I'm trying to get the velocity of an EarthSatellite loaded from a TLE. For example:
```
from skyfield.api import Topos, load
import numpy as np
ts = load.timescale()
stations_url = 'http://cel…

The load.tle cache appears to only look at the filename, and not the complete URL. So the following code:
```
from skyfield.api import Topos, load
stations_url = 'http://celestrak.com/NORAD/ele…

An update to Skyview TLE dictionary returned from load.tle() means that the keys have been changed from satellite names, to ID numbers. This means any code that refers to the satellite name, such as t…

I was suggested to use PyEphem as the best way to propagate the orbit of a satellite.
I'm going to propagate in 1 year, considering the effects of Moon, Sun, zonal harmonics and probably, Jupiter …

We should add logging. It's almost impossible to understand what is going on behind the scenes, thus tracking any misbehavior.
We don't need a full-featured logger like [Boost.Log](http://boost-log.s…

For Earth satellites in high orbits, the effects of the Moon become important and the time between published TLE epochs become longer. Satellites like Spektr-R and IBEX have 10-day orbits for example.…
