GPS software simulation toolkit
22 July 2009
Design Automation
National Instruments has developed 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 with a cost-efficient, high-performance solution for GPS receiver testing.
The latest version of the toolkit gives engineers new satellite simulation features including extended time duration of non-repeating GPS satellite signals and the ability to customise motion profiles for mobile receiver tests.
Version 1.5 of the toolkit offers an easy-to-use graphical API for validating and testing GPS receivers. Using the toolkit, engineers 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.
The latest version of the toolkit also adds new capabilities for generating custom motion trajectories, so engineers can simulate the signals that GPS receivers capture on specific routes. The ability to simulate these signals using software-defined instrumentation helps engineers conduct customised and repeatable tests featuring route-specific signals without performing expensive drive tests. Additionally, engineers can adjust individual satellite signal powers during signal generation for dynamic range and scenario-specific tests.
