QR1 is focused on orbital design and heavily relies upon STK.  Familiarity with the Orbital Parameters is recommended to achieve the best results.  The QR1 section is organised into Series.  Each series has 2 recommended lessons (one on STK and one on Spreadsheets) and offers 3 scenarios based around those lessons.  The series are designed to be 'building block' and assume a student is familiar with the previous series skills.  Therefore, it is advised to begin with A Series and progress onward.  

Series A - E can be fully worked with the Basic Version of STK

Series F can be worked with the Basic Version, but can be supplemented with the Pro

Series G and beyond require the Pro Version of STK to work
