National Instruments offers the NI GPS Toolkit for LabVIEW, an extension of the graphical system design environment that expands the NI RF PXI platform to include multi-satellite GPS signal simulation. Using NI 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.

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