Abstract: An electronic device including a device architecture including a tracking engine (TE). The TE includes a plurality of TE channels, each TE channel including a plurality of correlators. In a first mode of the electronic device, the electronic device is configured to: divide the plurality of TE channels into a first group of TE channels and a second group of TE channels; configure the first group of TE channels to search for and detect a plurality of signals in parallel, search for and detect the plurality of signals according to a sequential order, or both; and configure the second group of TE channels to validate and track the detected plurality of signals. In a second mode of the electronic device, the electronic device is configured to configure the first group of TE channels and the second group of TE channels to track the detected plurality of signals.

Abstract: A GNSS hostile environment simulator for accurate real-time processor & hardware in the loop (PHIL) simulations of a multiple antenna GNSSR/AJ system models antenna effects over the entire signal bandwidth allowing direct injection of the RF into the GNSSR. Computational efficiency is achieved by applying the antenna patterns in the frequency domain. To preserve the integrity of the antenna signals, the transmitter signals are generated over an extended period to push any residual ringing outside the update window. Efficiency is further enhanced by using 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.
