“Componentized GeoPose” Request

Summary

Targeted standard: OGC GeoPose 1.0
Description:

Using an implementation of the Components Request, redefine each standardization target referencing the Components. Since this is already the structure, it involves only editorial changes to change SDU references to Component references.

Motivation

This is the core use of the SDUs, redefined as Components, to specify the eight GeoPose standardization targets. Adoption of this framework additionally supports standalone use of Components in other standards and applications.

Background 1/1

Composition

position+angles => Basic YPR
position+quaternion => Basic Quaternion

With Timestamps

position+angles+time => Timestamped Basic YPR*
position+quaternion+time => Timestamped Basic Quaternion*

Notes

The order of appearance of a block has no significance
* = not in GeoPose 1.0
GeoPose 1.0 does not prohibit timestamp
Main change is to make the blocks first class objects
