- Surface: Training in plotting and following a likely course over land or sea in order to reach a chosen destination in the most efficient way possible.
- Tracking: Extensive training in how to read the marks left by the passage of others, in order to follow them, but also to determine information such as their numbers, if they are carrying a heavy load or travelling light, if they were in a hurry, and so on.
- Void: Capacity with the unusual knowledge of how to plot and follow a course between celestial bodies within a system.
- Warp (Restricted): The ability to plot a course through the uncertain eddies and currents of the immaterium. A skill based on feeling as much as knowledge, it is impossible to accurately navigate the Warp without the ability to perceive it, which is why this skill is held exclusively by the mutant Navigators of the Navis Nobilite. Using this skill requires the Inheritor (Navis Nobilite) Talent.
Navigation is the skill of reading maps and contextualising the information for everything from simple trips to complex logistics. Travel between locations is more complicated than simply looking at a map and drawing a straight line. Even for routine surface travel terrain, weather conditions, traffic patterns, roads (should they even exist), and local wildlife are all important criteria for considering the best route to reach a destination. Travel through space adds vastly more complexity to any calculations due to the movement of planets involved as well as any intervening bodies, while travel through the warp requires abilities far beyond normal Humans.
