Multiple Trajectories

The software-defined nature of Skydel enables multiple instances of the GNSS simulator to run on the same or multiple computers. This brings research and test labs interesting possibilities to create advanced simulation setups.

When synchronizing simulators, parameters such as radio and antenna settings, vehicle trajectories or interference transmitters are shared between all instances. SDX provides a fine level of control on how each instances connect to each other to perform the synchronization.
