sextants measure star locations to get coordinates

sailors have sextants onboard for emergencies

but many sailors are rusty with celestial navigation

What method can we use to read sextant angles? Can calculations be performed automatically?

Live updating sextant calculator with continuous potentiometer input

Can a solar-charged battery meet the power requirements long term? 10mA-h, 10 hours to charge

GPS same functions can lose signal can lose power can be jammed

future steps: - survey different power sources - additional angle/mirror sensing
