Cell phone signal jammer short distance - cell phone signal meter

IFEN GmbH has launched its new NCS Titan GNSS simulator. The NCS Titan has up to 256 channels (and 1024 multipath channels) and up to 4 RF outputs per chassis, providing flexibility and outstanding performance, according to IFEN. The extra complexity and cost of using multiple signal generators is avoided, improving reliability without compromising on functionality, IFEN said in a news release. The innovative design of the NCS Titan allows users configure channels for any GNSS signals and allocate those channels to any of the RF outputs fitted. This flexibility enables the same simulator hardware to be used for an extensive range of tests, for all types of GNSS applications. The NCS Titan GNSS simulator by IFEN. The NCS Titan sets new standards in the field of GNSS Simulation, in terms of fidelity, accuracy, dynamics, iteration rates and reliability, the company said. “The launch of our brand new NCS Titan GNSS Simulator represents another milestone for our NCS GNSS simulator products,” explained Günter Heinrichs, head of customer applications. “This shows clearly once again our commitment to ongoing product enhancement and dedication to providing our customers with best GNSS test equipment on the market.” The NCS TITAN GNSS Simulator has been developed in cooperation with WORK Microwave GmbH, Germany.
