Portable Dual Frequency GPS Simulator
Our portable dual frequency GPS satellite simulator, CAST-1000, is much like the CAST-2000. It simulates GPS RF signals to allow repeatable testing in the laboratory or in the field. It also uses dual frequency signal generation technology, which can be controlled in real time or configured prior to the test. The difference is that CAST-1000 is mobile and easy to carry around, making it the high-performance solution to responding quickly to test requirements.
The CAST-1000 can produce GPS signals with up to 12 satellites in view. Chosen from the pre-configured Pseudo Random Noise codes, it simulates signals for satellites of P Code on L1 and L2, and C/A Code on L1.
The dual frequency GPS RF signal generator’s 12 channel configuration provides the same capability as six channel units, but with six additional channels. This allows any combination of visible SVs to be selected.
The GPS/GNSS 1000 system is highly programmable. Operators can choose from a range of vehicle types, and reproduce dynamic motion for all terrestrial, space-based, airborne, and aquatic vehicles. A trajectory can be created through profile configuration, or by utilizing 6-DOF dynamic profile data collected in the field.
This CAST Simulator product also features a performance evaluation module, which allows comparison between raw data and filtered data the GPS navigation system provides. The module shows the true vehicle position for a comprehensive post-test analysis.
