Challenges in Modern Naval Operations

Contested Electromagnetic and Cyber Environments
Naval forces face growing threats from electronic warfare and cyberattacks that can disrupt communications, degrade Intelligence Surveillance Reconnaissance (ISR) capabilities, and delay critical command decisions, putting missions and crews at risk.

Disconnected, Intermittent, and Limited (DIL) Communications
Ships and deployed naval units frequently operate in austere, infrastructure-poor environments where unreliable satellite or line-of-sight communications impede situational awareness and reduce operational tempo.

Fleet-Wide Coordination Across Complex Maritime Environments
Coordinating across diverse vessels, aviation detachments, and forward elements requires secure, high-throughput communications. Platform diversity and aging systems often hinder interoperability and introduce unnecessary complexity.

Solutions Enabled by the ALL.SPACE Hydra 2 Terminal

Multi-Link, Multi-Orbit Connectivity for Resilient Naval Communications
ALL.SPACE’s Hydra 2 is a low-profile, MIL-STD ruggedized, next-generation all-electronic terminal featuring optical digital beamforming and two full-performance Ka-band links operating across commercial and military frequencies, in a single device. It enables concurrent connectivity across GEO, HEO, MEO, and LEO orbits (once fully operational), delivering layered resilience, low- latency ISR, and high-throughput Command and Control (C2), ensuring uninterrupted communications even in degraded environments. Its simultaneous dual-link capability supports make-before-break transitions across MEO and LEO satellite networks with zero packet loss, and concurrent connections to national and coalition networks, ensuring NATO and allied interoperability in mission-critical operations.

Multi-Terminal Operation for Shipboard Redundancy and Coverage
Naval vessels often experience SATCOM blockage due to masts, superstructures, or platform layout. ALL.SPACE will address this with synchronized multi-terminal configurations that use digital beamforming to coordinate apertures. This will maintain consistent connectivity, even boosting throughput when both terminals have satellite visibility, ensuring uninterrupted operations in complex maritime environments.

Alternative Positioning, Navigation, and Timing (Alt-PNT) via Signals of Opportunity (SOOP)
Hydra 2 will leverage simultaneous multi-satellite tracking to extract Time Difference of Arrival (TDOA), Angle of Arrival (AoA), and Doppler data. This will provide resilient navigation capability using Ka-band satellites in GPS-denied or spoofed environments. With rapid beam switching and high satellite diversity, the system will provide reliable positioning to support mission continuity when GNSS is unavailable.

Radio Frequency-over-Fiber (RFOF) for Secure, Scalable Integration
Hydra 2 leverages RF-over-Fiber (RFoF) architecture to transmit RF signals from its topside terminal to below-deck systems with minimal signal loss and high signal integrity. This approach enables centralized encryption, switching, and network integration, while significantly reducing topside clutter, simplifying cabling, and minimizing electromagnetic interference (EMI). Optimized for space-constrained naval platforms, RFoF enhances both system security and scalability without compromising performance.
