Cache "loses" astropy.units of stored orbit-trajectories #7

Operating System: Linux Debian testing (but virtualenv)

Description

Orbits acquired with get_orbit() have data-values annotated with astropy-units, but only when the orbit is loaded from the web-services. It seems that when orbits are fetched from the (local) diskcache the unit-annotation has been lost.

Breaks on CI :/

FYI, in OrbitViewer I worked around the loss of units this way:

unit = km
if type(sv.values) is Quantity:
    unit = 1
# [..]
sv.values * unit
