Appendix B / Frames of Reference<br />

_ _<br />

APPENDIX B<br />

15 FRAMES OF REFERENCE<br />

The Frames-of-Reference (frames) located at the key geometrical points<br />

defined in Appendix A are defined here. Frames fall into 3 groups: Earth<br />

referenced including the Celestial (Inertial) and satellite frames, missile, and<br />

target located frames. Frames are key in the specification of vectors and<br />

frame related matrices such as the state vector covariances introduced in the<br />

Glossary, relating the generic nomenclature therein to the air-defence<br />

application.<br />

All the frames listed in Figure 15-1 are defined by orthogonal vectors<br />

(X , Y , Z), notation reserved for principal axis identifiers. Transformation<br />

between frames requires only proper (right-handed) rotations.<br />
