HALO:

 

The operational HALO System is an independent space-based capability to manufacture large curved apertures and arrays on-orbit for small satellite buses. This approach enables the integration of affordable, lower-mass buses optimized for specific mission packages with large antennas or sensor backplanes robotically fabricated on-orbit that require neither launch survivability nor the resources of traditional large satellites. The HALO System thus enhances the resiliency of the space network by increasing the mission capability of small satellites without increasing the resource footprint of the mission.

 
In a stepwise process, the payload bus equipped with HALO attaches pre-packed reflector panels to fabricated support structures and manufactures an optimized feedhorn boom with integral power and data.

Operationally, the HALO System widely adaptable to mission requirements. It is designed to be employed on any delivery bus with sufficient on-board power, communications, payload pointing, and orbit maintenance capability. HALO utilizes the vehicle as a host platform to manufacture, assemble, and deploy large structures such as antennas, sensor backplanes, and feedhorn booms. HALO includes the feedstock containment, extended structure manufacturing devices, component stowage, and robotic assembly tools necessary to accomplish these tasks.

Applications:

 
 
  • Manufacture and assemble ultra-large RF reflectors in the smallest form factor possible

  • Develop and demonstrate curved structure manufacturing in microgravity

    • Demonstrate sufficient precision for RF surfaces

  • Develop and demonstrate robotic assembly capability that results in a functional RF reflector antenna

  • Determine CONOPS for various mission scenarios


The first concept is the ‘Mobile Factory.’ In this scenario, the HALO System carries multiple deployable satellites to orbit, manufactures the specific antennas, robotically integrates those antennas with their respective payloads, and delivers the complete mission packages to their final orbits.

 

The second concept is the ‘Multifunctional Node.’ In this scenario, the HALO System hosts multiple mission electronics packages simultaneously in permanent installations. Once on station in its final orbit, the HALO System then manufactures and installs on the OMV the various antennas, phased array structures, and any additional support infrastructure (e.g. additional power and/or cooling apparatus) required to support the mission packages.

The third concept is the ‘Maximum Aperture.’ In this scenario, the HALO System hosts an optimized and fully integrated mission package and manufactures a single, dedicated large aperture for the mission that takes full advantage of the maximum envelope for power, data, vehicle control, and manufacturability.
