Latest Patents

Filarsky's latest patents include a GNSS hostile environment simulation, which is designed to provide accurate real-time processor and hardware-in-the-loop (PHIL) simulations. This innovative simulator models antenna effects over the entire signal bandwidth, allowing for the direct injection of 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, effectively pushing any residual ringing outside the update window. Furthermore, efficiency is enhanced through the use of a combination of single-precision and double-precision floating-point units for generating transmitter signal samples.

Another significant patent is the computationally efficient mixed precision floating point waveform generation. This approach leverages the high-speed generation of waveforms using single-precision floating point numbers while minimizing the loss of precision typically associated with pure single-precision floating point. The method computes a reference phase in double precision and then calculates offsets in single precision, ensuring that the double precision reference phase is recomputed as necessary.
