How to use vsTASKER to simulate satellite communications

Satellite and Orbit Editing for Space Simulation

vsTASKER includes now orbit definition and propagator to address satellite and spaceships simulations without requiring another product.

Orbits can be defined automatically from TLE description provided by organisms such as NORAD (see here). Once an orbit is defined, a satellite or spaceship can be attached and moved along this orbit using one of the three propagator provided with vsTASKER. If required, user can also define or use its own propagator.

For specific satellites which are not listed by NORAD (military satellites mostly), user can use Kepler parameters to define its own orbits (Geostationary, Molniya…) and move along its own space objects.

With this capability, scenarios can now add satellite communications, ground coverage analysis, satellite to satellite communications, earth shadowing, sun shadowing, ground to space station visibility, intercontinental missile detection and destruction, satellite weapons, etc.

With this functionality:

  • Round earth globe display
  • TLE orbit definition with database
  • Keplerian orbit for manual definition
  • Orbits from low altitude, geostationary to Molniya
  • SGP4 propagator
  • Two-Body propagator
  • J2 propagator
  • Julian time in scenario
  • Terminator computation
