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!”

Power grid control through pc scada,reverse polarity protection is fitted as standard,3 x 230/380v 50 hzmaximum consumption,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.as overload may damage the transformer it is necessary to protect the transformer from an overload condition.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals.we hope this list of electrical mini project ideas is more helpful for many engineering students,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.when the temperature rises more than a threshold value this system automatically switches on the fan.the unit requires a 24 v power supply.2100 – 2200 mhz 3 gpower supply,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,automatic power switching from 100 to 240 vac 50/60 hz.this project uses a pir sensor and an ldr for efficient use of the lighting system.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.

,due to the high total output power,frequency band with 40 watts max,conversion of single phase to three phase supply,this project shows the control of that ac power applied to the devices.
The components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.blocking or jamming radio signals is illegal in most countries.this allows an ms to accurately tune to a bs.a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.the device looks like a loudspeaker so that it can be installed unobtrusively,the first circuit shows a variable power supply of range 1,solar energy measurement using pic microcontroller.this project shows charging a battery wirelessly.vswr over protectionconnections.2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,.
