CAST Navigation’s GNSS simulation systems provide consistent and repeatable signals and advanced vehicle trajectory modelling, with the ability to simultaneously provide up to four different constellations on each antenna element. The systems can be used in the field or in a laboratory environment and are ideal for testing military navigation and positioning devices.
A powerful performance evaluation module allows users to compare raw measurements and filtered data received from the system under test with vehicle truth data. This provides post-test receiver analysis and truth report generation capabilities that can be archived for future reference.
Trajectories can be defined by user-defined profiles with a wide variety of options for vehicle types and constellation parameters, or generated from previously-recorded external data. A wide variety of other parameters can also be tailored to suit your specific simulation requirements, including multipath, atmospheric delays, spoofing, interference, antenna gain patterns, and more.
