Viasat to Equip Embraer C-390 Millennium with Dual-Band SATCOM Terminals for Enhanced Global Connectivity

In a recent announcement, Viasat Inc., a leading satellite communications provider, revealed a groundbreaking collaboration with Brazilian aerospace giant Embraer to bring advanced dual-band SATCOM (Satellite Communication) technology to the C-390 Millennium military transport aircraft. This integration, centered on Viasat's Hybrid SATCOM Approach (HSA), will equip the C-390 with the GAT-5530 terminal, known as KuKarray, enabling seamless and secure communication across diverse mission settings. The partnership represents a significant leap in capabilities for the C-390, particularly in its multi-role mission flexibility and operational reach.

Transforming Connectivity with Viasat’s Hybrid SATCOM Approach (HSA)

The essence of this collaboration is Viasat’s Hybrid SATCOM Approach (HSA), a strategic design that combines Ku-band and Ka-band frequencies to provide robust dual-band communication coverage. The integration allows the C-390 to access both the high-capacity Ka-band and the globally accessible Ku-band networks, expanding the aircraft’s operational versatility. This dual-band feature enables continuous, resilient communication and reduces dependency on a single satellite frequency, ensuring communication continuity even in contested environments.

HSA's advanced multi-band, multi-orbit connectivity also extends beyond Viasat’s proprietary networks to support other government and third-party systems, like the U.S. Department of Defense’s Wideband Global SATCOM (WGS). This adaptability lets the C-390 connect to various government and military networks, such as Mil-Ka, a crucial enhancement for global operations. This compatibility provides vital operational flexibility, offering Embraer’s defense customers connectivity options to address a broader spectrum of mission demands.

Key SATCOM Features Elevate C-390’s Operational Versatility

The GAT-5530, or KuKarray terminal, lies at the core of this transformation. Known for its advanced dual-band capability, the GAT-5530 enables secure, high-throughput connectivity and supports Embraer’s mission requirements with unmatched communication resilience. This terminal aligns with Viasat’s Automated Primary, Alternate, Contingency, and Emergency (APACE) communication protocol, a highly secure and reliable communication system designed for defense environments. APACE empowers the C-390 with enhanced situational awareness, streamlining the flow of mission-critical data across different operational scenarios, from humanitarian relief missions to tactical military engagements.

Additionally, the open-architecture HSA is future-proofed to support other frequencies, such as LEO (Low Earth Orbit) and L-Band networks, making it compatible with emerging satellite systems. This capability ensures that the C-390 can accommodate potential future upgrades without needing significant overhauls, thus preserving Embraer’s commitment to multi-mission adaptability.

Statements from Embraer and Viasat Highlight Strategic Importance

Victor Farah, Senior Vice President of Viasat Government Solutions and Services, emphasized the alignment of Viasat’s SATCOM technology with Embraer’s vision: “Viasat is excited to expand its relationship with Embraer and deliver a hybrid SATCOM solution on the C-390 Millennium platform. Our Hybrid SATCOM Approach design supports advanced airborne connectivity for defense customers seeking reliable, resilient satellite communications in contested environments.”

This sentiment was echoed by Frederico Lemos, Chief Commercial Officer for Embraer Defense & Security, who noted that the C-390 is designed with interoperability and mission versatility in mind: “The C-390 offers interoperability and multi-mission capability off-the-shelf, and Embraer is consistently working to expand the envelope. The selection of Viasat’s hybrid satcom terminal is totally aligned with our vision to deliver reliable global connectivity and PACE communication to end-users.”

Enhancing the C-390’s Multi-Mission Capabilities

The C-390 Millennium has made its mark in various military and non-military settings, including disaster relief, logistical transport, and medical evacuations. The addition of Viasat’s SATCOM technology will augment its flexibility by allowing real-time data transfer and video streaming capabilities for critical decision-making. Furthermore, the strengthened SATCOM capabilities enable interoperability with international forces and aid organizations, enhancing its role in global coalition operations. 

As Embraer and Viasat advance their integration efforts, the C-390 Millennium stands poised to redefine its role in defense and humanitarian applications, reinforcing Embraer’s reputation as a trusted manufacturer of adaptable, technologically advanced military aircraft. Through this partnership, Viasat’s dual-band SATCOM technology will not only improve the C-390’s communication resilience but also extend its operational reach, making it a formidable asset in diverse mission environments worldwide.
