Introduction to the MPT30Ka SATCOM System
Orbit Communication Systems has recently introduced the Multi-Purpose SATCOM Terminal (MPT30Ka), a Satellite Communication solution specifically engineered for tactical vehicles and critical missions. This unveiling occurred at the DSEI UK 2025 exhibition, where Lior Rudminsky, the Vice President of Products and Solutions, elaborated on its advanced features and capabilities.
Technical Specifications
The MPT30Ka features a compact 30 cm dish made from a combination of composite materials, metals, and 3D-printed components. For those seeking greater capacity, the MPT46Ka model boasts a 46 cm dish and operates within the Ka frequency band.
Key Frequencies:
- Transmitter: 29.0 – 31.0 GHz
- Receiver: 19.2 – 21.2 GHz
Enhanced Operational Capabilities
The efficiency of the MPT30Ka system stems from its innovative antenna technology, which provides superior gain while minimizing power consumption. This attribute makes it especially valuable for military applications, where energy efficiency is critical.
Versatility and Compatibility
- Modem Agnostic: Designed for plug-and-play usability.
- Interoperability: Compatible with various military vehicles, maritime assets, and aircraft.
Adaptability in GPS-Denied Environments
A standout feature of the MPT30Ka is its operational capability in environments where GPS is unavailable. This system can effectively track satellites across varying orbits—geostationary, low, medium, and high Earth orbits—while adapting to different networks and frequencies based on interference.
Dynamic Bandwidth Management
The terminal employs dynamic bandwidth allocation, which adjusts based on the specific data types being transmitted, including real-time video and voice communications. At the DSEI event, Rudminsky announced impressive performance metrics:
- Download Speeds: 130 Mbps
- Upload Speeds: 29 Mbps
Advanced Antenna Design
The MPT30Ka is fitted with cutting-edge low-noise block-down converters, contributing to a gain-to-noise-temperature (G/T) measurement of:
- 10.0 dB/°K for the MPT30Ka
- 13.5 dB/°K for the MPT46Ka
These figures indicate a remarkable sensitivity level for the satellite antenna, optimizing its signal-gathering capabilities against system noise. The selected antenna model achieves an efficiency rate of 85%, significantly surpassing the industry standard of approximately 60%.
Effective Isotropic Radiated Power (EIRP)
- MPT30Ka EIRP: 50.0 dBW
- EIRP Spectral Density: Enhanced by minimized antenna side lobes, increasing direction-specific signal power.
This effective transmission not only amplifies signal strength but also reduces bandwidth requirements and operational costs for end-users.
Compliance with Military Standards
The MPT30Ka has undergone rigorous testing to ensure compliance with multiple military standards:
- MIL-STD-188-164C
- MIL-STD-810G
- MIL-STD-1275
- MIL-STD-461G
These validations guarantee that the system remains functional despite electromagnetic and environmental challenges.
Future Enhancements
Looking ahead, Orbit Communication Systems plans to extend the MPT30Ka’s capabilities by enabling simultaneous operation across Ku, Ka, and additional bands, aiming to lower both financial costs and spatial requirements for end-users.
Conclusion
The launch of the MPT30Ka SOTM significantly solidifies Orbit Communication Systems’ position in the mobile SATCOM sector. By enhancing efficiency, resilience, and cost-effectiveness, the MPT30Ka stands ready for real-world deployment across air, land, and maritime platforms. Continuous expansion of its multi-band capabilities will further empower users operating in contested environments, ensuring communication resilience in the modern battlefield.
