Nav17Nav19

Nav17Nav19 is a fictional navigational framework used in science fiction literature and spaceflight simulation communities to describe a dual-layer approach to starship routing and hazard avoidance. The term combines two subsystems: Nav17, a deterministic route-planning module that translates star catalogs and celestial coordinates into optimized trajectories; and Nav19, a sensor-fusion and risk-assessment module that analyzes real-time environmental data, gravity fields, and anomaly maps to adjust course, speed, and burn profiles.

Originating in speculative tech manuals and fan-created universes, Nav17Nav19 is presented as an open architecture rather than a single product, allowing different writers and simulators to plug in their own sensor suites and data formats. The architecture typically includes data interfaces that ingest stellar catalogs, gravity wells, and plasma signatures; a route planner that computes energy-efficient paths under constraints; a hazard scanner that detects close approaches, radiation belts, and gravitational instabilities; and a decision engine that issues maneuver commands within safety margins.

In practice, Nav17Nav19 is valued for its modularity and its emphasis on hazard-aware routing, enabling ships to traverse complex regions such as multi-star systems or near astrophysical objects. Limitations in-universe include reliance on data fidelity and the potential for spoofed or outdated data to produce suboptimal routes.
