Thanks to the retiring of the adcs tag we now have:
attitude 211 questions:
Questions on ascertaining, predicting, and controlling spatial orientation and rotation of spacecraft, and on forces that affect spatial orientation.
attitude-determination-and-control 99 questions:
Sensors, systems, strategies, algorithms and mathematics relating to BOTH determining AND controlling the attitude (3D orientation) of spacecraft.
I'd originally thought that the attitude tag was for questions only about attitude and did not contain questions about it's control so there was still a distinction, however the two following fancy searches show that the separation of usage between the two tags may not be clean:
- [attitude] -[attitude-determination-and-control] control is:question returns 84 question posts that have the attitude tag but not the attitud-determination-and-control tag but yet still contain the word "control".
The first few returned are clearly about control:
- How powerful are reaction control wheels?
- Attitude control with cold gas thrusters
- Time scale separation and cascading control loops
- Dragon launch escape: roll control?
- How to select/design a control algorithm for spacecraft attitude control?
I see two very different strategies for resolving this.
- Heavy-duty, wholesale retagging of hundreds of questions, either by laborious reading and manual retagging or by experimental script-o-magic or temporary botification
- A second, further merging of these two tags into attitude-determination-and-control.
The first is intriguing but I fear it will be impossible to maintain, future question authors may randomly choose one or the other, though it could be reduced by careful rewriting of the usage guidance.
Question: Should we clean up and separate 'attitude' and 'attitude-determination-and-control' questions, or just further merge these last two tags?
