A safety check method for checking a neural network output state onboard a spacecraft includes executing a neural network model onboard a spacecraft, which includes calculating a neural network output based on a current navigation state of the spacecraft, propagating the navigation state with the neural network output to a next target epoch to determine a next navigation state of the spacecraft, and evaluating whether the neural network output and the next navigation state are within predetermined bounds. When the neural network output and the next navigation state are within the predetermined bounds, the method is incremented to a next tick. When the neural network output and the next navigation state are determined to be outside the predetermined bounds, a corrective action may be taken.
