CamSextant vs Sailing Copilot

CamSextant is the easiest celestial navigation tool. It allows taking altitudes of celestial objects, using your phone as a sextant. It is a complete celestial navigation solution, with instrument, nautical almanac and celestial calculator. Point a celestial object and tap the image to capture the altitude and time. Stars and planets shown on screen in real time. Show constellation names and lines. Identify planets and navigation stars (from Hipparchus 150 catalog). The program can also speak the star names and altitudes (audio). Astronomic Position (AP) is automatically calculated once you have two sights. Calculate your astronomical position with less than 10 clicks. Perpetual nautical almanac using Astronomical Algorithms ( book by J. Meeus). If you take altitude observations of the same object, the average time/altitude are shown. You can calibrate the sextant horizon by reading the sea horizon altitude. Note that the phone is more like a bubble sextant: you don't need the sea horizon to use CamSextant. Anyway, click [Calibrate] button to save the correction. Calibration angle is subtracted from raw sensor reading. If you have a marine sextant at hand, you can edit the altitudes captured by the phone and get serious celestial navigation work done.

Sailing Copilot turns sailing data into clear, practical guidance you can use on the water. Instead of simply displaying wind, heading and boat speed, Sailing Copilot interprets that information to help you understand your point of sail and provides clear course, mainsail and jib guidance. SAILING GUIDANCE AT A GLANCE See your point of sail and get simple guidance for your course, mainsail and jib in a glanceable interface designed for use aboard a sailboat. AUTOMATIC WIND Sailing Copilot can automatically retrieve regional wind data based on your location, letting you get started without dedicated marine hardware. Weather-based wind is clearly identified as forecast data rather than an onboard measurement. LIVE NAVIGATION Use your iPhone's GPS and compass for heading and speed information. A built-in map shows your position and recent track. MARINE INSTRUMENT INPUT Sailing Copilot supports NMEA 0183 data from compatible Wi-Fi gateways using TCP or UDP. When suitable instrument data is available, the app can use it as an input to its guidance system. MANUAL & SIMULATION MODES No instruments? Enter wind conditions manually or use Simulation Mode to explore different headings, wind conditions and points of sail. See how changes in course and wind affect the guidance provided by Sailing Copilot. KNOW YOUR DATA SOURCE Sailing Copilot identifies whether key information is coming from marine instruments, weather data, manual input, your iPhone or simulation. Stale and fallback conditions are highlighted so you know when the preferred source is unavailable. FROM DATA TO GUIDANCE Sailing Copilot is built around a simple idea: sailing data becomes much more useful when it helps answer one important question: “What should I do?” Sailing Copilot provides advisory sailing guidance only. It is not a substitute for seamanship, proper training, onboard navigation equipment, weather awareness or the judgment of the skipper.
