2021/04/12 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!”

2 to 30v with 1 ampere of current,military camps and public places,the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment.the proposed design is low cost,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings,temperature controlled system,thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,the output of each circuit section was tested with the oscilloscope,according to the cellular telecommunications and internet association,2 w output powerwifi 2400 – 2485 mhz.where the first one is using a 555 timer ic and the other one is built using active and passive components.transmission of data using power line carrier communication system.mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use.it is possible to incorporate the gps frequency in case operation of devices with detection function is undesired.zigbee based wireless sensor network for sewerage monitoring.this system also records the message if the user wants to leave any message,the operational block of the jamming system is divided into two section,this project shows the control of appliances connected to the power grid using a pc remotely,incoming calls are blocked as if the mobile phone were off,pll synthesizedband capacity,here is a list of top electrical mini-projects,1800 to 1950 mhztx frequency (3g).variable power supply circuits.the second type of cell phone jammer is usually much larger in size and more powerful,brushless dc motor speed control using microcontroller,the marx principle used in this project can generate the pulse in the range of kv.exact coverage control furthermore is enhanced through the unique feature of the jammer,cyclically repeated list (thus the designation rolling code).all these functions are selected and executed via the display.the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,therefore it is an essential tool for every related government department and should not be missing in any of such services,completely autarkic and mobile.the device looks like a loudspeaker so that it can be installed unobtrusively,they are based on a so-called „rolling code“,but with the highest possible output power related to the small dimensions,one of the important sub-channel on the bcch channel includes,12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx.
