L3Harris & Comtech Launch First Multi-Orbit Embedded SATCOM Modem
In modern defense communications, resilient multi-orbit connectivity is critical. L3Harris Technologies and Comtech Telecommunications have introduced the 5650C2/MP, the industry’s first embedded, multi-orbit software-defined SATCOM modem, enabling tactical operators to maintain reliable links across GEO, MEO, and HEO networks within a single integrated system.
🚀 Hardware Integration for Tactical Operations #
The 5650C2/MP represents an evolutionary leap from Comtech’s C2 modem series, specifically optimized for L3Harris tactical SATCOM terminals. Embedding the modem directly within the terminal casing improves SWaP (Size, Weight, and Power) efficiency, reduces setup complexity, and minimizes operator training requirements in high-pressure environments.
Compatible L3Harris Terminals #
- Panther™ II: Lightweight, manpackable VSAT system.
- Hawkeye™ 4 Lite 1.3M: Portable flyaway terminal.
- Hawkeye™ 4 XY 2.6M: High-throughput, larger tactical platform.
Operational Advantage: Integrated hardware eliminates extra cables and external devices, streamlining deployment and maintaining a consistent user interface across terminal models.
🌐 Dual-Certified Network Connectivity: WGS & SES mPower #
The 5650C2/MP bridges military and commercial SATCOM networks, offering multi-orbit connectivity for front-line operators.
Supported Networks:
- Military Orbits (GEO)
- WGS Constellation managed by US Space Force Delta 8
- EBEM & DSSS waveforms for low probability of intercept
- Commercial Orbits (MEO)
- SES mPower DVB-S2X High-Throughput / Low-Latency constellation
Key Constellation Partnerships #
- SES mPower (MEO): First embedded modem certified for the Medium Earth Orbit DVB-S2X mPower network, enabling low-latency, high-bandwidth communications.
- US Space Force Delta 8 (WGS): Under certification to support EBEM and DSSS waveforms, ensuring secure, military-grade communications.
Once fully certified, the 5650C2/MP will be the only embedded modem capable of simultaneous multi-orbit operation across SES mGS (MEO) and WGS (GEO).
🛡️ Software-Defined Resiliency in Contested Environments #
The software-defined architecture of the 5650C2/MP provides dynamic adaptation in electromagnetic warfare environments, offering operators unmatched flexibility and security.
- Anti-Jam & Anti-Intercept: Military-grade DSSS waveforms ensure low probability of intercept (LPI) and low probability of detection (LPD).
- Rapid Reconfiguration: Operators can update waveform profiles on the fly, adapting to evolving mission requirements without replacing hardware.
⚙️ Technical and Tactical Specifications #
