Latest Patents

Barillas' latest patents include a GNSS hostile environment simulator designed for accurate real-time processor and hardware-in-the-loop (PHIL) simulations. This innovative simulator models antenna effects over the entire signal bandwidth, allowing for 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, 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 notable patent focuses on computationally efficient mixed precision floating point waveform generation. This approach leverages high-speed waveform generation 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 adjusts offsets in single precision, ensuring accuracy as the phase grows.
