DMSC Visualizer

A library to visualize (keplerian) orbital movements of a satellite network in 3D using OpenGL® 3.3.
Optimization algorithms to minimize the time needed to perform a set of scheduled intersatellite communications are implemented. In particular, the central mass as an obstacle and the necessary turn costs of the satellites are taken into account (algorithmic problem: Dynamic Minimum Scan Cover).

Real world instances

The provided real world instances are based on the idealized structure of the corresponding satellite constellation. In particular, the state vectors do not correspond to a more precisely specified point in (real)time. All instances do not contain any intersatellite links.

instance	# satellites	orbital altitude
Galileo	30	23.222 km (MEO)
Iridium Next	66	780 km (LEO)
