System Features

Produces coherent interference signals for use in single and multi-element systems

Supports up to eight independently controlled jamming elements

Multiple Waveform types can be generated for each element

Jammer signals are transmitted commensurate with the GNSS signals that are assigned for each element

Interference Generators can be stationary or dynamic

Each jammer can be assigned an initial speed, altitude, and stationary or dynamic trajectory

Each interference source’s magnitude and type of modulation is operator selected

Supports operation in both canned and real-time modes of operation

Broadband Noise signals are optimized to deliver Gaussian amplitude distribution with adjustable power output levels

Interference scenarios are 100% repeatable to assure consistent results

Based on CAST proprietary FPGA technology that produces clean waveforms with very low phase noise
