    CelNav without sextants

    Yes,there are plenty of ways to navigate(blue water,ice/polar,land)using
    events and bodies without ever having a sextant.
    The Arabs (and other cultures from antiquety) used "latitude hooks" to find
    latitude from the altitude of Polaris.They also used devices even earlier in
    time (history) in conjuction with precomputed seasonal positions of Vega and
    other bodies.
    The polynesians used star positions,sea currents and other phenomina to
    navigate successfully in blue water voyages.
    The Inuits and other native polar people used seasonal celestial bodies and
    events to guide them across ice masses and water.
    Native American tribes used natural terrestrial points and seasonal
    celestial events and bodies to find their way across vast tracks of the
    plains and mountains.All the native peoples of the world used celestial
    events to remind them to move to new areas to hunt and plant.
    I got a Bris "sextant" not to long ago.Simple to use and based on kind of a
    sun "hook" technique.Some reduction is required from the raw altitudes it
    measures but the resulting line or lines it gives are fairly fast to obtain
    and fairly accurate.Ballpark accuracy.I've only played around with it in the
    backyard at a stationary position.
    Define what you mean by "accuracy".
