Steerable Single-Beam
Communications System

The Nightingale active phased array payload is a complete communications payload solution requiring only data and power connections. Built with modular, software-defined digital components, it provides maximum flexibility through standard software programming tools. It supports TDD (time division duplex) communication and mission data downlink. Combine with S-Band antennas for a fully integrated TTC and mission data solution.

Key Features

at Scale

Fully integrated payload certified to NASA GEVS standards, leveraging volume manufacturing techniques, and available at commercial scale.

Scalable Antenna Solution

Multiple active phased array tiles can combine for improved RF performance, increasing EIRP by 6dB and G/T by 3dB each time the antenna aperture doubles in surface area.

Software-Defined Reconfigurability

Utilize standardized DVB-S2, DVB-S2X, and CCSDS waveforms or design and integrate your own with the integrated, fully reprogrammable software-defined radio and single-board computer.

Full-Stack Communications

Turnkey configurations implement a full communications stack providing an Ethernet-to-RF solution with fully documented APIs for commanding the digitally steerable antenna array.

Rugged and

Compact designs are inherently more rugged and better suited for challenging space and airborne environments

Supporting Mission Success

Every payload comes with a full suite of documentation including CAD models, mechanical ICD, electrical ICD, a programming guide and access to our engineers.
