Navigation involves management of the vessel’s movement in space, including superluminal travel between stellar systems and maneuvering the vessel around other vessels and objects at subluminal speeds.
All navigation requires knowledge of the vessel’s current location, speed and heading as well as the location and bearing of any vessels or objects in surrounding space. Movement over any distance necessitates establishing a heading that will get the vessel to the intended destination.
There are three main navigation modes.
Faster-Than-Light (FTL) navigation involves relativistic superluminal travel, enabling transit between star systems within hours or days. The vessel’s FTL Drive utilises powerful fields which warp space-time, significantly reducing the effective distance the vessel needs to travel between two points.
Travelling in manipulated space-time takes the vessel out of phase with surrounding space. This means the vessel is undetectable but also means that sensor readings or communication outside the drive field are not possible.
The vessel’s main engines provide thrust using magnetoplasma impulse technology. This uses superheated plasma to create a base level of thrust, which is accelerated using magnetic fields arranged in a carefully configured impulse pattern. Referred to colloquially as impulse engines, they can accelerate the vessel to 0.2c – one-fifth of the speed of light.
The impulse engines are also capable of varying the direction of thrust so as to alter the vessel’s heading. This process of turning the vessel while underway is referred to as maneuvering. This makes the powerful thrust of the impulse engines available to alter the heading of the vessel’s considerable mass relatively quickly and efficiently but also requires the vessel to be under way.
Impulse navigation is where encounters with other vessels are most likely and most tactical operations will occur.
The Reaction Control System (RCS) uses a number of small chemical rocket engines located around the vessel to make small and precise position or heading changes. RCS is used for establishing orbit, rendezvousing with another vessel or for docking.
RCS can alter the vessel’s position from stationary, but is not powerful enough to maneuver the vessel at impulse speeds.
Stellar cartography involes the identification of star systems and the mapping of their location so that vessels can naviagte to them.
This includes the identification of Atsronomical Objects (AOs) such as planets within the star system so that vessels can safely navigate within the star system once they reach it.
