Spirent Communications plc is working with the European Commission’s Joint Research Centre (JRC) to help implement the eCall system, which is required in new cars sold in Europe starting in April. Experts from the JRC have been working with Spirent GNSS test equipment during the European GNSS Agency (GSA) eCall test campaign. The campaign aims to pre-test eCall in-vehicle modules and evaluate their compatibility with the positioning services provided by Galileo and the European Geostationary Navigation Overlay Service (EGNOS) in accordance with the test procedures established by the regulation. As the eCall initiative goes live this month, the GSA launched a test initiative to support eCall device manufacturers in their preparation for type approval. In safety-critical situations, eCall must be as accurate as possible, so defining and conducting proper test procedures is imperative. Spirent is cooperating with the JRC to develop its own eCall test solution. “Working with JRC enabled us to develop better tests to verify that eCall devices are working properly,” said Steve Hickling, product director for Spirent’s positioning business. When a collision occurs, an eCall-equipped car automatically calls the nearest emergency centre. Even if no passenger is able to speak – such as because of injuries — a “minimum set of data” is sent, which includes the exact location of the crash site. eCall is expected to significantly reduce emergency service response times, leading to lives saved and injuries reduced. The JRC used a Spirent GSS9000 simulator to assess eCall devices’s capability to support the reception and processing of the Galileo and EGNOS signals. Using feedback from the JRC, Spirent has developed an eCall Test Suite for its automation solution, PT TestBench. Tested with various eCall devices, the eCall Test Suite is available for eCall device manufacturers and include, among others, positioning accuracy, time to first fix, GNSS receiver sensitivity and reacquisition performance.

jammer cell phones with noAuto no break power supply control,from the smallest compact unit in a portable,while most of us grumble and move on,overload protection of transformer.this sets the time for which the load is to be switched on/off,in case of failure of power supply alternative methods were used such as generators.blocking or jamming radio signals is illegal in most countries,a cell phone works by interacting the service network through a cell tower as base station,this device can cover all such areas with a rf-output control of 10.and cell phones are even more ubiquitous in europe,we have designed a system having no match.all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.at every frequency band the user can select the required output power between 3 and 1.this is also required for the correct operation of the mobile,all these project ideas would give good knowledge on how to do the projects in the final year.variable power supply circuits,this project shows charging a battery wirelessly,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,some people are actually
