In SATCOM On-the-Move (SOTM), performance has traditionally come at a cost—both in physical size and operational efficiency. Large, power-hungry satellite terminals have long been accepted as a necessary compromise for maintaining reliable, high-bandwidth connectivity in motion. But for military, aerospace, and other mission-critical mobile applications, that compromise is no longer acceptable.
Today’s operational environments demand compact, lightweight, and power-efficient terminals without sacrificing link quality, data throughput, or robustness. In this post, we’ll explore why compactness has become a mission-critical requirement and how Novocomms’ Metarray™ technology is reshaping the SATCOM landscape.
1. The SWaP-C Imperative in Modern Defence & Aerospace
In military and aerospace engineering, SWaP-C—Size, Weight, Power, and Cost—is more than an acronym. It’s a set of critical design parameters that directly impact operational readiness, logistics, and mission endurance.
- Size: Smaller terminals reduce platform integration challenges, especially on armoured vehicles, UAVs, and rotary aircraft, where every millimetre matters.
- Weight: Lower mass improves fuel efficiency, increases payload capacity, and reduces wear on mechanical systems.
- Power: Reduced consumption extends operational duration for battery-powered platforms and decreases the load on vehicle power systems.
- Cost: Lower hardware complexity and easier deployment reduce overall program costs.
In mobile SATCOM, form factor directly affects mission viability. A bulky terminal not only takes up valuable space—it can also compromise aerodynamics, mobility, and concealment.
2. The Mobility Challenge: Ku and Ka Band in Motion
Operating in Ku-band and Ka-band while in motion presents unique challenges:
- High Precision Pointing: Maintaining a stable link to fast-moving LEO satellites or long-range GEO targets requires extremely accurate beam steering.
- Environmental Hardening: Antennas must perform flawlessly in vibration-heavy, high-speed, or turbulent conditions.
- Integration Constraints: Platforms like unmanned aerial vehicles (UAVs) or light armoured patrol vehicles have stringent size envelopes for external hardware.
Traditional mechanical gimbaled antennas meet these challenges, but at the cost of large size, high power draw, and increased maintenance. The evolution to electronically steerable phased arrays solves many of these issues—but historically, even these systems have been large, costly, and power-hungry.
3. Novocomms’ Approach: Miniaturisation Without Compromise
This is where Metarray™, Novocomms’ dynamically reconfigurable metasurface phased-array antenna, changes the equation.
- Form Factor Advantage: Metarray™ offers up to 50% size reduction compared to traditional phased-array systems with the same performance specifications.
- SWaP-C Optimisation: Power consumption is reduced by up to 90% compared to legacy arrays—critical for platforms with limited onboard power.
- Flexible Configurations: Available in multiple size formats, with the smallest starting at 25cm x 22.5cm, enabling integration on platforms previously unsuitable for high-performance SATCOM.
- Ku/Ka Compatibility: Seamless operation across both bands ensures interoperability with existing military and commercial satellite networks.
This reduction in size and power doesn’t come at the expense of EIRP, G/T, or beamforming agility. Using the SmarTenna™ algorithm, Metarray™ maintains precise beam control in dynamic conditions, ensuring consistent, high-throughput links.
4. Real-World Impact: Platforms and Use Cases
Military Ground Vehicles:
Light reconnaissance vehicles can now carry high-throughput SATCOM without compromising speed or stealth. Reduced antenna profile also lowers the platform’s visual and radar cross-section.
Aerospace Applications:
Helicopters and fixed-wing aircraft benefit from lower drag, lighter payloads, and the ability to operate at higher altitudes with less impact on performance.
Unmanned Systems (UAV/USV):
Power efficiency is critical for endurance. Smaller, lighter SATCOM terminals directly translate to longer mission durations and reduced battery swaps.
Maritime Operations:
Compact terminals allow for easier installation on smaller vessels and less structural modification for integration, reducing downtime.
5. The Future of Compact SATCOM On-the-Move
As defence, aerospace, and emergency response agencies demand greater mobility and flexibility, terminal miniaturisation will become a defining competitive factor in SATCOM procurement. The platforms of tomorrow—autonomous drones, next-gen patrol vehicles, and compact expeditionary systems—will require terminals that are as agile and resilient as the missions they support.
With Metarray™, Novocomms delivers SWaP-C superiority without sacrificing the high link reliability, throughput, and beam agility required for mission success.
