Gravitational Navigation

Gravitational Navigation is the explorer end-tier research that improves expedition routing, rewards, and hostile contact handling.

Overview

Exploration Effects

Per level:

  • positive exploration rewards gain +5%
  • hostile encounter fleet size is reduced by 5%
  • empty expedition ticks lose 1 percentage point

That lost empty chance is split equally between:

  • resource finds
  • ship finds

So level 4 shifts the non-combat table by:

  • Empty: 50% -> 46%
  • Resource finds: 24% -> 26%
  • Ship finds: 15% -> 17%

Fleet-lost ticks stay at their normal 1% branch.
