LRAM is GeoSpectrum’s scalable through-water messaging architecture for submerged platforms and remote activation. The manufacturer separates strategic VLF, tactical LF and littoral configurations rather than publishing one range or data rate for all uses. Operator consoles and an uplink station select transmit assets; receivers can interface to existing sonar or dedicated hardware. Public documentation does not establish an underwater multi-hop mesh, open sensor API or cross-vendor protocol compatibility.
