The Nightingale 1 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.

The Nightingale 1 active phased array payload was selected by CACI International, Inc.’s (NYSE: CACI) (NYSE: CACI) for an upcoming space technology demonstration, customizing the Nightingale systems to demonstrate alternative positioning, navigation, and timing (APNT) waveforms and a tactical intelligence, surveillance, and reconnaissance (TacISR).

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.


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.


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