This is the third  nanosatellite project for SERC and USC intended to fly new payloads and demonstrate various control and communications techniques.  A new B-Dot control algorithm will be demonstrated for optimal stability control with low power using torque rods, a rotating multi-packetized beacon transmission source to prove backup to the primary communications system, and data store and forward software to be demonstrated for non-consistent ground contacts.  The Cubesat bus is a MISC-2 variant, a sister of the Aeneas design and will use the same flower petal configuration for primary solar array power. Some upgrades to this bus versus Aeneas include:

  • Upgraded multi-packet beacon signals that rotate through constantly all data parameters during powered portion of orbit.
  • New payload electronics card (PEC) that has new power convertors and switches for custom control of the payload bay.
  • New transmitter with higher downlink performance.
  • Upgraded software for brownout and low power modes.
  • New thermal blanket on sun face of satellite for thermal balance of electronic boards.

The bus was completed sans payload in mid-2019. Flight development team photo from left to right, In clean room are Rahul Rughani, Justin Du Plessis, Sophia Bernstein and Denis Healy, Kneeling outside is Lizvette Villafana, Gedi Minster, Piyush Patil, David Barnhart, and standing are Jeremy Allam, Michal Moruzzi, Rebecca Rogers, Kyle Clarke and Sri Narayanan.
