Product Name: Acoustic General Purpose Modem
Manufacturer Name: L3Harris Technologies
Product Description: The L3Harris Acoustic General Purpose Modem (GPM 300) is a cutting-edge subsea communications system designed for long-range, reliable data and voice transmission in challenging underwater environments. This compact and power-efficient modem excels in harsh conditions characterized by multipath, reverberation, and noise where other systems may fail. Proven in high-stakes applications, the GPM 300 is integral to Triton’s Hadal Exploration System, which made history during the ‘Five Deeps Expedition’ by reaching the deepest points of all five oceans, including a record dive of 10,927 meters in the Mariana Trench. Utilizing advanced third-generation MASQ technology and Direct Sequence Spread Spectrum (DSSS), the GPM 300 ensures high reliability and robust communication, effectively mitigating multipath interference. Its capabilities include continuous channel equalization and support for communication between fast-moving platforms with a doppler tolerance of +/-15 knots. The network-enabled GPM 300 is also compatible with L3Harris ELAC UT 3000 underwater systems, making it an essential tool for underwater monitoring and remote command and control applications.
