I'm using a poliastro orbit and I want to find the distance from a satellite to a lat long coordinate on earth with height h above sea level.
From the twobody orbit, I am using https://docs.poliastro.space/en/stable/api.html#high-level-api
r (Quantity) – Position vector wrt attractor center.
I am planning to convert lat long coordinates to a position vector with respect to the center of the earth so I can simply use the magnitude of the differences between the vectors to get the distance. (unless there is an easier way?)
Converting from longitude\latitude to Cartesian coordinates
I tried using the conversions mentioned here but this presents it in a different format.
How can I convert lat, long, h coordinates into a position vector with respect to the center of the earth? Thanks.
