The GRX family of software defined multi-channel monitoring receivers are the ideal and most economic solution for modern COMINT systems. Traditional narrowband signal monitoring capabilities such as AF/IF streaming, demodulation and recording, are combined with wideband SDR technologies to drive automated processes such as advanced data decoding and signal analysis functions. With multiple receiver channels in a rugged and compact rack, the GRX receivers are suitable for fixed and mobile applications.
