Simple signal generators can simulate GNSS signals from multiple satellites to determine basic GNSS metrics like time-to-fix and position and time accuracy of simple receivers. However, testing a CRPA system requires real-time baseband GNSS emulation coupled with the ability to present time-synchronized, phase-coherent signals to the device under test (DUT).
In this video, learn more about the solution to this challenge provided by the partnership between Syntony and Keysight. The Syntony Constellator simulates all of the GNSS constellations, propagation models of the ionosphere, troposphere, etc., along with the required attenuation and Doppler shift models coupled with dynamically changing jamming and spoofing scenarios. These baseband signals are then streamed optically into the Keysight VXG microwave vector signal generator for up-conversion to the GNSS carrier frequencies.
