SLIDE 6

sailors have sextants onboard for emergencies

SLIDE 7

but many sailors are rusty with celestial navigation

SLIDE 8

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

SLIDE 9

Live updating sextant calculator with continuous potentiometer input

SLIDE 10

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

SLIDE 11

GPS

same functions can lose signal can lose power can be jammed
