ATM vectors coordinates are different variables the orbit dataset.
I argue that vectors will be more useful if distributed as a single variable with "x", "y" and "z" (or 0, 1, and 2) as a coordinate dimension:
<xarray.Dataset>
Dimensions: (azimuth_time: 17, i: 3)
Coordinates:
* azimuth_time (azimuth_time) datetime64[ns] 2020-03-15T17:04:38.537823 .....
* i (i) int64 0 1 2
Data variables:
position (azimuth_time, i) float64 5.659e+06 5.618e+06 ... 4.926e+06
velocity (azimuth_time, i) float64 -4.072e+03 -4.138e+03 ... -5.078e+03

This way vectors can be passed around like xr.DataArray and operations like the dot products are trivial: (p1 * p2).sum("i")
