National Instruments has announced a GPS toolkit for LabVIEW which expands the RF PXI platform to include multi-satellite GPS signal simulation.

Using LabVIEW software to create waveforms that simulate up to 12 satellites (C/A codes in the L1 band), engineers can test receiver characteristics such as sensitivity, time to first fix (TTFF) and position accuracy with the NI PXIe-5672 RF vector signal generator.

Engineers can also use a combination of simulated and recorded GPS waveforms as a comprehensive approach for receiver design validation and verification. By recording live GPS signals off the air with a PXI-5661 RF vector signal analyser and a PXI-5690 pre-amplifier (low-noise amplifier), engineers can capture GPS signals with natural impairments that a receiver would observe in the real world.
