Abstract: A GNSS receiver design is tested, which design includes software for generating position/time related data (DPT) based on raw digital data (dRAW) when the software is executed in a processing unit of the receiver. GNSS signals (SRF) are received via a radio frequency input device while moving the radio frequency input device along a route trajectory. The received GNSS signals (SRF) are fed to a radio-frequency front end of a Representative example of a receiver unit built according to the design to be tested. The radio-frequency front end produces raw digital data (dRAW) representing the received GNSS signals (SRF), and the raw digital data (dRAW) are stored in a primary data storage as a source file (Fsc). The source file (Fsc) is read from the primary data storage, and the source file (Fsc) is processed by means of the software to generate at least one set of position/time related data (DPT).

Abstract: A proposed data processing device includes at least two processor units, which each is adapted to process digitized precorrelation navigation satellite signal data as well as to process alternative data and/or signals relating to at least one function being uncorrelated with the satellite signal data. The device includes at least one data buffer adapted to store data sets, where each set includes a number of instances of the satellite signal data. A control module in the device controls execution of a processing job with respect to a stored data set by allocating individual processing tasks to at least one of the at least two processor units based on a current processing load on each processor unit.

Abstract: A GNSS receiver including a processing unit adapted to process radio signals transmitted from an active set of signal sources and based thereon produce position/time related data. The signals of the active set are processed in parallel with respect to a real-time signal data rate of the signals by a respective tracking channel resource allocated for each signal source. The processing unit also has a monitoring channel resource adapted to process radio signals transmitted from each of at least two signal sources in an additional set of signal sources different from the signal sources in the active set. The processing unit is adapted to process the radio signals of the additional set according to a cyclic processing sequence such that the signals from any of the signal sources in the additional set can be included into a navigation solution without delay.

Abstract: The programmable graphics processor processing a signal from a global navigation satellite system (“GNSS”); has a rasterizer unit, a pixel shader unit and a memory unit. GNSS satellite, received signal converted into a digitized form of the received signal, and transformed by a programmable graphics processor, wherein an array of a corresponding data of the digitized form signal is stored in the memory unit and operated by the pixel shader unit forming a resulting array, written into the memory unit at the first address (see FIG. 3). A first address and values of the endpoints of the array of the corresponding data of the digitized form signal are supplied to the rasterizer unit. The rasterizer unit interpolates values between values of endpoints of the array. The values of the endpoints and the interpolated values of the array correspond to addresses in the memory unit for the array of the corresponding data of the digitized form signal.
