Phased-Array (CRPA) Antenna Simulation & Testing

CAST Navigation CRPA (controlled reception pattern antenna) simulators provide coherent, and repeatable GNSS RF signal wavefronts for phased-array antenna systems used for tactical positioning and navigation. A complete set of signals is generated for each antenna element, with GNSS and interference waveforms generated separately and spatially offset to reflect real-life phase differences in signal reception.

The versatile simulators are fully customizable and can simulate both static and dynamic motion profiles, tailored to a wide range of airborne, orbital, ground-based or marine platforms. They can be configured to deliver a full constellation of GNSS satellites, with up to 16 satellites in view per constellation signal type and composite signal RF output element.

A range of other parameters can also be controlled, including location, jamming and spoofing, atmospheric delays, RF output power levels, multipath, and more.
