Navigate in open waters without a GPS. The phones camera is used to make sightings of the sun, moon, Venus, or Mars. The sighting results are plotted as lines of position with multiple sightings combined into a running fix. Your estimated position is displayed on a lat/lon grid. You can also use your sextant and take advantage of the built-in almanac and plotting tools.
