IN Brief:
- Orbit has received multi-million-dollar international orders for 5.5-metre and 6.1-metre GAIA 100 ground stations.
- The newly disclosed 6.1-metre system adds higher gain, improved link margins, and enhanced Ka-band tracking.
- Kratos acquired Orbit in March 2026, adding physical satellite ground infrastructure to its microwave and digital portfolio.
Kratos Defense & Security Solutions says its Orbit Communication Systems business has received multi-million-dollar orders from several international customers for GAIA 100 tri-band ground stations, covering both 5.5-metre systems and a newly disclosed 6.1-metre configuration.
The GAIA family supports S-, X-, and Ka-band operation for Earth observation, satellite communications, defence, and wider space applications. The new 6.1-metre antenna is designed to provide higher gain, improved link margins, and enhanced Ka-band tracking while retaining the common architecture used elsewhere in the product family.
Ka-band can provide substantial communications bandwidth, making it attractive where operators need to move larger volumes of satellite data. The higher frequency also places demanding requirements on antenna pointing because narrower beams allow less tolerance for tracking error than many lower-frequency links.
That problem is particularly acute when a ground station follows a spacecraft in low Earth orbit. The antenna has to acquire and track a fast-moving target across the sky while maintaining sufficient pointing accuracy to preserve the link throughout the pass.
Orbit’s 6.1-metre design incorporates its Auto Track technology, combining radio-frequency tracking with the antenna-control architecture. The company says the system maintains satellite alignment through the pass and is intended to support the pointing accuracy required for Ka-band communications.
The antenna also uses an integrated radome to protect critical mechanical and radio-frequency components from environmental exposure. For permanently installed ground infrastructure, weather protection can influence availability, maintenance intervals, corrosion, mechanical reliability, and the consistency of precision tracking over a long operating life.
GAIA is designed to support low-, medium-, and geostationary-Earth-orbit missions. A system family able to cover several orbit classes and frequency combinations gives operators more flexibility when building ground networks, although each mission will still place its own demands on antenna size, link budget, tracking behaviour, redundancy, and site location.
Common architecture across several antenna sizes can reduce part of the support burden. Control systems, operating procedures, software, spare parts, and technician training can be shared more readily than they can across unrelated antenna families, while individual sites can select the aperture needed for the link budget.
The orders arrive five months after Kratos acquired Orbit in March 2026. Orbit added satellite communications, tracking, and communications-management technologies to a Kratos portfolio that already included radio-frequency, microwave, digital, and space-system capabilities.
Ground stations are a physical constraint within otherwise increasingly software-defined space architectures. Satellites and digital networks may be reconfigured remotely, but antennas still have to acquire spacecraft, maintain accurate pointing, handle the required frequencies, survive their local environment, and remain available through repeated passes.
For defence customers, those requirements intersect with efforts to build more resilient space communications. Distributed satellites, uncrewed systems, sensing networks, and military command architectures all increase the quantity of information moving through the ground segment, while resilience can require more geographically dispersed sites and greater ability to shift links between assets.
The current orders are not exclusively military. Kratos lists Earth observation, New Space, satellite communications, and defence among the target applications, and the international customers have not been identified. Exact values, delivery dates, system quantities, and the split between 5.5-metre and 6.1-metre antennas have also not been disclosed.
That mixed customer base can still support defence industrial capacity by increasing production volume and operating experience around common equipment. Commercial installations can contribute manufacturing demand and reliability data, while military configurations can add security, resilience, and mission-specific integration requirements where needed.
The 6.1-metre system also reflects the pressure that higher data volumes place on the ground segment. Investment in satellites does not create useful communications capacity if ground equipment cannot track them accurately or maintain adequate link margins, particularly at Ka-band frequencies.
Kratos’ acquisition of Orbit gives the group direct access to that hardware layer rather than limiting its role to components and digital infrastructure around the link. The new orders provide an early test of the commercial logic: whether Orbit’s ground-station products can expand alongside the wider Kratos space and defence portfolio while retaining a common, supportable platform architecture.
