A method for controlling a vehicle 100 includes generating, by a primary computing system 110, a nominal trajectory from a location in order to achieve a mission goal and a fall back trajectory from the location in order to safely stop the vehicle. The nominal and the fall back are identical between the location and a divergent point and where the nominal and the fall back diverge after the divergent point. The fall back is sent to and received by a secondary computing system 210. The secondary computing system waits for an updated trajectory from the primary computing system while controlling the vehicle according to the fall back. When the vehicle reaches a threshold point on the fall back, or a predetermined threshold period of time from a time when the fall back trajectory was received has passed, and an updated trajectory has not yet been received by the secondary computing system, the secondary computing system continues to control the vehicle according to the fall back in order to safely stop the vehicle.
