Latest Patents

Dixon's latest patents include a Global Navigation Satellite System (GNSS) hostile environment simulation. This innovative simulator allows for accurate real-time processor and hardware-in-the-loop (PHIL) simulations of multiple antenna GNSSR/AJ system models. It effectively models antenna effects over the entire signal bandwidth, enabling direct injection of the RF into the GNSSR. The computational efficiency of this system is achieved by applying antenna patterns in the frequency domain. To maintain the integrity of the antenna signals, the transmitter signals are generated over an extended period, which helps to push any residual ringing outside the update window. Efficiency is further enhanced by utilizing a combination of single-precision and double-precision floating-point units to generate the samples of the transmitter signals with single-precision floating-point. All subsequent calculations are then computed in single-precision.

Another significant patent is the Temporal CW Nuller, designed to remove or minimize narrowband interference and jamming power from a GPS receiver's input. This system includes a first signal path with a first input and output, at least one time delay device, and an adjustable phase shift device. The design allows for the introduction of a time delay between signals, enhancing the receiver's ability to filter out unwanted interference.
