 So welcome everyone. Today I first want to thank you for coming and attending our presentation. It would be more like a story. We will tell a story you will not go so much details in about the research. So I'm Ahmad El Said and I'm working for TechSplore in Research and Development Department and today I am coming to tell you about the story of TechStand. TechStand is a system that we started as an idea in our company in TechSplore in Germany and developed to be an application now in almost 11 countries all over the world. So expertise will find exciting information in this journey and also nonexpertise will find really a good journey to listen to. So I will start with the motivation for our development. The motivation was that dynamic monitoring is really a big field in the field of geodesy and the current technology was at this time was mainly using geodetic receivers and antennas for the application of these things which is very expensive for clients especially small clients and also even for a big organization needs expertise to analysis this kind of data. So some companies was working on the low cost to reduce the cost of these geodetic receivers and antennas but at this time that was not enough accuracy for a big applications of the geodynamic. So the goal of our development at this time was to develop easy system but still achieve the accuracy of the geodetic or the expensive systems. So this was our goal but also to make it easy to use so no expertise will need to involve it so much in this system but also to be autonomous. So in general in this kind of applications you will need so many devices to work to get good accuracy but our system working autonomously so this was the goal in the beginning to make a really easy system but after all of that to be with reasonable price so not be so expensive like the geodetic devices in the market in this time. After that we did a lot of investigation in this time to investigate the market from the hardware and from the software perspective to build a complete system for this one. The hardware development was mainly about make a surveying for the market see what is the best available receivers and antennas this time and then to move on after achieving the good selection and calibration and configuration of this hardware to do a complete system of software. So the system of the software that started from the binary data so we collected the binary data trying to get it in the readable format which is Rynix in this kind of data and then to make a complete automatic system out of this binary data and Rynix data and do also autonomous validation for this accuracy. So here's the exciting information and slides so this was the evaluation of the market of the low cost in this time. Here we collected the best of the market but also did the analysis using the best available software in this time so this is not our software this is software from Narcan the Canadian PBB analysis service and we as you see here with a reddit dot that it's a lot of rejected signal in this time because of the discontinuity a lot of discontinuity of the receivers and antennas in this figure and this how we reached by the end of the hardware development so here was more about calibration more about configuration of the best receivers and antennas in the market so we converted this image to be this one with this one we was really happy about the quality of the signal that we got we almost get zero percentage rejected of the signal and we also get very high accuracy which is millimeter two or three millimeter in X and horizontal and in vertical about seven millimeter this result really make us so exciting to make more development for the software so not only be like selling a hardware for clients as they cannot use it or they hardly can get this kind of results so we we think deeply how to make also a software to be a complete system to give the client a complete system and make it easy for him to use it so before this step we did a second validation for our hardware that we got a baseline solution with different IGS stations so we solved with our receiver data which is our triple zero the first line on the right we solved with this hardware with 15 IGS stations very long baseline very short baseline from 90 kilometer to 900 kilometers we get in all of that one I don't want to go in so much detail but in general we got in a procession of two three millimeter in horizontal seven millimeter in vertical again something give us more push to develop our own software for this hardware so we started with the hardware with the flow from the at the left we started from the logging of the data converting the data processing the data and also make a complete cloud system for us so we speak here about tech stand as a hardware and the sky text sky as a cloud service a complete as cloud service for text blur which we can collect all the data all the GPS data but also other sensors from for the clients to make it a complete umbrella software so now for the client it's it's really easy and we took all the complication of the database the complication of processing the data as the analysis of the data inside these text sky and give as a client direct access to the daily XYZ of the measurements then we went to the validation validation of the complete system here in this test we made the measurements was our software was our hardware so the measurement was our hardware and the analysis was our software our text text sky software and here we as a test was building by two tech stand one is movable and the other one is fixed and we try to move like one centimeter every day and at the end half centimeter and we as we can see in the map that there is really complete correlation between when I move the antenna one centimeter you can see directly on the other map that completely correlated to the measurement so this is a second validation for our system then we made a second assert validation at the IGS station at GFZ we are located on both stamps so we in correlation with GFZ we did this measurement with the IGS station and one antenna the other antenna was our system and we get also a complete correlation as you see in the graph and at this point we said to the world is that we have really tech stand a complete system that can provide millimeter precision without any interference from experts or anything so the system working completely automatic completely autonomous was one system for GPS for GPS expertise knows that what what does it means that you have one system in install it in the field you get every day XYZ in millimeter precision without any interaction of any expertise so this is a feature of our system it's autonomous it's automatic data processing provide to the client daily XYZ in millimeter accuracy and it's also we made something more more than this one which is sorry so fast so we made this tech stand working also with four antennas so for for the client so it doesn't even have accessibility for so many devices to be built in the field we made for him tech stand which working with four antennas in the same times all this antenna uploaded directly to our tech sky clouds providing for the client final XYZ really processed really accurate precise data then we started also as I introduced in the beginning that we have now tech stand in 11 countries five of them is already measuring in France Netherlands Australia and Germany Turkey and we have other five countries we already agreed with them to install tech stand I will give two examples of our projects that we already did one is movable or dynamic monitoring in a bridge in France and second one will be stable or a fixed position measurement so for example this is as a measurement from a brodo in France which is the hanging bridge and we measured there for 15 months so this is 15 months data and we can see a really correlation between the movement here of the green line is a movement in horizontal direction and also the temperature so for example at 25 degree temperature we have the maximum extension on the bridge so we see really big movement and also in the shrinking we see the minimum movement I don't like to go so in so much details but I just wanted to show you some examples from what we did with the tech stand another project which is a donation project the tech stand text blower give it for after as a minor this is as a minor donation project that we did after the Turkey a catastrophe I will not mention here so much tomorrow we will have a presentation by my colleague Bastiaan Kimmel in the same hole so who is interesting who can come and attend more and listen more about this kind of project in general we I will give just one example from Adana so in this project we have six countries I will give one example from Adana which is in Turkey here we see the movement of the tech stand movement data in blue and the correlation between the movement and the earthquakes happening in this area and we also provide what's called the center point measurement or center point mapping so we collect the data every one month we get the center point of this month and then we provide a complete 2d map to show the directions and the magnitude of the movement on the as you see in the right so we from for example here this measurement for six months from April to September and we see the direction and the movement of the tectonic area in this place so for really expertise like with GPS they know how difficult in the beginning to get this kind of data so we started with really aim to get this dream at the end to give the expertise maybe in a structural geology for example that they don't like to go and so much details of geodesy really a good accessibility for the GPS data you are all invited also to our booth to get account to our textile surface and I thank you I think I finished my time so
