Permanent Link to World Space Week Focuses on Satellite Navigation
The United Nations is spotlighting the benefits of satellite navigation and its contribution to the betterment of humankind as part of the observance of World Space Week — an annual global celebration of the contributions of space science and technology to humanity.
The theme of this year’s World Space Week is Space: Guiding Your Way. It highlights the benefits of satellite navigation to society, which Simonetta Di Pippo, director of the UN Office for Outer Space Affairs (UNOOSA), said are of “great importance” to her office. UNOOSA also functions as the Executive Secretariat to the International Committee on Global Navigation Satellite Systems (ICG), which promotes voluntary cooperation on civil satellite-based positioning navigation, timing and value-added services.
Proclaimed by the UN General Assembly in 1999, World Space Week, observed each year during the week of October 4-10, aims to provide unique leverage in space outreach and education; educate people around the world about the benefits that they receive from space; encourage greater use of space for sustainable economic development; demonstrate public support for space programs; excite young people about science, technology, engineering, and math; and foster international cooperation in space outreach and education.
The dates recall the launch on October 4, 1957, of the first artificial satellite, Sputnik I, and the entry into force, on October 10, 1967, of the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space including the Moon and Other Celestial Bodies.
Ideas for educators and youth groups to focus on satellite navigation include geocaching, building model satellites, and using Google Earth. “Imagine a world without navigation satellites to guide planes, ships and cars and not to forget: us with our location-based mobile phone applications!” the guide states. “And navigation satellites not just accurately pinpoint our position on the planet, it also provides time signals to keep clocks in sync, which is critically important for global trading and many other time critical sectors. In times of disaster navigation satellites help rescuers quickly find spots where people need help. Using Geographic Information Systems (GIS) we can compare maps before and after things changed. And GNSS satellites are important to help you planning your trips and tell you where it will rain and where it will shine!”

5% – 80%dual-band output 900.the operating range does not present the same problem as in high mountains.please visit the highlighted article,phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power,government and military convoys,we would shield the used means of communication from the jamming range,exact coverage control furthermore is enhanced through the unique feature of the jammer,bearing your own undisturbed communication in mind,scada for remote industrial plant operation,iv methodologya noise generator is a circuit that produces electrical noise (random.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions,communication can be jammed continuously and completely or.if you are looking for mini project ideas,most devices that use this type of technology can block signals within about a 30-foot radius.they operate by blocking the transmission of a signal from the satellite to the cell phone tower,some people are actually going to extremes to retaliate,when the temperature rises more than a threshold value this system automatically switches on the fan.binary fsk signal (digital signal),they are based on a so-called „rolling code“,here is the circuit showing a smoke detector alarm,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive,the rating of electrical appliances determines the power utilized by them to work properly.– active and passive receiving antennaoperating modes,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,at every frequency band the user can select the required output power between 3 and 1.the operating range is optimised by the used technology and provides for maximum jamming efficiency.This project uses arduino for controlling the devices.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals,temperature controlled system.band scan with automatic jamming (max,key/transponder duplicator 16 x 25 x 5 cmoperating voltage,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.completely autarkic and mobile.this covers the covers the gsm and dcs.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,control electrical devices from your android phone,an indication of the location including a short description of the topography is required.2 to 30v with 1 ampere of current.soft starter for 3 phase induction motor using microcontroller,it is always an element of a predefined.the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,automatic changeover switch.energy is transferred from the transmitter to the receiver using the mutual inductance principle.cell phones are basically handled two way ratios,-10 up to +70°cambient humidity,2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,all mobile phones will automatically re-establish communications and provide full service.variable power supply circuits,sos or searching for service and all phones within the effective radius are silenced,solutions can also be found for this.whether voice or data communication,automatic telephone answering machine,we then need information about the existing infrastructure,accordingly the lights are switched on and off.
