I meant real-world application.
Orbits are limited due to the required combination of speed and =
altitude. There are a limited number of
achievable altitudes and collision avoidance also creates interesting =
problems in time-slotting for
orbits which are not geostationary.
Geostationary orbits are currently limited to one object per degree of =
earth surface, and even at 4x
that, you could give every satellite a /48 and still not burn through a =
/32.
