National Instruments has released the NI GPS Simulation Toolkit 1.5 for LabVIEW, an extension of the graphical system design environment that expands the NI RF PXI platform to provide engineers a cost-efficient, high-performance solution for GPS receiver testing that exceeds the capabilities of traditional box instruments. The latest version of the GPS Simulation Toolkit gives engineers new satellite simulation features including extended time duration of non-repeating GPS satellite signals and the ability to customize motion profiles for mobile receiver tests. In addition, it offers engineers an easy-to-use graphical API for validating and testing GPS receivers. Using the toolkit, designers can simulate C/A codes for up to 12 satellites in the L1 band. The toolkit also features waveform creation tools to specify both the receiver location and velocity, and the ability to create waveforms with up to 24 hours of non-repeating GPS satellite signals, giving engineers a longer period of non-repeating simulation data than other GPS test solutions. This makes it possible for engineers to achieve extended reliability testing and superior control over signal impairments introduced during design verification testing.
