I wonder just how small the differences are: both longitudinally and the even smaller transverse component ? too.
I suppose we are in the realms of micro gravity here.
Yes its the reference frame that's accelerating constantly toward the centre of the earth.
CAT III Edit: [I'm not being pedantic but imagine "Big imagine" trying to align a GPS at the North/South pole? - It would be impossible to get a fixed bearing because of the Earth's rotation. Now someone will prove me wrong from real life experience.]
[New edit: Sorry I'm wrong GPS relies on Geostationary Sats: They would be still fixed at either pole: ooops.]
