GPS Streaming Example for the NI PXIe-5644R


GPS Streaming Example for the NI PXIe-5644R »


This example integrates the NI GPS Simulation Toolkit for LabVIEW with the NI PXIe-5644R Streaming sample project to continuously generate simulated GPS signals.



Description: With more than 800 MB/s of PXI Express bandwidth, the NI PXIe-5644R can sustain continuous generation for signals occupying its full 80 MHz of real-time RF bandwidth. When combined with the real-time CPU-based waveform syntehsis of the NI GPS Simulation Toolkit, this example enables simulation of up to 12 satellites with custom power levels, Doppler shifts, and receiver motion trajectories.

Wonderful example.   I would love to see a cut down version as well.  The GPS Streaming from Binary file would make a nice example by itself and can easilly be modified to stand on its own without the GPS TK Dependancy.
