Satellite signal quality and accuracy would not apply to the "jump" problem in this case as the problem seems to occur in simulation mode.

It's more likely the "magnetic" snap to road positioning that gives circular events between routing and simulated satellite positioning calculation. Often seen in roundabouts and city streets with multiple junctions where the automatic zoom also affects visual feedback of the problem.
