Multiple/Auxiliary Payloads

Multiple or Comanifest

Multiple and comanifesting are common. Payloads can be supported in a dual payload attach fitting or the lower satellite(s) may be load bearing.

Auxiliary Payloads

Auxiliary payloads can be accommodated depending on available performance and volume.
