What you will be able to do
- Choose between centralized, ring and bus architectures with reasons
- Derive flight software functional requirements from a mission requirement
- Compute onboard storage and minimum downlink rate from mission parameters
- Classify radiation effects and specify the right mitigation for each
Prerequisites
- introduction-to-space-systems
Syllabus
Module 1
Architecture and requirements
What the OBC does, how it is wired to everything else, and what space demands of it.
Module 2
Data budgets and radiation
The calculation every mission does, and the environment that breaks computers.
Assessment
OBC and data handling check
Graded. The data budget questions use the forest-fire mission from the course.
6 questions, graded once you are signed in.
