We know that the notion of observational frame of reference has no
meaning in general relativity:

"...the question of precisely what Einstein discovered remains
unanswered, for we have no consensus over the exact nature of the
theory's fondations. Is this the theory that extends the relativity of
motion from inertial motion to accelerated motion, as Einstein
contended ? Or is it just a theory that treats gravitation
geometrically in the spacetime setting ?"

general relativity: eight decades of dispute, Rep. Prog. Phys., 56,

"Of special importance for our purposes is that each frame of
reference has a definite state of motion at each event of spacetime"
My document present the theory that extends the relativity of motion
from inertial motion to accelerated motion and I hope you will try to
learn more about its contents. It is built around the notion of
observational frame of reference.
For now I have some dificulties in English and I'd rather write in
French. The document :
