an unfinned envelope configured for lighter than air operation;

two or more propulsion elements coupled with the unfinned envelope, each of the two or more propulsion elements are configured to provide independent propulsion to the unfinned envelope;

at least one navigation sensor configured to monitor an actual flight path of the unfinned envelope;

at least one perturbation sensor configured to monitor one or more perturbations of the unfinned envelope; and

a navigation controller configured to guide the unfinned envelope with coordinated propulsion of the two or more propulsion elements, the navigation controller includes:

a navigation comparator configured to compare the actual flight path with a specified flight path of the unfinned envelope in a navigation comparison and determine a navigation instruction for the unfinned envelope based on the navigation comparison; a perturbation comparator configured to compare the navigation instruction with the monitored one or more perturbations in a perturbation comparison and determine a perturbation compensation based on the perturbation comparison; and

a propulsion coordinator in communication with the two or more propulsion elements, the propulsion coordinator configured to control propulsion values of each of the propulsion elements based on the navigation instruction and the perturbation compensation.
