Vireo

Multi-Beam Communications Payload

The global demand for data has never been higher. Optimize throughput with our modular, scalable Vireo payloads. Cutting-edge power and bandwidth allocation optimize your satellites’ resources.

Key Features

Multi-Beam Operation

Up to 16 independently steerable beams allow for maximum frequency reuse and throughput for seamless connectivity with many simultaneous users.

Fast Beam-Hopping

Near instant beam hopping further divides each beam in time, allowing capacity to be shared and focused across the field of view maximizing throughput and quality of service to specific regions.

Full-Duplex Operation

A dedicated box for transmit and another for receive enable simultaneous uplink and downlink to every user. Additional boxes increase the total number of beams and polarizations.

Software-Defined Flexibility

The payload is controlled by a rich software experience that controls beam planning, steering, shaping, and hopping, as well as power optimization that can be updated dynamically and combined with any onboard baseband processor.

Commercial, Civil, and Defense Applications

Providing options that support both commercialand defense Ka-band frequencies,Vireo is uniquely suited for a wide range ofmissions across multiple domains

LEO, MEO, and GEO Configurations

Vireo offers a scalable architecture for multiple orbits, meeting unique customer requirements for element spacing, power levels, and environmental performance.
