About our mission

Active Phased Arrays

Maximum Versatility On-Orbit

System Capabilities

Vireo: Multi-beam Communications Payload

Dynamic Frequency-to-Beam Allocation

Maximize data rates and spectral efficiency by dynamically assigning frequency-to-beam allocations.

On-Orbit Reconfigurability

Dynamically adapt coverage areas and support future capability with a fully software-defined payload.

Flexible Beam Management

Divide RF power among beams, flexibility defining per-beam allocation to provide improved quality of service.

Mechanical Advantage

Compact, flat-panel form factor reduces integration time and complexity to install, maintain and service.

Thermal Management

Simplify the thermal management system by spreading heat over the full surface area of the array.

Beam-Steering and Beam-Hopping

Rapidly hop and steer beams to improve spectrum utilization and increase user capacity.

Mass Manufacturable

Affordable in quantities from one to thousands utilizing commercial PCB manufacturing techniques.

Multiple Independent Beams

Maximize capacity and frequency reuse with multiple independent beams.

Jam Resistant

Apply pattern nulls to cancel interfering signals, improving signal-to-noise ratio.
