Requtech Upgrades Ka-band SATCOM Hub to Expand European Defense Connectivity

Swedish satellite communications specialist Requtech has launched a significant upgrade of its Ka-band satellite communications (SATCOM) hub infrastructure. The move is part of a broader strategic initiative to expand its support for defense and government users across Europe amid rising demand for resilient, high-throughput connectivity solutions tailored for mobile and tactical operations.

Strategic Infrastructure Upgrade at the Heart of Requtech’s Expansion

Requtech’s Ka-band hub upgrade is centered on enhancing its existing ground station infrastructure in Sweden. The company aims to increase bandwidth capacity, reduce latency, and improve interoperability with both commercial and military satellite constellations operating in the Ka-band frequency spectrum (26.5–40 GHz). This spectrum is increasingly favored by defense customers due to its ability to support high-data-rate applications such as ISR data transmission, video conferencing from mobile command posts, and real-time battlefield situational awareness tools.

The upgraded hub will serve as a key node in Requtech’s expanding network of Very Small Aperture Terminal (VSAT) solutions designed for land vehicles, naval platforms, and airborne assets. According to the company’s press release on May 21st 2024, the retrofit will also enable seamless integration with next-generation High Throughput Satellites (HTS) and Low Earth Orbit (LEO)/Medium Earth Orbit (MEO) constellations.

Driving Factors: European Demand for Mobile Tactical SATCOM

The upgrade comes amid a surge in demand from European defense ministries seeking greater mobility and resilience in their C4ISR architectures. As NATO members modernize their command-and-control systems under evolving operational concepts such as Multi-Domain Operations (MDO) and Joint All-Domain Command and Control (JADC2), SATCOM plays an increasingly critical role in ensuring secure connectivity beyond line-of-sight (BLOS).

Sweden’s recent accession to NATO further incentivizes interoperability investments by domestic firms like Requtech. By aligning its infrastructure with NATO STANAG protocols and encryption standards such as TRANSEC/COMSEC compliance for tactical terminals, Requtech positions itself as a key enabler of allied communications architecture across Northern Europe.

Technical Enhancements: From Antenna Control Units to Beam Switching

The retrofit includes several technical upgrades:

Adaptive Modem Integration: Support for DVB-S2X modems capable of dynamic link adaptation based on channel conditions.
Antenna Control Unit (ACU) Enhancements: Improved pointing accuracy and faster acquisition times for moving platforms using stabilized antennas.
Beam Hopping & Switching: Compatibility with HTS spot-beam architectures allows terminals to switch beams seamlessly without service interruption.
Cybersecurity Hardening: Implementation of secure boot protocols and remote terminal management with end-to-end encryption.

This level of flexibility is essential for supporting mobile ground forces operating in contested or degraded environments where electromagnetic interference or jamming may be present. It also facilitates hybrid SATCOM architectures that combine GEO satellites with emerging LEO/MEO networks such as OneWeb or SES O3b mPOWER.

Tactical Applications Across Domains

The upgraded hub will directly support Requtech’s range of ruggedized terminals including its RQT-VSAT series designed for armored vehicles and maritime vessels. These terminals are engineered for rapid deployment (<10 min setup), auto-acquisition capability under movement (on-the-move), and MIL-STD-810G environmental compliance.

Key use cases include:

Battalion-level HQs: Deployable command posts requiring broadband uplinks for ISR feeds from UAVs or forward observers.
SIGINT Platforms: Transmission of large volumes of ELINT/COMINT data back to national processing centers via secure Ka-band links.
Civil-Military Coordination: Emergency response scenarios where civil authorities require interoperable comms with military units during disasters or hybrid threats.

SATCOM Market Dynamics in Europe Favor Agile Providers

The European tactical SATCOM market is becoming increasingly competitive as legacy programs give way to more agile procurement models favoring modularity and vendor-neutral solutions. Companies like Airbus Defence & Space, Thales Alenia Space, Kymeta Corp., GetSat Ltd., and now Requtech are all vying for contracts tied to vehicle-mounted or manpackable terminals that can operate across multiple bands (X/Ku/Ka).

A notable trend is the shift toward dual-use architectures that leverage commercial satellite infrastructure while maintaining military-grade security overlays — a model supported by NATO’s Federated Mission Networking doctrine. For smaller players like Requtech, success hinges on offering cost-effective yet technically advanced solutions that can plug into both national defense networks and multinational coalition frameworks without extensive customization overheads.

Future Outlook: Toward LEO-Ready Architectures

The current upgrade lays the groundwork for future-proofing Requtech’s offerings against the backdrop of rapid LEO proliferation. With operators like Starlink Government Services entering defense markets — offering low-latency global coverage — terminal vendors must ensure compatibility with electronically steered antennas (ESA), multi-orbit switching capability via SDN-based orchestration layers, and cloud-native NMS platforms capable of managing heterogeneous networks at scale.

If successfully executed by Q3 2024 as planned, this hub modernization could position Requtech not only as a regional player but also as a niche integrator capable of supporting pan-European defense initiatives such as PESCO projects focused on strategic autonomy in space-based communications infrastructure.
