The P-SUB-45 is the critical communication link for modern underwater operations. This advanced 0.45-meter tri-band (Ku, Ka, X-band) satellite terminal is engineered to provide secure, long-range data links for submarines and Autonomous Underwater Vehicles (AUVs), ensuring they remain integrated into the global command network.
Designed for the most demanding environments, the terminal is built to military standards to withstand extreme pressure and corrosive conditions. Its robust architecture ensures maximum reliability with minimal maintenance. The core of the system is an advanced two-axis stabilized antenna, which actively compensates for vessel motion to maintain a flawless, continuous connection to the satellite.
Key operational features include flexible band selection, an automatic pointing system that functions with or without GPS, and easy integration with various modems and encryption devices for top-tier security. Controlled via an intuitive web interface, the P-SUB-45 delivers the real-time, trustful communications required for mission success, transforming subsurface platforms into fully networked assets.
