2021/04/12 The Institute of Navigation (ION) celebrated its 75th anniversary on June 25. On June 25, 1945, ION held its first organizational meeting on the Los Angeles Campus of the University of California. According to ION, 55 people attended this meeting, where a “temporary” organization was established until a general meeting could take place in the fall when articles of incorporation could be drafted and adopted, council members elected and the vision for ION could begin to take shape. The global impact of ION has been documented in its more than 2,600 technical papers that have been published in Navigation, the Journal of the Institute of Navigation. Navigation was first published in March 1946. The Institute of Navigation is a non-profit professional organization advancing the art and science of positioning, navigation and timing.

shows 0-28v variable voltage and 6-8a current,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,868 – 870 mhz each per devicedimensions,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,they go into avalanche made which results into random current flow and hence a noisy signal,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,computer rooms or any other government and military office,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.automatic changeover switch.
