Drawing satellite networks - plot scripts for ns
part of Lloyd's ns work
These scripts allow you to draw topologies of satellite constellation networks
and paths taken by traffic on unprojected or polar
azimuthal equidistant maps of the Earth.
These are for use with the satellite simulation functionality of
the network simulator ns,
as described in Chapter 17 of the
or for use with anything else that outputs satellite and link endpoint coordinates using the same simple text format.
perl 5.003 and xfig 3.2 are required to run these scripts.
A minimum release of ns 2.1b6a, or ns snapshot later than 23 October 1999 with satellite functionality and topology dumping (in
satnode.cc) is needed to generate the output format used by these scripts.
To distinguish different types of links
in different colours, a minimum release of ns 2.1b7, or ns snapshot later than 21 June 2000, is required.

The example plots on this page show the Teledesic 288-active-satellite constellation (Boeing design) at a point in time. You can see the different satellites and two ground terminals as well as
the different types of intersatellite links:
intraplane links, interplane links, cross-seam links as well as ground-to-space links.
You can select from a number of background maps or even generate new unprojected maps
better living through geometry.
