The CAST-110 interference generation system may either be operated in standalone mode or used as a supplement to a CAST simulator.

When used alone, the system provides repeatable support for testing anti-jam performance of GPS receivers. It enables the user to specify jamming levels and signal transmission characteristics for both broadband and narrowband jammers.

When augmenting a CAST simulator with the interference generator option, the user may emulate jamming threats that occur in hostile environments using their simulator inside a chamber or test laboratory.

The system maintains up to eight independently controlled jamming signals - each assigned a unique speed, altitude, and trajectory profile. Modulation types on the interfering signal can be commanded dynamically. Narrowband operating modes include Continuous Wave, Pulsed Continuous Wave, Swept Continuous Wave, FM Noise, Pulsed FM Noise, and Wideband Noise.
