$\begingroup$ Matrices need fewer math operations if your inputs/outputs are vectors (star sightings, magnetometer observations, torques, etc.). Tradeoffs... $\endgroup$John Doty– John Doty2026-03-31 15:41:18 +00:00Commented 13 hours ago

4$\begingroup$ This doesn't seem to address the iterated vs integrated part of the question. $\endgroup$Organic Marble– Organic Marble2026-03-31 17:28:55 +00:00Commented 11 hours ago

$\begingroup$ Nitpick: rotations don't cover all of quaternions, they cover specifically the unit quaternions. The additional constraint of unit magnitude means that unit quaternions can be represented by three quantities and the fourth determined by convention as a versor $\endgroup$Erin Anne– Erin Anne ♦2026-03-31 17:54:16 +00:00Commented 11 hours ago

2$\begingroup$ The question is about "using iterated rather than integrated euler angles"... Where is this addressed in your answer? Why the upvotes for a not answer? $\endgroup$sophit– sophit2026-03-31 20:36:51 +00:00Commented 8 hours ago

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. orbital-mechanics), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
