other actual projects (NAVKA, DFHBF) were represented. In a frame of COST EFFECTIVE POSITIONING AND GEO DATA SEMINAR, organized by FIG, the Laboratory has presented the new project for geomonitoring of TV tower in Stuttgart.
