Vireo is a multi-beam active phased array system for high-throughput satellites. The design addresses the state-of-the-art performance requirements for constellations under aggressive SWaP-C targets.
A major feature of the Vireo design is its cutting-edge power usage and power saving capabilities. The system meets strict power consumption requirements during full-capacity operation and allows for power reduction with full per-element and per-beam control. In the transmit version, the power amplifier architecture was specifically designed to reduce the effects of active impedance presented by the antenna, as well as to address the complexities of taper implementation while maintaining high power-efficiency – a key to minimizing overall constellation cost.

Nightingale I is a fully integrated Ka-band phased array communication system providing a complete hardware and software solution for high-speed RF links with a dynamically steerable beam. The system includes an active phased array antenna as well as a software-defined radio, single-board computer, power converter, and RF front-end—all integrated into a seamless high-speed downlink solution.
The complete-system approach and small form-factor allow for plug-and-play integration with LEO spacecraft and airborne platforms, while the tile architecture allows for system scaling and adaptation to mission requirements. Per-element array control enables on-orbit optimization of power and beam shape.
 

The CommPack Cross-link Communications Payload uses building blocks from Cesium’s modular device ecosystem to enable mobile ad-hoc networking in space. This swarm technology is paving the way for future small satellite missions to the Moon, Mars, and beyond. The system consists of the SDR-1001 and two active S-band antenna arrays (TRM-4S01). The OTS Cesium General Purpose Modem loaded into the SDR-1001’s FPGA provides robust BPSK/QPSK inter-satellite links between spacecraft in a swarm.
The CommPack was designed as an intersatellite link for NASA Ames, but may be reconfigured as required to support your concept of operations.
