PA-Ka is for spacecraft downlink and for links between spacecraft. The same terminal fits the SF family.

A communications terminal is one part of an end-to-end link. Beam steering, available power, thermal limits, pointing, and the receiving network must be considered with the data that needs to move. The architecture follows the contact geometry and the mission's communications priorities.

  • Electronic steering

    The beam moves electronically, within the pointing range of the mission.

  • Throughput

    The terminal is designed for a high-rate link.

  • Common fit

    Power and data interfaces are shared across SF-150, SF-500, and SF-GEO.

Bus family

Four buses, by class.

  1. SF-12Rideshare
  2. SF-150ESPA-class
  3. SF-500Microsat
  4. SF-GEOGEO-class
