Systems Engineering

The UNITE CubeSat follows a systems engineering structure and the NASA project lifecycle guidelines. Per the NASA requirements of being an undergraduate, interdisciplinary team, students have been selected from majors including electrical and mechanical engineering, physics, and computer science. Each student utilizes their respective knowledge for their subsystem. Listed below are the reviews completed or to be completed for the project lifecycle.

 

Concept Review (11/17/2016):

“The CR will affirm the mission need and examine the proposed mission’s objectives and the concept for meeting those objectives.”

-NASA Systems Engineering Handbook

UNITE’s Concept Review was held at the University of Southern Indiana and presented via WebEx to the review panel established by our NASA point of contact. The CR has been successfully passed, including the closure of all associated action items.

 

Preliminary Design Review (2/24/2017):

“The PDR demonstrates that the preliminary design meets all system requirements with acceptable risk and within the cost and schedule constraints and establishes the basis for proceeding with detailed design.”

-NASA Systems Engineering Handbook

UNITE’s Preliminary Design Review was held at the University of Southern Indiana and presented via WebEx to the review panel established by our NASA point of contact. The PDR has been successfully passed, including the closure of all associated action items.

 

Critical Design Review (6/13/2017):

“The purpose of the CDR is to demonstrate that the maturity of the design is appropriate to support proceeding with full scale fabrication, assembly, integration, and test, and that the technical effort is on track to complete the flight and ground system development and mission operations to meet mission performance requirements within the identified cost and schedule constraints.”

-NASA Systems Engineering Handbook

The UNITE team travelled to Wallops Flight Facility to present their Critical Design Review.  The CDR has been successfully passed, pending closure of all associated action items.

 

Mission Readiness Review (11/17/2017):

During the MRR, the project needs to demonstrate that:

  • The flight vehicle is ready for flight.
  • The hardware is deemed acceptably safe for flight (i.e., meeting the established acceptable risk criteria or documented as being accepted by the PM and DGA).
  • Flight and ground software elements are ready to support flight and flight operations.
  • Interfaces are checked out and found to be functional.
  • Open items and waivers have been examined and found to be acceptable.
  • The flight and recovery environmental factors are within constraints.
  • All open safety and mission risk items have been addressed.

UNITE’s Mission Readiness Review is scheduled for November 17, 2017. The team is currently working on integration and testing of flight hardware to prepare for the MRR.
