COMMPACK

• S-Band antenna array

• Designed for NASA 6U spacecraft

• Scalable system for intersatellite links

COMMPACK

Cross-link Communications Payload

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 Purp
ose 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.

KEY FEATURES:

  • Autonomous link/network establishment (no external synchronization required)

  • TDD/TDMA (allows seamless scaling of swarm size)

  • Carrier-sense feature (reduces probability of packet collision)

  • Transmit-power and symbol-rate adaptation(saves DC power)

  • Suitable for both military and commercial applications on LEO satellites and airborne platforms

  • CommPack consists of one SDR-1001 Software-Defined Radio and two TRM-4S01 Active S-band antenna arrays

PRODUCT SPECIFICATIONS:

 6U SWARM CONSTELLATION

Four 6U spacecraft will demonstrate critical swarm technologies in LEO for future space exploration missions. Cesium’s ad-hoc network-enabling CommPack will serve as the communications backbone for formation flying, relative navigation, and autonomous reconfiguration demonstrations on-orbit.
