Satellite Communications

With the Satellite module of vsTASKER, doing satellite communications assessment in real or fast time is simple.

Import any satellite from TLE data or define the orbit using the six Keplerian elements than use our SGP4 or Two-Body propagator to accurately predict the position of the satellite in space for any Julian time.

Add to the satellite emitting antennas, payloads, signals forces and you can estimate the ground reception coverage according to several criteria including earth curvature, atmosphere disturbance and sun interference.
Communication links between satellites or with ground stations can be simulated for any kind of studies (ground coverage, time window for data transfer, quality assessment, etc.)


  • Any TLE or user define orbit using Kepler elements
  • SGP4 or Two-Body propagators
  • OpenGL 3D globe or OsgEarth for visualization
