Gilat's New Antenna Aims to Secure the Unmanned Battlefield's Lifeline

PETAH TIKVA, Israel – June 02, 2026 – In a world increasingly defined by autonomous systems and data-driven warfare, the invisible threads of connectivity that link these platforms to their operators have become both a critical asset and a glaring vulnerability. Addressing this challenge head-on, Gilat Satellite Networks has announced that its defense division will unveil a significant advancement in tactical communications at the upcoming Eurosatory 2026 defense exhibition in Paris: the RaySat Viper Ka Electronically Steered Antenna (ESA).

This new terminal, designed for tactical unmanned platforms, is more than just an incremental upgrade. It represents a direct response to the escalating electronic warfare environment where maintaining resilient, low-latency communication is paramount for mission success. As nations pour billions into drone fleets and autonomous vehicles, the hidden cost of this progress is the fragility of their control links. Gilat’s latest offering signals a strategic push to harden this Achilles' heel of modern military operations.

The High-Stakes Race for Resilient Connectivity

The proliferation of unmanned systems across air, land, and sea has fundamentally altered battlefield dynamics. However, their effectiveness hinges on a constant, reliable stream of data. This dependency creates a lucrative target for adversaries. Electronic warfare tactics like signal jamming and spoofing can sever the link between an operator and a multi-million-dollar unmanned aerial vehicle (UAV), rendering it useless or, worse, turning it into a liability. The global UAV satellite communication market, valued at over $7 billion in 2025 and projected to exceed $12 billion by 2035, is a testament to the critical importance of this sector.

Legacy satellite communication systems often struggle in these contested environments. Traditional mechanically steered antennas can be slow to track satellites, and reliance on a single satellite or constellation creates a single point of failure. For tactical platforms where size, weight, and power (SWaP) are severely constrained, bulky and power-hungry terminals are non-starters. The demand is for a solution that is small, agile, and, above all, resilient.

“Operational forces increasingly depend on unmanned platforms that require resilient and uninterrupted very low-latency connectivity across highly dynamic operational environments,” said Gilad Landsberg, President of Gilat Defense, in the company's announcement. His statement underscores a fundamental truth of 21st-century conflict: without secure data, digital superiority is impossible.

The Viper ESA: A Multi-Orbit Answer

The Viper Ka ESA is Gilat's answer to this complex problem. Developed by its subsidiary RaySat, the terminal leverages Electronically Steered Antenna technology. Unlike mechanical dishes that physically move to track satellites, ESAs steer their beams electronically, offering near-instantaneous tracking, higher reliability with no moving parts, and a low-profile design ideal for minimizing aerodynamic drag on aerial platforms.

The most significant feature of the Viper is its multi-orbit capability. The antenna can dynamically connect to satellites in Geostationary (GEO), Medium Earth Orbit (MEO), and Low Earth Orbit (LEO) constellations. This is a game-changer for operational resilience. A drone could use a LEO constellation for very low-latency video and control in a high-threat area, then seamlessly switch to a more stable GEO satellite for data transfer if the LEO network is compromised or unavailable. This ability to 'hop' between orbits makes the communication link exponentially harder to disrupt.

“Having a terminal that can seamlessly switch between LEO for low-latency and GEO for reliability is no longer a luxury; it’s a requirement for survival in a peer-to-peer conflict,” a defense communications analyst noted. The Viper Ka is designed to support not only current commercial Ka-band constellations but also emerging military-focused networks, ensuring future-proofing for defense clients.

A Strategic Play in a Booming Defense Market

The launch of the Viper Ka is not an isolated event but a calculated move within Gilat's broader defense strategy. The company formed its dedicated Gilat Defense division in early 2025, consolidating its expertise to specifically target the growing demand from the U.S. Department of Defense and allied forces. This focus appears to be paying off.

Gilat reported a 20% year-over-year revenue increase in the first quarter of 2026, with management citing very strong demand for mobile and transportable SATCOM systems. The company has recently secured significant contracts, including a $9 million order from Israel's Ministry of Defense and over $7 million for its solutions to support the U.S. Department of War. The Viper antenna complements Gilat’s existing portfolio of modems, ground terminals, and power amplifiers, allowing the firm to offer a comprehensive, end-to-end solution for military clients.

This strategic positioning is timely. Global defense spending is soaring, projected to top $2.6 trillion by the end of 2026, with a significant portion allocated to autonomous systems and the network-centric technologies that enable them. By presenting its advanced connectivity solution at Eurosatory, one of the world's premier defense expos, Gilat is placing its technology directly in front of key decision-makers at a time of peak demand. The presentation at Hall 6, Booth B280, will be closely watched by military procurement officers and industry competitors alike, as it represents a key piece in the puzzle of achieving true multi-domain superiority on the future battlefield.
