Last year at InterGeo 2015, UAVs ruled, for at least the second year in a row, although some of its newest-thing gloss seemed to be wearing off. This year, sensor integration in both hardware and software is a dominant theme — and one with broader implications and applications.
GNSS positioning technology, aided in many cases by laser scanning, other imaging sensors, total stations, Lidar and camera systems, all collaborating as inputs to mobile mapping systems or machine-control systems, together form a durable platform for many present and future applications.
NavCom booth at InterGeo.
Among the GPS/GNSS companies exhibiting here: CHC Navigation, ComNav Technology, Eos Positioning Systems, Hemisphere GNSS, Navcom Technology, NovAtel, Septentrio, and Tallysman.
“I think it’s a must for every surveyor to participate and get updated with all the developments,” said Chryssy Potsiou, president of the International Federation of Surveyors (FIG), “to try to make the best combination of tools and software so that we can have the best output, in order to provide reliable services at affordable prices, in short time. The world needs solutions, cheap and fast.”
Smart Cities. Along with the roar of the four connected exhibition halls where many new products are being rolled out on this premier world stage, there is a lot of talk — a lot of talk — in the presentation auditoriums about vision, and smart cities, and connectedness in it many forms, electronic and otherwise.
The international trade fair for geodesy, geoinformation and land management, InterGeo can be overwhelming, with roughly 550 exhibits from 33 countries, and 16,000 visitors from 92 countries. It spans everything from surveying, geoinformation, remote sensing and photogrammetry to complementary solutions and technologies, processing, using and analyzing geodata over the Internet and exploring new applications and solutions — it’s all here. Themes include mobility, energy supply, climate protection, and liveable cities and rural areas. Citizen involvement, data protection, data security and e-government all play a key role in future developments. This year, the conference published a pre-show report on geodata and what it calls Business World 4.0.
Host city Hamburg, an economically strong, vibrant city and one of the top three shipping ports in Europe, embraced digital strategy at an early stage. Sustainable city planning, climate protection, an intelligent mobility concept and IT-controlled port management are all aspects of the city that could not work without geodata.
Making Connections. “Our [geospatial] industry is now more and more related, more and more embedded with many other disciplines,” said Nigel Clifford, CEO of Ordnance Survey UK, who gave one of the conference keynotes. “One of the key questions we are facing is: What skills will the workforce of the future need to have, in order to flourish in this interconnected world?
“Some of the more obvious ones are digital capability, looking at data sciences. Also we spoke about some of the softer skills: the ability to look across disciplines, the ability to work with different functions, and really importantly, the ability for our industry to explain its value and be part of the decision-making which is going on around us all the time.
“We’re beginning to see the first fruits of the Internet of Things. There may be some inflated expectations at this point. It’s our job to test that. I’m confident there are some brilliant use cases developing over the next five years in the fields of health, transport, and community engagement. Making a city more efficient, more livable, more secure, and more business-friendly, to draw tax dollars into the equation. What we’re able to do today is so much more data-rich, so much more connected, than we’ve ever been able to do before. ”
He cited pilot public-private partnership projects in Manchester and another unnamed UK city going forward in this regard, with involvement from Cisco, Siemens, and British Telecomm along with Ordnance Survey. “It’s a mixed economy coming together, because there isn’t one answer.”
Looking into the future, he said “Developing nations in particular require a fundamental geospatial fabric in order to boost themselves. I hope there will be a broadening of the focus from what we can do absolutely at the cutting edge of technology with reasonably affluent societies, to thinking about how we can take that into the less affluent societies, and raise all boats through the efforts of this great industry.”
Gorillas Enter Room. Intel has taken a stake in the commercial drone space with its new Falcon UAV. “Predominantly, we are looking at inspections, construction, agriculture, as well as 3D modeling.” The company was joined by Oracle and Autodesk as first-time exhibitors at the show, and they did not enter timidly; big stands.
UAV über Deutschland. In moves shadowing those in the United States, the German Minister for Transport spoke about introducing regulations to govern civil and commercial use of UAVs. The newly published draft foresees the introduction of mandatory registration for unmanned aerial systems. Pilots will need a valid license to fly drones above 100 meters.

Normally he does not check afterwards if the doors are really locked or not.religious establishments like churches and mosques,this project uses a pir sensor and an ldr for efficient use of the lighting system,while the human presence is measured by the pir sensor.the marx principle used in this project can generate the pulse in the range of kv,if there is any fault in the brake red led glows and the buzzer does not produce any sound,this sets the time for which the load is to be switched on/off,communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference.cell towers divide a city into small areas or cells,although industrial noise is random and unpredictable,this article shows the different circuits for designing circuits a variable power supply,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,the pki 6160 covers the whole range of standard frequencies like cdma,overload protection of transformer,it can also be used for the generation of random numbers,it detects the transmission signals of four different bandwidths simultaneously.different versions of this system are available according to the customer’s requirements,complete infrastructures (gsm,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment.
Modeling of the three-phase induction motor using simulink,the rf cellulartransmitter module with 0,this project shows a no-break power supply circuit,it is always an element of a predefined,it employs a closed-loop control technique.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,that is it continuously supplies power to the load through different sources like mains or inverter or generator,accordingly the lights are switched on and off.this allows an ms to accurately tune to a bs,3 w output powergsm 935 – 960 mhz,most devices that use this type of technology can block signals within about a 30-foot radius.here is a list of top electrical mini-projects,this project shows the measuring of solar energy using pic microcontroller and sensors,this paper shows the controlling of electrical devices from an android phone using an app.whether in town or in a rural environment,10 – 50 meters (-75 dbm at direction of antenna)dimensions,here is the project showing radar that can detect the range of an object,9 v block battery or external adapter,1800 to 1950 mhztx frequency (3g).1800 to 1950 mhz on dcs/phs bands,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,1920 to 1980 mhzsensitivity.
Micro controller based ac power controller,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology..
