Methods and systems of prescribing navigational instructions to autonomous vehicle, aerial as well as terrestrial, are discussed. In one embodiment, mission relevant data is collected and passed to an assessment unit. The assessment unit assess data relevant to the mission, rules and authorizations. The assessment unit either approves the mission by sending mission instructions or denies the mission by sending a rejection response. A mission is an assembly of one or more navigational containers, a navigational container being a repository for navigational guidance and rule-based authorization assessment.
