flexComm Sensor Data Link Modem System
Sensor-to-ship data link communications for protection and monitoring of littoral waters

Spectrum’s Sensor Data Link Modem System (SDLMS) provides a deployable IF-to-Ethernet modem solution for the radio data link between a shipborne transceiver and remote sensors deployed in littoral waters, such as in passive, bottom-fixed, battery-powered hydrophones, unmanned underwater vehicles (UUV), unmanned surface vehicles (USV), and unmanned airborne vehicles (UAV).

The SDLMS consists of two sub-systems: a software defined radio modem transceiver subsystem for the shipborne radio gateway, and one or more remote sensor modem transceiver subsystems for the sensor radios. The default configuration for the shipborne transceiver consists of 8 channels of IF input and output utilizing software reconfigurable processor technology such as field-programmable gate arrays (FPGA), digital signal processors (DSP) and general purpose processors (GPP) to run data link waveforms such as STANAG 7085, Tactical Common Data Link (T-CDL), Wideband Networking Waveform (WNW) and 802.16 (WiMAX).

The remote transceiver subsystem of the SDLMS is packaged in a small 3U CompactPCI form-factor that is conduction-cooled and ready for integration into your remote sensor package. The remote transceiver subsystem features a processor architecture that is virtually identical to the base transceiver architecture consisting of software reconfigurable processor technology combined into an integrated package that is size, weight and power optimized for deployment in harsh environments, and where power is limited.
