BEARINGS












VOLUME 0: ELEVATIONAL
VOLUME I: ASTEROIDAL
VOLUME II: INTERPLANETARY
VOLUME III: INTERSTELLAR











SUMMARY:
Navigators can use time tested  methods to determine Lines of Position (LOPs) during interstellar voyages. Examples include:
1)  Simplest LOP is course line from from Sol to destination star.
2)  Sextant sighting angles to nearby stars can generate additional LOPs.
When multiple LOPs cross course line at same position at same time, navigator has a successful "fix" to greatly increases his confidence in ship's position.  During cruise (constant velocity portion of  voyage), multiple fixes help the navigator accurately predict future positions.
CONCLUSION:  Bearings enable interstellar vessels to precisely track remaining distance. 
This will prove essential for decelerating at exact, required distance to destination.
